## Installation

### Option 1 - import from CDN:

Place these lines before any other code which is (or will be) using *Tagify* ([Example here](https://jsbin.com/jekuqap/edit?html))
```html
<script src="https://cdn.jsdelivr.net/npm/@yaireo/tagify"></script>
<script src="https://cdn.jsdelivr.net/npm/@yaireo/tagify/dist/tagify.polyfills.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/@yaireo/tagify/dist/tagify.css" rel="stylesheet" type="text/css" />
```

`Tagify` will then be available globally.
To load specific version use `@` - for example: `unpkg.com/@yaireo/tagify@3.1.0`

### option 2 - import as a *Node module*:
```sh
npm i @yaireo/tagify --save
```

## Basic Usage Examples

- Many demos with code examples can be [seen here](https://yaireo.github.io/tagify/)
- [CodeSandbox live demo](https://codesandbox.io/s/simple-tagify-setup-6pfi2)



```js
import Tagify from '@yaireo/tagify'

var inputElem = document.querySelector('input') // the 'input' element which will be transformed into a Tagify component
var tagify = new Tagify(inputElem, {
  // A list of possible tags. This setting is optional if you want to allow
  // any possible tag to be added without suggesting any to the user.
  whitelist: ['foo', 'bar', 'and baz', 0, 1, 2]
})
```

The above example shows the most basic `whitelist` array setting possible, with a mix
of *Strings* and *Numbers* but the array also support Objects whic a must-have property of `value`:

```js
whitelist: [{value: 'foo', id: '123', email: 'foo@whatever.com'}, ...]
```

The `value` property is what will be used when actually defining the `value` property of the original input element (`inputElem` in the example above) which was transformed
into a *Tagify* component, and so when the form data is sent to the server, it will contain all the values (which are the selected tags in the component).

For selected tags to show a different text than what is defined in `value` for a whitelist item, see the `tagTextProp` [setting](#settings)

⚠️ Important:
Don't forget to **include `tagify.css`** file in your project.
CSS location: `@yaireo/tagify/dist/tagify.css`
SCSS location: `@yaireo/tagify/src/tagify.scss`
[See SCSS usecase & example](https://github.com/yairEO/tagify/pull/282)

### Debugging
There are several places in the source code which emits `console.warn` logs to help identify issues.
<del>Those will only work if `Tagify.logger.enabled` flag is set to `true`</del>.
To disable the default logging, set the following global variable:


```js
window.TAGIFY_DEBUG = false

var tagify = new Tagify(...)
```

* Many useful custom [events](#events)
* Original input/textarea element values kept in sync with Tagify

## Building the project
Simply run `gulp` in your terminal, from the project's path ([Gulp](https://gulpjs.com) should be installed first).

Source files are this path: `/src/`

Output files, which are automatically generated using Gulp, are in: `/dist/`

### Output files:

Filename                             | Info
------------------------------------ | -----------------------------------------------------------
`tagify.esm.js`                      | ESM version. [see jsbin demo](https://jsbin.com/sulijap/edit?html,output)
`tagify.js`                          | *minified* UMD version, including its souremaps. This is the **main** file the package exports.
`tagify.polyfills.min.js`            | Used for old Internet Explorer browser support
`react.tagify.js`                    | Wrapper-only for React. [Read more](#react)
<del>`jQuery.tagify.min.js`</del>    | jQuery wrapper - same as `tagify.js`. Might be removed in the future. **(Deprecaded as of APR 24')**
`tagify.css`                         |


## Adding tags dynamically
```javascript
var tagify = new Tagify(...);

tagify.addTags(["banana", "orange", "apple"])

// or add tags with pre-defined properties

tagify.addTags([{value:"banana", color:"yellow"}, {value:"apple", color:"red"}, {value:"watermelon", color:"green"}])
```

## Output value
There are two possible ways to get the value of the tags:

1. Access the tagify's instance's `value` prop: `tagify.value` (Array of tags)
2. Access the *original* input's value: `inputElm.value` (Stringified Array of tags)

The most common way is to simply listen to the `change` event on the *original input*

```javascript
var inputElm = document.querySelector,
    tagify = new Tagify (inputElm);

inputElm.addEventListener('change', onChange)

function onChange(e){
  // outputs a String
  console.log(e.target.value)
}

```

### [Modify original input value format](https://jsbin.com/paxijaj/edit?html,js,output)

Default format is a JSON string:<br>
`'[{"value":"cat"}, {"value":"dog"}]'`

I **recommend** keeping this because some situations might have values such as addresses (tags contain commas):<br>
`'[{"value":"Apt. 2A, Jacksonville, FL 39404"}, {"value":"Forrest Ray, 191-103 Integer Rd., Corona New Mexico"}]'`

Another example for complex tags state might be disabled tags, or ones with custom identifier *class*:<br>
*(tags can be clicked, so delevopers can choose to use this to disable/enable tags)*<br>
`'[{"value":"cat", "disabled":true}, {"value":"dog"}, {"value":"bird", "class":"color-green"}]'`

To change the format, assuming your tags have no commas and are fairly simple:

```js
var tagify = new Tagify(inputElm, {
  originalInputValueFormat: valuesArr => valuesArr.map(item => item.value).join(',')
})
```

**Output:**<br>
`"cat,dog"`


## Ajax whitelist
Dynamically-loaded suggestions list (*whitelist*) from the server (as the user types) is a frequent need to many.

Tagify comes with its own loading animation, which is a very lightweight CSS-only code, and the <em>loading</em>
state is controlled by the method `tagify.loading` which accepts `true` or `false` as arguments.

Below is a basic example using the `fetch` API. I advise aborting the last request on any input before starting a new request.

<details>
  <summary>Example:</summary>

```javascript
var input = document.querySelector('input'),
    tagify = new Tagify(input, {whitelist:[]}),
    controller; // for aborting the call

// listen to any keystrokes which modify tagify's input
tagify.on('input', onInput)

function onInput( e ){
  var value = e.detail.value
  tagify.whitelist = null // reset the whitelist

  // https://developer.mozilla.org/en-US/docs/Web/API/AbortController/abort
  controller && controller.abort()
  controller = new AbortController()

  // show loading animation.
  tagify.loading(true)

  fetch('http://get_suggestions.com?value=' + value, {signal:controller.signal})
    .then(RES => RES.json())
    .then(function(newWhitelist){
      tagify.whitelist = newWhitelist // update whitelist Array in-place
      tagify.loading(false).dropdown.show(value) // render the suggestions dropdown
    })
}
```
</details>

## Persisted data

Sometimes the whitelist might be loaded asynchronously, and so any pre-filled value in the original input field
will be removed if the `enforceWhitelist` is set to `true`.

Tagify can automatically restore the last used `whitelist` by setting a ***unique id*** to the Tagify instance,
by using the *localstorage* to persist the `whitelist` & `value` data:

```js
var input = document.querySelector('input'),
    tagify = new Tagify(input, {
      id: 'test1',  // must be unique (per-tagify instance)
      enforceWhitelist: true,
    }),
```

## Edit tags
Tags that aren't `read-only` can be edited by double-clicking them (by default)
or by changing the `editTags` *setting* to `1`, making tags editable by single-clicking them.

The value is saved on `blur` or by pressing `enter` key. Pressing `Escape` will revert the change trigger `blur`.
<kbd>ctrl</kbd><kbd>z</kbd> will revert the change if an edited tag was marked as not valid (perhaps duplicate or blacklisted)

To prevent *all* tags from being allowed to be editable, set the `editTags` setting to `false` (or `null`).<br>
To do the same but for specific tag(s), set those tags' data with `editable` property set to `false`:

```html
<input value='[{"value":"foo", "editable":false}, {"value":"bar"}]'>
```


## Validations
For "regular" tags (not *mix-mode* or *select-mode*) the easiest way is to use the `pattern` setting and use a Regex, or
apply the `pattern` attribute directly on the `input` which will be "transformed" into a *Tagify* component (for vanilla code where the `input` tag is fully accessible to developers).

If the `pattern` setting does not meet your needs, use the [`validate` setting](#settings), which recieves a *tag data object* as an argument and should return `true` if validaiton is passing, or `false`/`string` of not.
A *string* may be returned as the reason of the validation failure so it would be printed as the `title` attribute of the invalid tag.

[Here's an example](https://jsbin.com/rojixul/edit?js,output) for async validation for an added tag. The idea is to listen to `"add"` event,
and when it fires, first set the tag to "loading" state, run an async call, and then set the *loading* state (of the tag) back to `false`.
If the custom async validation failed, call the `replaceTag` Tagify method and set the `__isValid` tag data property to the error string which will
be shown when hovering the tag.


Note - there is a setting to keep invalid tags ([`keepInvalidTags`](#settings))  and if it's set to `true`, the user can see the reason for the invalidation by
hovering the tag and see the browser's native tooltip via the `title` attribute:

```js
{
  empty      : "empty",
  exceed     : "number of tags exceeded",
  pattern    : "pattern mismatch",
  duplicate  : "already exists",
  notAllowed : "not allowed"
}
```

The texts for those (invalid tags) *titles* can be customized from the settings:

```js
new Tagify(inputElement, {
  texts: {
    duplicate: "Duplicates are not allowed"
  }
})
```

Or by directly manipulating the *Tagify* function *prototype*:

```js
Tagify.prototype.TEXTS = {...Tagify.prototype.TEXTS, {duplicate: "Duplicates are not allowed"}}
```

## Drag & Sort

To be able to sort tags by dragging, a 3rd-party script is needed.

I have made a very simple *drag & drop* (~`11kb` *unminified*) script which uses [HTML5 native API](https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API) and
it is available to download via [NPM](https://www.npmjs.com/package/@yaireo/dragsort) or [Github](https://github.com/yairEO/dragsort)
but any other *drag & drop* script may work. I could not find on the whole internet a decent lightweight script.

### [Integration example](https://codepen.io/vsync/pen/jOqYOVJ):

```js
var tagify = new Tagify(inputElement)

// bind "DragSort" to Tagify's main element and tell
// it that all the items with the below "selector" are "draggable"
var dragsort = new DragSort(tagify.DOM.scope, {
    selector: '.'+tagify.settings.classNames.tag,
    callbacks: {
        dragEnd: onDragEnd
    }
})

// must update Tagify's value according to the re-ordered nodes in the DOM
function onDragEnd(elm){
    tagify.updateValueByDOMTags()
}
```


## DOM Templates
It's possible to control the templates for some of the HTML elements Tagify is using by
modifying the `settings.templates` Object with your own custom functions which **must return** an *HTML string*.

Available templates are: `wrapper`, `input`, `tag`, `dropdown`, `dropdownItem`, `dropdownContent`, `dropdownHeader`, `dropdownFooter` and the optional `dropdownItemNoMatch`
which is a special template for rendering a suggestion item (in the dropdown list) only if there were no matches found for the typed input, for example:

```js
// ...more tagify settings...
templates: {
  dropdownItemNoMatch: data =>
    `<div class='${tagify.settings.classNames.dropdownItem}' value="noMatch" tabindex="0" role="option">
        No suggestion found for: <strong>${data.value}</strong>
    </div>`
}
```

[View templates](https://github.com/yairEO/tagify/blob/master/src/parts/templates.js)

### Example of overriding the `tag` template:

Each template function is automatically binded with `this` pointing to the current *Tagify* instance.
It is imperative to preserve the class names and also the `this.getAttributes(tagData)` for proper functionality.

```js
new Tagify(inputElem, {
  templates: {
    tag(tagData, tagify){
      return `<tag title="${(tagData.title || tagData.value)}"
              contenteditable='false'
              spellcheck='false'
              tabIndex="${this.settings.a11y.focusableTags ? 0 : -1}"
              class="${this.settings.classNames.tag} ${tagData.class ? tagData.class : ""}"
              ${this.getAttributes(tagData)}>
      <x title='' class="${this.settings.classNames.tagX}" role='button' aria-label='remove tag'></x>
      <div>
          <span class="${this.settings.classNames.tagText}">${tagData[this.settings.tagTextProp] || tagData.value}</span>
      </div>
    </tag>`,

    dropdownFooter(suggestions){
      var hasMore = suggestions.length - this.settings.dropdown.maxItems;

      return hasMore > 0
        ? `<footer data-selector='tagify-suggestions-footer' class="${this.settings.classNames.dropdownFooter}">
            ${hasMore} more items. Refine your search.
          </footer>`
        : '';
    }
  }
})
```

## Suggestions list

<p align="center">
  <img src="/docs/suggestions-list.apng" alt='suggestions list dropdown'/>
</p>

The suggestions list is a *whitelist Array* of *Strings* or *Objects* which was set in the [settings](#settings) Object when the Tagify instance was created, and can be set later directly on the instance: `tagifyInstance.whitelist = ["tag1", "tag2", ...]`.

The suggestions dropdown will be appended to the document's `<body>` element and will be rendered by default in a position below (bottom of) the Tagify element.
Using the keyboard arrows up/down will highlight an option from the list, and hitting the Enter key to select.

It is possible to tweak the list dropdown via 2 settings:

 - `enabled` - this is a numeral value that tells Tagify when to show the suggestions dropdown, when a minimum of N characters were typed.
 - `maxItems` - Limits the number of items the suggestions list will render

```javascript
var input = document.querySelector('input'),
    tagify = new Tagify(input, {
        whitelist : ['aaa', 'aaab', 'aaabb', 'aaabc', 'aaabd', 'aaabe', 'aaac', 'aaacc'],
        dropdown : {
            classname     : "color-blue",
            enabled       : 0,              // show the dropdown immediately on focus
            maxItems      : 5,
            position      : "text",         // place the dropdown near the typed text
            closeOnSelect : false,          // keep the dropdown open after selecting a suggestion
            highlightFirst: true
        }
    });
```

<p align="center"><b>Will render</b></p>

```html
<div class="tagify__dropdown tagify__dropdown--text" style="left:993.5px; top:106.375px; width:616px;">
    <div class="tagify__dropdown__wrapper">
      <div class="tagify__dropdown__item tagify__dropdown__item--active" value="aaab">aaab</div>
      <div class="tagify__dropdown__item" value="aaabb">aaabb</div>
      <div class="tagify__dropdown__item" value="aaabc">aaabc</div>
      <div class="tagify__dropdown__item" value="aaabd">aaabd</div>
      <div class="tagify__dropdown__item" value="aaabe">aaabe</div>
    </div>
</div>
```

By default searching the suggestions is using [fuzzy-search](https://en.wikipedia.org/wiki/Approximate_string_matching) (see [settings](#settings)).

If you wish to assign *alias* to items (in your suggestion list), add the `searchBy` property to *whitelist* items you wish
to have an *alias* for.

In the below example, typing a part of a string which is included in the `searchBy` property, for example *`land midd"`* -
the suggested item which matches the value "Israel" will be rendered in the suggestions (dropdown) list.

### [Example](https://yaireo.github.io/tagify/#section-extra-properties) for a suggestion item alias

```javascript
whitelist = [
    ...
    { value:'Israel', code:'IL', searchBy:'holy land, desert, middle east' },
    ...
]
```

Another handy setting is `dropdown.searchKeys` which, like the above `dropdown.searchBy` setting, allows
expanding the search of any typed terms to more than the `value` property of the whitelist items (if items are a *Collection*).

### Example whitelist:

```javascript
[
  {
    value    : 123456,
    nickname : "foo",
    email    : "foo@mail.com"
  },
  {
    value    : 987654,
    nickname : "bar",
    email    : "bar@mail.com"
  },
  ...more..
]
```

Modified `searchKeys` setting to also search in other keys:
```javascript
{
  dropdown: {
    searchKeys: ["nickname", "email"] //  fuzzy-search matching for those whitelist items' properties
  }
}
```

## Mixed-Content

[See demo here](https://yaireo.github.io/tagify/#section-mix)

This feature must be toggled using these [settings](#settings):

```js
{
  //  mixTagsInterpolator: ["{{", "}}"],  // optional: interpolation before & after string
  mode: 'mix',    // <--  Enable mixed-content
  pattern: /@|#/  // <--  Text starting with @ or # (if single, String can be used here instead of Regex)
}
```

When mixing text with tags, the original textarea (or input) element will have a value as follows:

    [[cartman]]⁠ and [[kyle]]⁠ do not know [[Homer simpson]]⁠

If the initial value of the textarea or input is formatted as the above example, Tagify will try to
automatically convert everything between `[[` & `]]` to a tag, if tag exists in the *whitelist*, so make
sure when the Tagify instance is initialized, that it has tags with the correct `value` property that match
the same values that appear between `[[` & `]]`.

Applying the setting `dropdown.position:"text"` is encouraged for mixed-content tags, because the suggestions list
weird when there is already a lot of content on multiple lines.

If a tag does not exist in the *whitelist*, it may be created by the user and all you should do is listen to the `add` event and update your local/remote state.

## Single-Value

Similar to native `<Select>` element, but allows typing text as value.

## React

See [**live demo**](https://codesandbox.io/s/tagify-react-wrapper-oempc) for React integration examples.
⚠️ Tagify is **not** a [controlled component](https://github.com/yairEO/tagify/issues/489#issuecomment-629316093).

A none-minified and raw source-code Tagify React component is exported from [`react.tagify.jsx`](https://github.com/yairEO/tagify/blob/master/src/react.tagify.jsx) and you can import it as seen in the below code example.
This React port will only work if your bundler can handle raw source-code in ES2015+ which is better for tree-shaking.

---
### Update regarding `onChange` prop:

I have changed how the `onChange` works internally within the Wrapper of Tagify
so as of *March 30, 2021* the `e` argument will include a `detail` parameter with the value as string.
There is no more `e.target`, and to access the original DOM input element, do this: `e.detail.tagify.DOM.originalInput`.

----

> Note: You will need to import Tagify's CSS also, either by JavaScript or by SCSS `@import` (which is preferable)
> Also note that you will need to use [*dart-sass*](https://www.npmjs.com/package/sass) and not *node-sass* in order to compile the file.

```javascript
import { useCallback, useRef } from 'react'
import Tags from '@yaireo/tagify/react' // React-wrapper file
import '@yaireo/tagify/dist/tagify.css' // Tagify CSS

const App = () => {
    // on tag add/edit/remove
    const onChange = useCallback((e) => {
        console.log("CHANGED:"
            , e.detail.tagify.value // Array where each tag includes tagify's (needed) extra properties
            , e.detail.tagify.getCleanValue() // Same as above, without the extra properties
            , e.detail.value // a string representing the tags
        )
    }, [])

    return (
        <Tags
            whitelist={['item 1', 'another item', 'item 3']}
            placeholder='Add some tags'
            settings={{
                blacklist: ["xxx"],
                maxTags: 4,
                dropdown: {
                    enabled: 0 // always show suggestions dropdown
                }
            }}
            defaultValue="a,b,c" // initial value
            onChange={onChange}
        />
    )
}
```

To gain full access to Tagify's (instance) inner methods, A custom `ref` can be used:

```jsx
import Tags, {MixedTags} from "@yaireo/tagify/react";

...
const tagifyRef = useRef()
...
<Tags tagifyRef={tagifyRef} ... />

// or mix-mode
<MixedTags
  settings={...}
  onChange={...}
  defaultValue={`This is a textarea which mixes text with [[{"value":"tags"}]].`}
/>
```

`<MixedTags>` component is a shorthand for `<Tags InputMode="textarea">`

#### Updating the component's state

The `settings` prop is **only used once** in the initialization process, please do not update it afterwards.

## Vue

I don't know *Vue* at all and this thin wrapper was built by a friend who knows.
To import the [wrapper file](https://github.com/yairEO/tagify/blob/master/dist/tagify.vue), use the import path `@yaireo/tagify/vue`


## jQuery version

This variant of Tagify code has been **deprecated** because it doesn't really add much in terms of ease-of-use.
I only made it so it would be possible to use jQuery selectors & chaining but the (jQuery) port really isn't needed
when implementing Tagify within a jQuery code.

Below is the documentation for previous Tagify packages versions which included support:

#### `jQuery.tagify.js`

A jQuery wrapper version is also available, but I advise not using it because it's basically the exact same as the "normal"
script (non-jqueryfied) and all the jQuery's wrapper does is allowing to chain the event listeners for ('add', 'remove', 'invalid')

```javascript
$('[name=tags]')
    .tagify()
    .on('add', function(e, tagData){
        console.log('added', ...tagData)  // data, index, and DOM node
    });
```

Accessing methods can be done via the [`.data('tagify')`](https://api.jquery.com/data):

```javascript
$('[name=tags]').tagify();
// get tags from the server (ajax) and add them:
$('[name=tags]').data('tagify').addTags('aaa, bbb, ccc')
````

## HTML input & textarea attributes

The below list of *attributes* affect *Tagify*.<br>
These can also be set by Tagify [settings](#settings) Object manually, and not *declerativly* (via attributes).

Attribute         | Example                                               | Info
----------------- | ----------------------------------------------------- | --------------------
[pattern](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/pattern) | <pre lang=html>`<input pattern='^[A-Za-z_✲ ]{1,15}$'>`</pre>               | Tag Regex pattern which tag input is validated by.
[placeholder](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefplaceholder) | <pre lang=html>`<input placeholder='please type your tags'>`</pre>        | This attribute's value will be used as a constant placeholder, which is visible unless something is being typed.
readOnly          | <pre lang=html>`<input readOnly>`</pre> | No user-interaction (add/remove/edit) allowed.
autofocus         | <pre lang=html>`<input autofocus>`</pre> | Automatically focus the the Tagify component when the component is loaded
required          | <pre lang=html>`<input required>`</pre> | Adds a `required` attribute to the Tagify wrapper element. Does nothing more.



## Caveats
- `<input>` wrapped in a `<label>` doesn't work - [#1219](https://github.com/yairEO/tagify/issues/1219) and so Tagify internally sets the label's `for` attribute to an empty string, so clicking the Tagify component will not blur it and re-focus on the hidden input/textarea element Tagify is "connected" to

## FAQ
List of questions & scenarios which might come up during development with Tagify:

<details>
  <summary><strong>Dynamic whitelist</strong></summary>
The whitelist initial value is set like so:

```js
const tagify = new Tagify(tagNode, {
  whitelist: ["a", "b", "c"]
})
```

If changes to the whitelist are needed, they should be done like so:

**Incorrect:**

```js
tagify.settings.whitelist = ["foo", "bar"]
```

**Correct:**
```js
// set the whitelist directly on the instance and not on the "settings" property
tagify.whitelist = ["foo", "bar"]
```
</details>

---

<details>
  <summary><strong>tags/whitelist data structure</strong></summary>

Tagify does not accept just *any* kind of data structure.<br>
If a tag data is represented as an `Object`, it **must** contain a **unique** property `value`
which Tagify uses to check if a tag already exists, among other things, so make sure it is present.

**Incorrect:**

```javascript
[{ "id":1, "name":"foo bar" }]
```

**Correct:**

```javascript
[{ "id":1, "value": 1, "name":"foo bar" }]
```

```javascript
[{ "value":1, "name":"foo bar" }]
```

```javascript
[{ "value":"foo bar" }]
```

```javascript
// ad a simple array of Strings
["foo bar"]
```
</details>

---

<details>
  <summary><strong>Save changes (Ex. to a server)</strong></summary>

In framework-less projects, the developer should save the state of the Tagify component (somewhere), and
the question is:<br/>
**when should the state be saved?**
On every change made to *Tagify's* internal state (`tagify.value` via the `update()` method).<br>


```javascript
var tagify = new Tagify(...)

// listen to "change" events on the "original" input/textarea element
tagify.DOM.originalInput.addEventListener('change', onTagsChange)

// This example uses async/await but you can use Promises, of course, if you prefer.
async function onTagsChange(e){
  const {name, value} = e.target
  // "imaginary" async function "saveToServer" should get the field's name & value
  await saveToServer(name, value)
}
```

If you are using *React/Vue/Angular* or any "modern" framework, then you already know how to
attach "onChange" event listeners to your `<input>`/`<textarea>` elements, so the above is irrelevant.
</details>

----

<details>
  <summary><strong>Render tags in one single line</strong></summary>

Stopping tags from wrapping to new lines, add this to your `.tagify` *selector CSS Rule*:

```css
flex-wrap: nowrap;
````
</details>

----

<details>
  <summary><strong>Submit on `Enter` key</strong></summary>

Tagify internally has `state` property, per `Tagify` instance
and this may be useful for a variety of things when implementing a specific scenario.

```js
var tagify = new Tagify(...)
var formElm = document.forms[0]; // just an example

tagify.on('keydown', onTagifyKeyDown)

function onTagifyKeyDown(e){
  if( e.detail.event.key == 'Enter' &&  // "enter" key pressed
      !tagify.state.inputText &&        // assuming user is not in the middle or adding a tag
      !tagify.state.editing             // user not editing a tag
    ){
    setTimeout(() => formElm.submit())  // put some buffer to make sure tagify has done with whatever, to be on the safe-side
  }

}
```
</details>

## CSS Variables

> Learn more about [CSS Variables](https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties)) (custom properties)

Tagify's utilizes *CSS variables* which allow easy customization without the need to manually write CSS.
If you do wish to heavily style your Tagify components, then you can (and should) use the below variables within
your modified styles as much as you can.

For a *live* example, see the [demos page](https://yaireo.github.io/tagify/#section-different-look).

## Methods

`Tagify` is [prototype](https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Objects/Object_prototypes) based and There are many methods, but I've chosen to list the most relevant ones:

Name                       | Parameters                                                                              | Info

`destroy`                  |                                                                                         | Reverts the input element back as it was before Tagify was applied
`removeAllTags`            |                                                                                         | Removes all tags and resets the original input tag's value property
`addTags`                  | <ol><li>`Array`/`String`/`Object` tag(s) to add</li><li>`Boolean` clear input after adding</li><li>`Boolean` - skip adding invalids</li><ol>  | Accepts a String (word, single or multiple with a delimiter), an Array of Objects (see above) or Strings.
`addMixTags`               | `Array`/`String`                                                                        | Bypasses the normalization process in `addTags`, forcefully adding tags at the last caret location or at the end, if there's no last caret location saved (at `tagify.state.selection`)
`removeTags`               | <ol><li>`Array`/`HTMLElement`/`String` tag(s) to remove</li><li>`silent` does not update the component's value</li><li>`tranDuration` Transition duration (in `ms`)</li></ul> | (#502) Remove single/multiple Tags. When nothing passed, removes last tag. <ul><li>`silent` - A flag, which when turned on, does not remove any value and does not update the original input value but simply removes the tag from tagify</li><li>`tranDuration` - delay for animation, after which the tag will be removed from the DOM</li></ul>
`addEmptyTag`              | `Object` <sub>(`tagData`)</sub>                                                         | Create an empty tag (optionally with pre-defined data) and enters "edit" mode directly. [See demo](https://yaireo.github.io/tagify#section-different-look)

## Events

To listen to `tagify` events use the `.on(EVENT_NAME, EVENT_CALLBACK_REFERENCE)` method and stop listening use the `.off(EVENT_NAME, EVENT_CALLBACK_REFERENCE)`

All triggered events return the instance's scope (tagify).<br>
See `e.detail` for custom-event additional data.

<details>
  <summary>Example 1</summary>

```javascript
var tagify = new Tagify(...)

// events can be chainable, and multiple events may be binded for the same callback
tagify
  .on('input', onInput)
  .on('edit:input edit:updated edit:start edit:keydown', e => console.log(e.type, e.detail))

function onInput(e) {
  console.log(e.detail)
}

// later in the code you might do to unsubscribe the event listener with a specific callback
tagify.off('input', onInput)
```
</details>

<details>
  <summary>Example 2</summary>

```javascript
var tagify = new Tagify(inputNode, {
  callbacks: {
    "change": (e) => console.log(e.detail),
    "dropdown:show": (e) => console.log(e.detail)
  }
})
```
</details>

Name               | Info
------------------ | --------------------------------------------------------------------------
change             | Any change to the value has occurred. `e.detail.value` callback listener argument is a *String*
add                | A tag has been added
remove             | A tag has been removed ([use `removeTag`](https://github.com/yairEO/tagify/issues/222) instead with *jQuery*)
invalid            | A tag has been added but did not pass validation. See [event detail](https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Creating_and_triggering_events)
input              | [Input](https://developer.mozilla.org/en-US/docs/Web/Events/input) event, when a tag is being typed/edited. `e.detail` exposes `value`, `inputElm` & `isValid`
paste              | Text pasted (not while editing a tag). The pasted text might or might not have been converted into tags, depneding if `pasteAsTags` setting is set to `false`
click              | Clicking a tag. Exposes the tag element, its index & data
dblclick           | Double-clicking a tag
keydown            | When Tagify input has focus and a key was pressed
focus              | The component currently has focus
blur               | The component lost focus
edit:input         | Typing inside an edited tag
edit:beforeUpdate  | Just before a tag has been updated, while still in "edit" mode
edit:updated       | A tag as been updated (changed view editing or by directly calling the `replaceTag()` method)
edit:start         | A tag is now in "edit mode"
edit:keydown       | keydown event while an edited tag is in focus
dropdown:show      | Suggestions dropdown is to be rendered. The dropdown DOM node is passed in the callback, [see demo](https://yaireo.github.io/tagify/#section-basic).
dropdown:hide      | Suggestions dropdown has been removed from the DOM
dropdown:select    | Suggestions dropdown item selected (by mouse/keyboard/touch)
dropdown:scroll    | Tells the percentage scrolled. (`event.detail.percentage`)
dropdown:noMatch   | No whitelist suggestion item matched for the typed input. At this point it is possible to manually set `tagify.suggestedListItems` to any possible custom value, for example: `[{ value:"default" }]`
dropdown:updated   | Fired when the dropdown list is re-filtered while suggestions list is visible and a tag was removed so it was re-added as a suggestion

## Hooks

**Promise**-based hooks for *async* program flow scenarios.

Allows to "hook" (intervene) at certain points of the program, which were selected as a suitable place to
**pause** the program flow and wait for further instructions on how/if to proceed.

<details>
  <summary>For example, if a developer wishes to add a (native) confirmation popup before a tag is removed (by a user action):
</summary>

```javascript
var input = document.querySelector('input')
var tagify = new Tagify(input,{
    hooks: {
        /**
         * Removes a tag
         * @param  {Array}  tags [Array of Objects [{node:..., data:...}, {...}, ...]]
         */
        beforeRemoveTag : function( tags ){
            return new Promise((resolve, reject) => {
                confirm("Remove " + tags[0].data.value + "?")
                    ? resolve()
                    : reject()
            })
        }
    }
})
```
</details>

Can also use the `disabled` attribute on the original input element. To update this after initialization use the setter `tagify.userInput`
focusable                      | <sub>Boolean</sub>           | true                                        | Allow the component as a whole to recieve focus. Implementations of Tagify without an external border should not allow 'focusability' which causes unwanted behaviour. ([use-case example](file:///C:/Users/vsync/projects/tagify/index.html#section-different-look))

autoComplete.tabKey            | <sub>Boolean</sub>           | false                                       | If `true`, pressing `tab` key would only auto-complete (if a suggesiton is highlighted) but will not convert to a tag (like `rightKey` does) also, unless clicked again (considering the `addTagOn` setting).
whitelist                      | <sub>Array</sub>             | `[]`                                        | An array of allowed tags (*Strings* or *Objects*). When using *Objects* in the *whitelist* array a `value` property is a must & should be unique. <br/>Also, the *whitelist used for auto-completion when `autoCompletion.enabled` is `true`
blacklist                      | <sub>Array</sub>             | `[]`                                        | An array of tags which aren't allowed

A *string* may be returned as the reason for the validation failure.
