> A multi-select component with nested options support for Vue 3. Thank to [riophae](https://github.com/riophae/vue-treeselect) and his sources and library for vue 2 taken as basis.

Breaking changes from his library:

* property `value` => `modelValue`
* event `input` => `updated:modelValue`
* Now use slots with `<template>`

### Features

- Single & multiple select with nested options support
- Fuzzy matching
- Async searching
- Delayed loading (load data of deep level options only when needed)
- Keyboard support (navigate using <kbd>Arrow Up</kbd> & <kbd>Arrow Down</kbd> keys, select option using <kbd>Enter</kbd> key, etc.)
- Rich options & highly customizable
- Supports a wide range of browsers (see [below](#browser-compatibility))
- RTL support

*Requires Vue 3.0+*

### Getting Started

It's recommended to install vue3-treeselect via npm, and build your app using a bundler like [webpack](https://webpack.js.org/).

```bash
npm install --save vue3-treeselect
```

This example shows how to integrate vue3-treeselect with your [Vue SFCs](https://vuejs.org/v2/guide/single-file-components.html).

```vue
<!-- Vue SFC -->
<template>
  <div id="app">
    <treeselect v-model="value" :multiple="true" :options="options" />
  </div>
</template>

<script>
  // import the component
  import Treeselect from 'vue3-treeselect'
  // import the styles
  import 'vue3-treeselect/dist/vue3-treeselect.css'

  export default {
    // register the component
    components: { Treeselect },
    data() {
      return {
        // define the default value
        value: null,
        // define options
        options: [ {
          id: 'a',
          label: 'a',
          children: [ {
            id: 'aa',
            label: 'aa',
          }, {
            id: 'ab',
            label: 'ab',
          } ],
        }, {
          id: 'b',
          label: 'b',
        }, {
          id: 'c',
          label: 'c',
        } ],
      }
    },
  }
</script>
```

If you just don't want to use webpack or any other bundlers, you can simply include the standalone UMD build in your page. In this way, make sure Vue as a dependency is included before vue3-treeselect.

```html
<html>
  <head>
    <!-- include Vue 2.x -->
    <script src="https://cdn.jsdelivr.net/npm/vue@next"></script>
    <!-- include vue-treeselect & its styles. you can change the version tag to better suit your needs. -->
    <script src="https://cdn.jsdelivr.net/npm/vue3-treeselect@^0.1.0/dist/vue3-treeselect.umd.min.js"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/vue3-treeselect@^0.1.0/dist/vue3-treeselect.min.css">
  </head>
  <body>
    <div id="app">
      <treeselect v-model="value" :multiple="true" :options="options" />
    </div>
  </body>
  <script>
      createApp({
          data: {
            // define the default value
            value: null,
            // define options
            options: [ {
            id: 'a',
            label: 'a',
            children: [ {
                id: 'aa',
                label: 'aa',
            }, {
                id: 'ab',
                label: 'ab',
            } ],
            }, {
            id: 'b',
            label: 'b',
            }, {
            id: 'c',
            label: 'c',
            } ],
        },
      })
        .component('treeselect', VueTreeselect.Treeselect)
        .mount('#app')

  </script>
</html>
```

### Documentation for vue 2 & Live Demo. Be careful with breaking changes above.

[Visit the website](https://vue-treeselect.js.org/)

Note: please use a desktop browser since the website hasn't been optimized for mobile devices.

### Browser Compatibility

- Chrome
- Edge
- Firefox
- Safari

It should function well on IE9, but the style can be slightly broken due to the lack of support of some relatively new CSS features, such as `transition` and `animation`. Nevertheless it should look 90% same as on modern browsers.
