# Tooltip for Angular

**Personal customization. Original package [here](https://www.npmjs.com/package/@webed/angular-tooltip).**

The tooltip is a pop-up tip that appears when you hover over an item or click on it.

## Installation

Install the npm package.

    npm i @nnevva/angular-tooltip2
        
Import `Ng2Module`:

```ts
import { TooltipDirective } from '@nnevva/angular-tooltip2';
 
@Component({
    imports: [ TooltipDirective ]
}) 
```

## Usage
    
Options can be set in the directive tag, so they have the highest priority.

```html
<span tooltip="Tooltip" placement="top" showDelay="500">Tooltip on top</span>
```

You may pass as an object:

```html
<span tooltip="Tooltip" [options]="myOptions">Tooltip on left</span>
```
```ts
myOptions = {
    'placement': 'left',
    'showDelay': 500
}
```

You can pass HTML as content :

```html
<span tooltip="<p>Hello i'm a <strong>bold</strong> text!</p>">
  Tooltip with HTML content
</span>
```

```html
<ng-template #HtmlContent>
  <p>Hello i'm a <strong>bold</strong> text!</p>
</ng-template>

<span [tooltip]="HtmlContent" contentType="template">
  Tooltip with template content
</span>
```

## Set default values

Create a file with your settings, for example:
```ts
import { TooltipOptions } from 'angular-tooltip';

export const MyDefaultTooltipOptions: TooltipOptions = {
  'show-delay': 500
}
```
    
And pass your parameters when importing the module:
```ts
import { TooltipModule, TooltipOptions } from 'angular-tooltip';
import { MyDefaultTooltipOptions } from './my-default-options';
 
@NgModule({
    providers: [ 
     { provide:TooltipOptions,useValue: MyDefaultTooltipOptions }
    ]
})
```
