title: Widget Plugin
---

The widget plugin provides the functionality for collapsing, expanding and removing a card. 

##### Usage
This plugin can be activated as a jQuery plugin or using the data api. 

###### Data API
{: .text-bold }

This plugin provides two data-api attributes. Any element using one of the following attributes should be placed within the `.card-tools` div, which is usually in the card header. For more information about the [card HTML structure]({% link components/cards.md %}), visit the card component documentation 

`data-widget="collapse"`
<br />
This attribute, when attached to a button, allows the box to be collapsed/expanded when clicked.

###### jQuery
{: .text-bold }
To activate any button using jQuery, you must provide the removeTrigger and collapseTrigger options. Otherwise, the plugin will assume the default `data-widget` selectors. 

```js
$('#my-card').Widget(options)
```

##### Options
{: .mt-4}

|---
| Name | Type | Default | Description
|-|-|-|-
|animationSpeed | Number | 300 | Speed of slide down/up animation in milliseconds.
|collapseTrigger | String | `[data-widget="remove"]` | jQuery selector to the element responsible for collapsing the box.
|removeTrigger | String | `[data-widget="collapse"]` | jQuery selector to the element responsible for removing the box.
{: .table .table-bordered .bg-light}

> ##### Tip!
> You can use any option via the data-attributes like this.
> ```html
> <button type="button" class="btn btn-tool" data-widget="collapse" data-animation-speed="1000"><i class="fas fa-minus"></i></button>
> ```
{: .quote-info}
