##<iron-collapse>
`iron-collapse` creates a collapsible block of content. By default, the content
will be collapsed. Use `opened` or `toggle()` to show/hide the content.
```html
<button on-click="toggle">toggle collapse</button>
<iron-collapse id="collapse">
<div>Content goes here...</div>
</iron-collapse>
...
toggle: function() {
this.$.collapse.toggle();
}
```
`iron-collapse` adjusts the max-height/max-width of the collapsible element to show/hide
the content. So avoid putting padding/margin/border on the collapsible directly,
and instead put a div inside and style that.
```html
<style>
.collapse-content {
padding: 15px;
border: 1px solid #dedede;
}
</style>
<iron-collapse>
<div class="collapse-content">
<div>Content goes here...</div>
</div>
</iron-collapse>
```
### Styling
The following custom properties and mixins are available for styling:
| Custom property | Description | Default |
| --- | --- | --- |
| `--iron-collapse-transition-duration` | Animation transition duration | `300ms` |
|
