- * @fileoverview
- * `cr-collapse` creates a collapsible block of content. By default, the content
- * will be collapsed. Use `opened` or `toggle()` to show/hide the content.
- * `cr-collapse` adjusts the height/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.
- *
- * When a `cr-collapse` is toggled, its `opened` field changes immediately, but
- * its show/hide animation finishes some time afterward. To determine if the
- * element is actually shown in the UI, check for the `cr-collapse-closed` CSS
- * class.
- *
- * Example:
- *     <style>
- *       #collapse-content {
- *         padding: 15px;
- *       }
- *     </style>
- *     <button on-click="{{toggle}}">toggle collapse</button>
- *     <cr-collapse id="collapse">
- *       <div id="collapse-content">
- *         Content goes here...
- *       </div>
- *     </cr-collapse>
- *
- *     ...
- *
- *     toggle: function() {
- *       this.$.collapse.toggle();
- *     }
- *
- * @element cr-collapse
