- * @module Polymer Elements
- */
-/**
- * polymer-selector is used to manage a list of elements that can be selected.
- * The attribute "selected" indicates which item element is being selected.
- * The attribute "multi" indicates if multiple items can be selected at once.
- * Tapping on the item element would fire "polymer-activate" event. Use
- * "polymer-select" event to listen for selection changes.
- *
- * Example:
- *
- *     <polymer-selector selected="0">
- *       <div>Item 1</div>
- *       <div>Item 2</div>
- *       <div>Item 3</div>
- *     </polymer-selector>
- *
- * polymer-selector is not styled.  So one needs to use "polymer-selected" CSS
- * class to style the selected element.
- *
- *     <style>
- *       .item.polymer-selected {
- *         background: #eee;
- *       }
- *     </style>
- *     ...
- *     <polymer-selector>
- *       <div class="item">Item 1</div>
- *       <div class="item">Item 2</div>
- *       <div class="item">Item 3</div>
- *     </polymer-selector>
- *
- * @class polymer-selector
- */
-/**
- * Fired when an item's selection state is changed. This event is fired both
- * when an item is selected or deselected. The `isSelected` detail property
- * contains the selection state.
- *
- * @event polymer-select
- * @param {Object} detail
- *   @param {boolean} detail.isSelected true for selection and false for deselection
- *   @param {Object} detail.item the item element
- */
-/**
- * Fired when an item element is tapped.
- *
- * @event polymer-activate
- * @param {Object} detail
- *   @param {Object} detail.item the item element
