+ |
+The `<core-selection>` element is used to manage selection state. It has no |
+visual appearance and is typically used in conjunction with another element. |
+For example, [core-selector](#core-selector) |
+use a `<core-selection>` to manage selection. |
+ |
+To mark an item as selected, call the `select(item)` method on |
+`<core-selection>`. The item itself is an argument to this method. |
+ |
+The `<core-selection>`element manages selection state for any given set of |
+items. When an item is selected, the `core-select` event is fired. |
+ |
+The attribute `multi` indicates if multiple items can be selected at once. |
+ |
+Example: |
+ |
+ <polymer-element name="selection-example"> |
+ <template> |
+ <style> |
+ polyfill-next-selector { content: ':host > .selected'; } |
+ ::content > .selected { |
+ font-weight: bold; |
+ font-style: italic; |
+ } |
+ </style> |
+ <ul on-tap="{{itemTapAction}}"> |
+ <content></content> |
+ </ul> |
+ <core-selection id="selection" multi |
+ on-core-select="{{selectAction}}"></core-selection> |
+ </template> |
+ <script> |
+ Polymer('selection-example', { |
+ itemTapAction: function(e, detail, sender) { |
+ this.$.selection.select(e.target); |
+ }, |
+ selectAction: function(e, detail, sender) { |
+ detail.item.classList.toggle('selected', detail.isSelected); |
+ } |
+ }); |
+ </script> |
+ </polymer-element> |
+ |
+ <selection-example> |
+ <li>Red</li> |
+ <li>Green</li> |
+ <li>Blue</li> |
