| 11 `paper-tabs` is a `core-selector` styled to look like tabs. Tabs make it easy to
| |
| 12 explore and switch between different views or functional aspects of an app, or | |
| 13 to browse categorized data sets. | |
| 14 | |
| 15 Use `selected` property to get or set the selected tab. | |
| 16 | |
| 17 Example: | |
| 18 | |
| 19 <paper-tabs selected="0"> | |
| 20 <paper-tab>TAB 1</paper-tab> | |
| 21 <paper-tab>TAB 2</paper-tab> | |
| 22 <paper-tab>TAB 3</paper-tab> | |
| 23 </paper-tabs> | |
| 24 | |
| 25 See <a href="#paper-tab">paper-tab</a> for more information about | |
| 26 `paper-tab`. | |
