| 11 Use to create nested menus inside of `core-menu` elements. | |
| 12 | |
| 13 <core-menu selected="0"> | |
| 14 | |
| 15 <core-submenu icon="settings" label="Topics"> | |
| 16 <core-item label="Topic 1"></core-item> | |
| 17 <core-item label="Topic 2"></core-item> | |
| 18 </core-submenu> | |
| 19 | |
| 20 <core-submenu icon="settings" label="Favorites"> | |
| 21 <core-item label="Favorite 1"></core-item> | |
| 22 <core-item label="Favorite 2"></core-item> | |
| 23 <core-item label="Favorite 3"></core-item> | |
| 24 </core-submenu> | |
| 25 | |
| 26 </core-menu> | |
| 27 | |
| 28 There is a margin set on the submenu to indent the items. | |
| 29 You can override the margin by doing: | |
| 30 | |
| 31 core-submenu::shadow #submenu { | |
| 32 margin-left: 20px; | |
| 33 } | |
| 34 | |
| 35 To style the item for the submenu, do something like this: | |
| 36 | |
| 37 core-submenu::shadow > #submenuItem { | |
| 38 color: blue; | |
| 39 } | |
| 40 | |
| 41 To style all the `core-item`s in the light DOM: | |
| 42 | |
| 43 polyfill-next-selector { content: 'core-submenu > #submenu > core-item'; } | |
| 44 core-submenu > core-item { | |
| 45 color: red; | |
| 46 } | |
| 47 | |
| 48 The above will style `Topic1` and `Topic2` to have font color red. | |
| 49 | |
| 50 <core-submenu icon="settings" label="Topics"> | |
| 51 <core-item label="Topic1"></core-item> | |
| 52 <core-item label="Topic2"></core-item> | |
| 53 </core-submenu> | |
