17Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
18
19`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
20is highlighted, and the selected item has bolded text.
21
22    <paper-menu>
23      <paper-item>Item 1</paper-item>
24      <paper-item>Item 2</paper-item>
25    </paper-menu>
26
27An initial selection can be specified with the `selected` attribute.
28
29    <paper-menu selected="0">
30      <paper-item>Item 1</paper-item>
31      <paper-item>Item 2</paper-item>
32    </paper-menu>
33
34Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
35and multiple items can be selected.
36
37    <paper-menu multi>
38      <paper-item>Item 1</paper-item>
39      <paper-item>Item 2</paper-item>
40    </paper-menu>

56### Accessibility
57
58`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
59`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
60down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
61of a menu item will also focus it.
