Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
is highlighted, and the selected item has bolded text.
<paper-menu>
<paper-item>Item 1</paper-item>
<paper-item>Item 2</paper-item>
</paper-menu>
An initial selection can be specified with the `selected` attribute.
<paper-menu selected="0">
<paper-item>Item 1</paper-item>
<paper-item>Item 2</paper-item>
</paper-menu>
Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
and multiple items can be selected.
<paper-menu multi>
<paper-item>Item 1</paper-item>
<paper-item>Item 2</paper-item>
</paper-menu>
### Styling
The following custom properties and mixins are available for styling:
Custom property | Description | Default
----------------|-------------|----------
`--paper-menu-background-color` | Menu background color | `--primary-background-color`
`--paper-menu-color` | Menu foreground color | `--primary-text-color`
`--paper-menu-disabled-color` | Foreground color for a disabled item | `--disabled-text-color`
`--paper-menu` | Mixin applied to the menu | `{}`
`--paper-menu-selected-item` | Mixin applied to the selected item | `{}`
`--paper-menu-focused-item` | Mixin applied to the focused item | `{}`
`--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}`
### Accessibility
`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
of a menu item will also focus it.
