##<paper-menu>
Material design: Menus
<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>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 |

<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.
##<paper-submenu>
<paper-submenu> is a nested menu inside of a parent <paper-menu>. It
consists of a trigger that expands or collapses another <paper-menu>:
<paper-menu>
<paper-submenu>
<paper-item class="menu-trigger">Topics</paper-item>
<paper-menu class="menu-content">
<paper-item>Topic 1</paper-item>
<paper-item>Topic 2</paper-item>
<paper-item>Topic 3</paper-item>
</paper-menu>
</paper-submenu>
<paper-submenu>
<paper-item class="menu-trigger">Faves</paper-item>
<paper-menu class="menu-content">
<paper-item>Fave 1</paper-item>
<paper-item>Fave 2</paper-item>
</paper-menu>
</paper-submenu>
<paper-submenu disabled>
<paper-item class="menu-trigger">Unavailable</paper-item>
<paper-menu class="menu-content">
<paper-item>Disabled 1</paper-item>
<paper-item>Disabled 2</paper-item>
</paper-menu>
</paper-submenu>
</paper-menu>Just like in <paper-menu>, the focused item is highlighted, and the selected
item has bolded text. Please see the <paper-menu> docs for which attributes
(such as multi and selected), and styling options are available for the
menu-content menu.
