  14 `<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
  15 is highlighted, and the selected item has bolded text.
  16
  17     <paper-menu>
  18       <paper-item>Item 1</paper-item>
  19       <paper-item>Item 2</paper-item>
  20     </paper-menu>
  21
  22 An initial selection can be specified with the `selected` attribute.
  23
  24     <paper-menu selected="0">
  25       <paper-item>Item 1</paper-item>
  26       <paper-item>Item 2</paper-item>
  27     </paper-menu>
  28
  29 Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
  30 and multiple item can be selected.
  31
  32     <paper-menu multi>
  33       <paper-item>Item 1</paper-item>
  34       <paper-item>Item 2</paper-item>

  51 ### Accessibility
  52
  53 `<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
  54 `aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
  55 down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
  56 of a menu item will also focus it.
