-`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
-is highlighted, and the selected item has bolded text.

-      <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 item can be selected.
-
-    <paper-menu multi>
-      <paper-item>Item 1</paper-item>
-      <paper-item>Item 2</paper-item>
-    </paper-menu>

-`--paper-menu-color`               | Menu foreground color                                            | `--primary-text-color`

-### 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.
