Action Menu

This component provides a dropdown menu of action items. When closed, it displays a text-only button, icon-only button, or a selector box. Selecting a menuitem completes the associated action and closes the menu. It should have at least one wm-menuitem component as a child.

After an action is executed make sure to properly handle focus for keyboard users.
