## Menu
A control that opens a Drop containing plain Buttons.
The labels and behavior of the contained Buttons are described
via the `items` property.
You can provide a single function child that will be called with
'disabled', 'hover', 'focus', and 'drop' keys.
This allows you to customize the rendering of the Menu button
in those cases.
