User interface helper for dropdown select

Permalink
Hi,
i want to build a theme where the menu will displayed as dropdown <select>/<option>. But im not satisfied with the user interface.
is there any way to call this dropdown menu so the interface will be shown like dropdown at the dashboard?

will ui helper do this?
$ih = Loader::helper(‘concrete/interface);


if can, how should i call this into my menu?

thanks anyway...
