JavaScript will handle the dropdown toggle and maybe some animations. The dropdown should toggle when the user clicks on the arrow, perhaps a checkbox hack or a simple show/hide with click event. Also, adding a click outside to close the dropdown if it's open. Maybe some class toggles for active states.
