My website (www.txfannin.org) is very content heavy and thus requires multiple menu choices. As the view port size decreases I move main menu item to a master dropdown menu item which thus becomes the mobile toggle menu item. But, I noticed something interesting with the menu organization.
The mobile menu has multiple option some with further dropdown items. The oddity is that if the last item in the list is a dropdown item then only one of the dropdown items will show (should be 4).
