Yes I mean the hover is not working. Only when you click on the parent menu, so the top menu, then you get a bar under the menu and the submenu opens. The colorbar under the menu shows you where you are in your menu. When the menu that has a submenu is selected than only with that menu the submenu will come up on hover. The other menu's with submenu's will not open the submenu on hover.
I hope I am clear with my explanation, always hard to make it visual for you. Wait I will make a print for you. See the menu with the blue bar under it... that is the menu that will open the submenu on hover.. The menu's next to it, won't open on hover.
Hope this helps
