I have a custom global navigation menu which I have placed above the ribbon. It looks great, except that when I have a tab open that shows the sharepoint ribbon, the drop-down menus appear transparent when they hang over the buttons on the ribbon. It is as if the ribbon buttons are flying out 3d. very strange.
My drop-down menus look fine on all pages where the ribbon isn't showing.
Any ideas on how to make the ribbon buttons stay at the back?
