When the drop down menu on the master banner drops it is covered or partially covered by the layout area below and can't be read. If I put the navbar in the layout area it covers anything below and is readable. I don't want to make the master banner so big it will accommodate the biggest menu, nor do I want to have to put a navbar in the layout area on each page. What will make the menu behave in the banner area like it does in the layout area?
