I have a javascript that dynamically displays drop-down navigation menu 
items from a navigation bar across the top of each page.  Works great.

Here is the catch: if the number of menu items creates a long enough list, 
the list can reach down the page far enough to reach drop down list boxes, 
list boxes, text boxes, etc.  The problem is that the ddlists et al will 
stay "in front" of the menu that drops down.  Some do, some don't, but 
each seems to behave consistently.

Is there a way to set front-to-back precedence or display order or 
something for the web controls?  Is this a result of my code-behind 
monkeying with the web controls and as a result forcing them to be "in 
front"?

Any ideas?
