I have a pop out menu using lists. The issue I am having is that I need the pop out to hover partly over the menu. I researched and added a z-index: to the pop out section. This worked great - or so I thought - only in FF not in IE. I cannot seem to find anywhere how to get around this by using CSS or otherwise- though I do only have limited knowledge. So currently when my menu pops out, part of it pops under the existing menu and makes it unusable. Any suggestions?
