Thanks for the reply. I never could solve the issue with the menu falling behind the banner using the jquery plugin slideshow. I ended up using a flash plugin instead. Would rather use the jquery slideshow instead. If you think it is z-index, I might go back and try it.
Basically, both the drop down menu and slideshow using jquery used relative and absolute positioning. Think this may have been the conflict? I’m not sure what z-index is or zoom? are they related? the Dropdown UL had a zoom set to 1. I don’t know if the slideshow banner was using zoom. If you can shed some light on this I will retry with your recommendation.
