I accidentally posted this in the design forum, so I'm reposting it here.
Someone might want to correct me on this, but I believe I have found a bug in rich:dropdownmenu in IE 7 while using CSS positioning (non-static). What happens is when you use CSS to position items using all but static positioning in IE 7, the dropdownmenu will appear BEHIND a component below it which has anything but static (default) positioning. This works fine in Firefox 3 (the menu appears in FRONT of the element below it).
My environment ( I have tried to make this test case as simple as possible):
Richfaces 3.2.2.GA (and whatever version of Ajax4java comes with that)
I've worked around it, but I just thought maybe the developers would want to know about it.
Here is a very simple example page to illustrate the problem:
