I have added a page viewer webpart and pointed it to a network share. The top navigation menu now hides behind this webpart.
I have tried setting the z-index on the menu container as well as the webpart div container. Nothing that I have tried seems to work. Has anyone run into this?
ActiveX components (which is what you get rendering a network drive) is always on top of HTML, z-index or not. You cannot do anything about that in Internet Explorer (except having a script that temporarily hides the ActiveX while you're activating your menu).
An network share is displayed using an ActiveX control (explorer view), which always render on top of everything.
