Problem with superfish submenu being trimmed by content in Firefox

Greetings, I have a problem which would seem to involve some kind of z-index issue,开发者_JS百科 but for a change it's in everything except IE.

If you take a look at http://cougar.motivo.com.au/ in anything except Internet Explorer and hover over the last menu item "Contact Us" you can see what I'm referring to. Basically the supersub menu appears to be being trimmed by the width of the element below it.

You can see via the source that I've tried setting z-indexes & position:relative, but at this point I'm stumped. Any and all input would be gratefully received :)

P.S. I am aware that there are still a couple of issues in IE6. I am yet to have the pleasure of addressing those (groans).

I think it's because the contact us menu is part of the page and as such is being trimmed when outside of it. if you put it higher, or use position: absolute and then place that should fix the issue.

can happen i guess if your, let's say div, is inside another. breaking the div out and moving it higher up will normally fix it.
