Hi Iuilian, I just had another go at achieving semi-transparency for all submenus, but alas IE seems to have outwitted me on this one. It simply refuses to apply any sort of transparency to elements whose parents already have a transparency filter applied to them. I tried everything I could think of. I wonder if there are any examples at all... ever... of a multi tiered menu with transparency that works in IE6 (I think IE7 would be the same too). If there was then we could see how it was done... I don't hold out much hope after my experiments - but I'd be delighted to be proven wrong!
It seems like your IE users will have to miss out on the semi-transparency. I'm miffed that we couldn't show IE who's boss on this one - sorry. Joel Birch.
