Hi Roxana, do you mean like a "Mega menu"?
I looked at the sony site, and it looks kinda like a mega menu-type.
Anyway read this post: showthread.php?t=25249, hope that will point you in some direction.
Els take a look at DMX Zones (www.dmxzone.com) "Universal CSS Navigation Menu" maybe that one is more spot on.
Regards
Morgan :)
