I always thought that I ‘ve seen a MOSS site using cascading roll-over menu on the Top Navig bar, Heather explains how to activate it.
Just one thing to add: the site has to be with the Publishing Feature activated so that the “Show Pages” can be ticked.
Great tip ! (as long as you don’t fast-reast like I did as the first site REALLY needs a page to be created , even if not used)
