I forgot to say I am using DW CS3 and on a mac if it matters.
I have updated my spry to 1.6.1 if that matters also.
A good non-Spry tutorial:
There are also plenty of tutorials via Google for creating Spry dropdowns. I personally never use Spry. No particular reason for that. I just have other methods.
My favourite commercial product for high quality menus. Easy to create, modify and maintain.
(I have no link to them. Just a happy customer passing on a link).
My vote is for PVII also. I started with Spry a little bit. Too much coding for any basic user and Spry development has fallen off the radar with no anticipated update for CS5. 100% PVII is the way to go.
