After tinkering for hours i discovered how to have a fully expanded category tree on the drop down. All css, no category generator(s).
Now you can hover over the level 1 top category, the menu drops down and you now have a category menu with all of the categories, sub categories and their sub categories expanded.
I'll provide a link to a test site of mine with this working for anyone interested, please remember i have'nt started to style this yet but basicly you can have any width etc etc, but i will update when i have done some more work on it.
