If you use a jquery menu solution of some kind (there are other ones besides nice menus, which is primarily CSS driven), you should be able to alter a couple lines of .js and you'll be done. All you need to do is change any hover actions to onclick actions. At least that's my initial thought.
You may want to check out the code in this one as a starting point (especially if you're on D5).
Good luck!
Hi all! I've been trying to come up with a solution to implement a clickable drop down menu system for a site. Something similar to Nice Menus but I do not want hover to do anything, I only want the levels to expand on click. I can't believe that this is not something that has been put into a module before. Basically what I want is something like the menus on digg.com . Does anyone have any ideas on modules for this or should I just start writing my own js now? lol
