Well i listened to all you guys out there in my forum and my blog and now all those wishes have been granted!
Haha! Like there was one. Well there was, but only for Rico and a bloated one by mootools, that is right I said bloated, live with it. For some reason there wasn0t one for scriptaculous but now there is. The why is pretty simple, just like every other library, I had a need for it. Hope you can get some use out of it.
Oh, by the way, not only does this script handle vertical accordions, but horizontal as well!
