Hi Reiss,
I will add the jquery and jqueryui javascript to the solution today so its available for use.
I also recently added YUI, which I think has a lot to offer. I'm using the YUI tabs in my product display. The interesting thing is I just include some scripts in the page and I'm able to create tabs right in the FCKeditor using source view. I mean they don't display as tabs within the editor itself, but when you save it it works. This is kind of nice and quite a different thing than creating .NET wrapper controls (which I will probably also do).
Cheers,
Joe
