vertical tabs inside popup/dialog

vertical tabs inside popup/dialog

I'm trying to achieve vertical tabs inside a facebox popup. I am able  to get it almost working with jquery-ui-1.8.1 but the problem is that once the popup has loaded and the tabs are displayed, i cannot click on them to change the content and tabs.

in case you are wondering, what I'm trying to achieve is a  popup like on ebay ->
http://www.google.com/url?sa=D&q=http://motors.shop.ebay.ca/BMW-/6006/i.html?Model=6-Series&_catref=1&_dmpt=US_Cars_Trucks&_fln=1&_ssov=1&_trksid=p3286.c0.m282&usg=AFQjCNEH2pO1hOXtLOYnO_OOfYC1wLogFg
if you click on "choose more" you will see a popup with tabs and different content on each.
Or the same as on Kijiji -> http://www.google.com/url?sa=D&q=http://montreal.kijiji.ca/f-cars-vehicles-cars-Owner-W0QQAQ5fForSaleByZownrQQCatIdZ174&usg=AFQjCNFAlaAacHmmTkZ5trQFpqoiw6Z8ww
. if you click on "view more options", you will see tabs with different content.

I've spent a lot of time without any luck :( maybe someone more experienced can guide me or maybe give me a very simple example of the a popup with tabs inside. I've also started a post on google group's facebox group here in case you want to read it: http://groups.google.com/group/facebox/browse_thread/thread/f5a2ea852a261761 . It doesn't have to be with facebox (i've seen that jquery UI has a dialog and it also has tabs but I could not get both working together) Thanks for your help!
