"Tabs" work very nicely. Simple user interface. I am using them inside Virtuemart product descriptions. The new release (Version 3.2.5) fixes an issue I had with the earlier release, and provides backward compatibility. I had one remaining concern about the behaviour of "tablinks" (linking to an existing tab from elsewhere in your content), but Peter (the owner) produced a fix and emailed it to me within 24 hours of drawing his attention to the problem! Superb support, and that was for the free version!
