Tabstrip 2 - how to use in HTMLB?

In my EP5 SP5 portal, the Style Edtor shows a control called a "Tabstrip 2" which is exactly the kind of look-and-feel I want to use in an iView I'm developing.

Since HTMLB only documents the basic "Tabstrip" control, I was wondering if anyone knows how I can use a Tabstrip 2 control instead?

Thanks in advance,
