Unfortunately what you're referring to is the Mega Menu that comes with RokNavMenu 2.0. This was first implemented in the Zephyr template. As to porting to pre-Zephyr templates,Andy Miller wrote:
They are not automatically available in previous templates. number of reasons for that. 1, there is a change to the fusion menu layout, and also the fusion css. also there is new css to support the new possibilities located in the template's own css files. Of course these all could be ported to other templates, but it would take some time for each template. We'll endeavor to support these going forward though.
Just for numbers, a pretty skilled developer could probably port the additions to any other template in a couple of hours.
