This would be a great Tab solution, but I wanted to use this with their very own Afterburner template, and it simply doesn't work. Requests for help on this issue in the RokTabs forum has gone completely unacknowledged since an initial request for more information. If it works for you, great. But if it won't work with one of *their* templates... not good.
Afterburner disables Mootools by default in its settings (Admin > Extensions > Template Manager > rt_afterburner_j15 > Enable Mootools : Yes).
And RokTabs requires mootools in order to work so just set this option to yes and it will work :)
