Implementing Superfish MegaMenu?

I found an old post for D6 where you mention Danland might support Supefish's multi-column menu (I assume that's what megamenu means). I have Danland 7.x-1.0 and Superfish 7.x-1.8 installed (which says it supports megamenu). Do you happen to know how to make that work? Or can you suggest an alternate multi-column module?

Thanks for a great theme, BTW. It's gotten a lot of oohs and aahs with just a little extra styling that was very easy to do.
