Mega Menu Addon

In it's present form all categories are displayed under a single nav tab. Before it is commercially available, I would like to add support for selecting individual categories to subsequent tabs along with brands support.

I have added Featured Products support as you can see in current demo

I know this has been a while but I am looking for something simular for v4.03.

Im looking for the same type of menu system but for a verticle menu. The example I have of my sites current state is and I would like the side menu/categories to function like they do on

Looking forward to hearing from you, Thanks.
