Sub mega menus

Hello, is there a way to create some kind of menu structure that will allow layered mega menus? I want to be able to create a top level full width menu with text links which by clicking on a link triggers another sub menu. I’m interested in buying and not sure if this would work.

Maybe the tabs option will do it, however i’d want the tab to not be open on initial drop until clicked. Is this possible?

Thanks
Glen
