Generate a tabbed submenu — from taxonomy term or submenu item — with sample content

I ended up solving this problem with Ubermenu.

What I wanted to write was complex enough that it made more sense to get a tested, commercial plugin that had the features I need. MaxMegaMenu didn’t do tabbed content but Ubermenu does.

I’m able to construct menus like this:

Taxonomy1
  [Tabs]
    [DynamicTerms]
      [Dynamic Posts]
Taxonomy2
  [Tabs]
    [DynamicTerms]
      [Dynamic Posts]

etc. The end result looks great, it integrated well enough with my custom theme (though I had to convert their LESS to SASS for Foundation compatibility), it does sticky and mobile menus as well, and it’s well supported.
