Hey There,
The example site is not using any tabbed contents. It is actually using different pages with a custom menu in it.
All Campuses displays the Campuses Overview page which is the parent page of all the campus pages. And then in each of the pages, he created a custom menu and add it before the contents of each pages.
You can recreate this in your site using X if you want to. Just set up the pages first. You can then go to Appearance > menu, create your custom menu and add the pages as your menu items. You may insert the menu is each of the pages and we can then add some minor cosmetics for the menu.
Hope this helps. Please let us know how it goes.
