title: yeoman angular-fullstack nav dropdown
body: <p>I have use the Yeoman angular-fullstack generator and absolutely love it!</p>
  
  <p>I'm trying to add a dropdown in the navbar.
  I found the navbar controller in Client/Components/Navbar/navbar.controller.js and added items to the menu object. This works fine for individual pages, however I cannot find any syntax on how to add a dropdown menu!</p>
  
  <p>I'm sure this is an easy question to answer but I am struggling to find any relevant documentation.</p>
  
  <p>Cheers</p>
