title: How to create a simple divider in the new NavigationView?
body: <p>Google introduced the <code>NavigationView</code> in the Design Support Library version 22.2.0 with which you can create a drawer very easily using a menu resource.</p>
  
  <p>How can I create a simple divider line between two items? Grouping the items didn't work. Creating a sub items section does create a divider line, but it requires a title, which I don't want.</p>
  
  <p>Any help would be appreciated.</p>
