We offer different default menu styles:

<menu>
  <!-- list, grid, drawer, tabs -->
  <mode>grid</mode>
  <!-- shows the group name -->
  <grouped>true</grouped>
  <!-- show group only if more than 1 group exists -->
  <group_only_on_multiple>false</group_only_on_multiple>
</menu>

If you use drawer the main area of your application won't show the menu, instead it's only available as overlay/hamburger menu.
