title: Laravel : having the same element on each of my pages
body: <p>On Laravel 5.2, I'm trying to put two menus (X latest contents, and the same for a specific user) on near every page.</p>
  
  <p>The lazy way would be to generate those arrays in each of the controllers, but is there a way to generate it when the templating system needs them ?</p>
  
  <p>For instance, my template could call something like <code>{{ $menu }}</code> and the menu would be generated only when this was present ?</p>
