title: Drupal List of related views
body: <p>I need to list all the projects of an advertising company with their pictures and videos grouped by subject.
  For example, list under "Green Campaigns", all the projects related to that one, and at the same time, under each project show (using a grid) all the pictures and videos of that specific project.
  My approach was to make a different view for each listing, but I cannot attach a view inside another view.</p>
  
  <p>I created a content type for the pictures, the projects and subjects. Each making references to each other. (this part is working)</p>
