title: Django Admin Template Overriding: Displaying checkboxselectmultiple widget
body: <p>Have 2 tables Domain and Group having one to many relationship.
  These tables have many to many relationship with User table</p>
  
  <p>On the User admin interface I am rendering the Group and Domain as CheckboxSelectMultiple 
  widgets.</p>
  
  <p>Is it possible to present this in a table form with 2 columns: Domain in one column and the list of groups belonging to the domain in the other column.</p>
  
  <p>I want to override the fieldset template of the admin. However I am having difficulties knowing which methods/properties I can use with an AdminField.</p>
  
  <p>Thanks</p>
