title: Collapsible inlines in Django Admin
body: <p>Is there an up-to-date option for allowing collapsible inlines in the Django admin site?</p>
  
  <p>I've looked at <a href="https://code.djangoproject.com/ticket/494" rel="nofollow noreferrer">https://code.djangoproject.com/ticket/494</a>, <a href="https://stackoverflow.com/questions/2025597/how-to-add-collapse-to-a-django-stackedinline?rq=1">How to add &#39;collapse&#39; to a Django StackedInline</a> and Grappelli, but none of them seem to work for Django 1.6.1.</p>
  
  <p>Any suggestions?</p>
