title: How To Collapse Just One Field in Django Admin?
body: <p>The django admin allows you to <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.fieldsets" rel="noreferrer">specify fieldsets</a>. You properly structure a tuple that groups different fields together. You can also specify classes for certain groups of fields. One of those classes is collapse, which will hide the field under a collapsable area. This is good for hiding rarely used or advanced fields to keep the UI clean.</p>
  
  <p>However, I have a situation where I want to hide just one lonesome field on many different apps. This will be a lot of typing to create a full fieldset specification in every admin.py file just to put one field into the collapsed area. It also creates a difficult maintenance situation because I will have to edit the fieldset every time I edit the associated model.</p>
  
  <p>I can easily exclude the field entirely using the <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.exclude" rel="noreferrer">exclude option</a>. I want something similar for collapse. Is this possible?</p>
