I was wondering how they made it possible to display more fields in the User page of the Django admin site.
If you create a new User you only have some basic fields to fill in, but if you reopen that user (edit mode) then you see a lot more fields to fill in.

I'm trying to achieve the same, I had a look at the `add_form.html` template but I can't really get my head around it. I guess I'm looking for a way of specifying different fields = [] sets based on the edit status of the document.

Thanks!
