What's the widget used to assign user permissions in Django admin called?

Question

What's the name of the widget that we use to assign user permission in admin page (under the "add users" option)?

How can I use it for other things?

Answer 1

It sounds like you are talking about filter_horizontal.

To use it, add this to your admin config for each model you want to use it:

filter_horizontal = ('field1', 'field2',)

See the docs.
