I would like to separate my app’s models in the admin index:
I registered all my models in admin.py and I get all of them in the default admin index under the big red 1 shown below.
Now I’d like to have some of my models in another “block”, as shown below under the big red 2.
To make it harder, I also need to have some models in both “blocks”, but with different queryset.
How can I do that?

I tested my solution and it works.
Do this:
UPDATE:
To achieve your goal (max flexibility) , you will need to modify the template
admin/app_index.htmland the viewdjango.contrib.admin.sites.app_indexto your own needs.
