Hi, I used a package exclusive for admin, it call django-select2-admin and it's magic. Only register in installed apps and that's all.

Regards.

Okay so there is no need to go to different websites if you want to install a Python module. You will find almost everything related to Python modules in pypi.org, it includes everything like installation instructions, gut repo for the packages etc

Hi again,

The package is this : pip install django-admin-select2

It didn't have docs, just the git page (django-admin-select2) with a readme, its really easy, does all you need but you cant customize.

Regards.
