django-admin-list-filter-dropdown
A Django admin filter implementation that renders as a dropdown.
If you have more than ten values for a field that you want to filter by in Django admin, the filtering sidebar gets long, cluttered and hard to use.
This app contains the DropdownFilter class that renders as a drop-down in the
filtering sidebar to avoid this problem.

pip install django-admin-list-filter-dropdownEnable in settings.py:
