django-admin-numeric-filter
django-admin-numeric-filter provides you several filter classes for Django admin which you can use to filter results in change list. It works in list_filter when a field name is defined as list where the first value is field name and second one is custom filter class (you can find classes below).
Don't forget to inherit your model admin from admin_actions.admin.NumericFilterModelAdmin to load custom CSS styles and JavaScript files declared in inner Media class.
