I propose the idea to narrow up the choices shown in list_filter, by those available among the "current" queryset's results.
Use case: In a Book-Author-Publisher model, when looking for a particular book in the "list" view, you may first filter them by the author's name. From now on, I'd rather have the "publisher" filter show only publishers which have published a book with that author. <https://lh6.googleusercontent.com/-8PBR3iQfKDo/UiEOTCgArqI/AAAAAAAAAMc/4fueqNsYiww/s1600/django_filter.png> Showing the "Bookless Publisher" in the filters is almost useless, and it'd be better omitted. Another alternative for achieving the same goal would be prioritizing the choices in the filter by the number of "hits" in the current queryset's result. That way, those having zero corresponding record will be thrown down the list. >From the implementation point of view, I have a hacked version of "AllValuesFieldListFilter" which does it right, although I think it may be done in a cleaner way, if someone knowing more about the code feels helpful.
