Is there a way to select more than one option in django admin filters?
For your first question:
I think it's possible. I've made a quick test on the admin interface for Users, and if you play with the URL querystring, you can combine filters : /admin/auth/user/?is_superuser=1&is_superuser=0 will list both super and non-super users.
You'll have to override admin filters template to generate proper URLs for your needs, though.
I don't understand your second question. What do you mean by combined ? If you select an item in the first filter and an item in the second one, you will have combined filtering, won't you ?
I actually have two questions, please answer what you can:
Question 1:
In django admin, if you have list_filters = ["book"], and your options were "red carpet" & "Bingo the Dinosaur", you can only select one book at a time; either "red carpet" or "Bingo the Dinosaur". Is there a way to make it so that the user can select both at the same time?
Question 2:
In django admin is there a way to combine list_filter fields? so if you have list_filer = [" bookname", "bookauthor"], is there a way to make it so that the book name and author are combined in one filter and you search it at the same time?
