I would love it if you could add the ability to span relationships - please see the same issue report in the predecessor of this package (django-admin-autocomplete-list-filter) for info

hmm... dalf uses built-in list filters by default. like regular;

list_filter = ['foo__bar__baz']

should also work. i'll check on it. keep you posted.

ok, i've seen the problem :)

the problem is related to builtin ajax autocomplete view. only completes foreign keys. i'll investigate how to implement this feature. i don't want to override django's builtin views. i'll see what i can do.

vigo commented 3 weeks ago 
list_filter = [('foo_bar_baz', DALFRelatedField)]

works. only DALFRelatedFieldAjax doesn't work due to built-in auto complete view.

Yeah, that's the same point I got to. I will see if I can figure out how to change it myself - thanks.

i want to implement it, seems a bit challenging. my main goal was to use all the built-ins shipped with django and kind of wrap around w/o adding or tweaking anything as less as much i can. i'll try to to implement a class which inherits from existing AutocompleView and all i need is to intercept queryset. builtin autocomplete view checks the field's existence. in foo_bar_baz there is no field in the model. view designed to work with FK and M2M fields. I'll try to implement it :) Maybe someone help me out? all PR's are welcome :)

I found this Stackoverflow answer that may be a good starting point. It's a couple of years old though.
