There is still a problem with filtering in selectize widget.

If I set max_prefetch_choices to a value less than the number of possible choices - in this case everything works as it should, but it is extremely inconvenient when I add new values in these same forms.

If max_prefetch_choices is set to a value greater than the number of choices, then filter_by does not work.

Maybe I'm doing something wrong?

In the Selectize widget changed quite a lot of settings. Please checkout the branch releases/2.0.x and check if it has been fixed there.

I use the last pip version. 2.0.1. in my project.
I use Selectize widget with search_lookup='name__icontains' and filter_by={'cafe': 'cafe_fk__id'}
and filter_by works only in case that max_prefetch_choices is less than number of choises.

I used testapp Version 2.0rc2 and I just set max_prefetch_choices to 250000 and after it StateFilteredForm show all County from all States... I think it's wrong isn't it?

I've just founded your fix in 2.1 fix: fields using a filter are always considered as incomplete of this problem. Thank you!
