@mapleflow can you explain in detail about the approach you used?

I know that django-jet is not maintained any longer but this is the approach I use to have multiple choice filtering in the jet admin: https://github.com/pierreben/django-jet/commit/3e376a5b9df549d4bf4b6fa609a4120681e657a5.

To use it, you have to create a custom filter in your modeladmin inheriting from MultipleChoiceListFilter:

from jet.filters import MultipleChoiceListFilter

class RegionsListFilter(MultipleChoiceListFilter):
    title = "Région"
    parameter_name = "regions__in"

    def lookups(self, request, model_admin):
        return FRENCH_REGIONS_CHOICES

If some people are interested, I can submit a pr for this.
