✅

If you define the field in the form you need to include the widget:

from django.contrib.admin.widgets import FilteredSelectMultiple

blocked_email_notifications = ModelMultipleChoiceField(
    queryset=EmailTemplate.objects.order_by('key'), 
    required=False,
    widget=FilteredSelectMultiple(
        verbose_name=EmailTemplate._meta.verbose_name,
        is_stacked=False))

is_stacked:

  • False: the lists are rendered side by side
  • True: the lists are rendered one underneath the other
