To get the plus icon back, you need to wrap the field in a
RelatedFieldWidgetWrapper. Here's an example from my code--obviously,
you'll have to adapt it to fit your situation.
class CategoryChoiceField(forms.ModelChoiceField):
def __init__(self, *args, **kwargs):
super(CategoryChoiceField, self).__init__(*args, **kwargs)
self.widget = widgets.RelatedFieldWidgetWrapper(
widgets.CategorySelect(
categories=models.Category.objects.order_by('parent',
'list_order')),
models.Category._meta.get_field('parent').rel,
admin.site,
)
