✅

The implementation of that “add” button is actually admin-specific.

In simple terms, you may use the wrapper located in django.contrib.admin.widgets.RelatedFieldWidgetWrapper. Consider what django.contrib.admin.options does:

formfield.widget = widgets.RelatedFieldWidgetWrapper(
    formfield.widget, db_field.rel, self.admin_site,
    can_add_related=can_add_related)

But that requires you to use admin-specific objects, such as admin_site, the admin javascript ans css files and urls. I would recommend you build your own “Add” interface, even if based on this wrapper.
