This fits into a category generally referred to as either “cascading selects”, “chained selects”, “dependent dropdowns” or some such mix to that effect.

See the post (and the related links) at [Django 5: Within the form, filter data with another field of the same form - #4 by KenWhitesell](https://forum.djangoproject.com/t/django-5-within-the-form-filter-data-with-another-field-of-the-same-form/29847/4). You might also want to look at [Django: how to choose from a list based on the previous selection?](https://forum.djangoproject.com/t/django-how-to-choose-from-a-list-based-on-the-previous-selection/9240) for an actual implementation. (You might also want to check out [djangopackages.org](http://djangopackages.org) for other options.)
