How to load data from a garter in django-admin?

Question

Django

There are countries . Every country has its cities. It is necessary to make it so that when a user selects a country in the admin panel, his cities are automatically loaded into another select (html tag).
In general, this option is not good for me:
models.py

class Slider(models.Model):
    country = models.ForeignKey(Country, verbose_name="Страна")
    city = models.ForeignKey(City, verbose_name="Город")
    description = models.TextField(verbose_name="Описание тура")
    status = models.BooleanField(verbose_name="Статус")

or create an empty select in forms.py and intercept the change_form.html template so that it can be loaded there via ajax into the empty select created in forms.py
Are there any other ways to do this?
