What are the values ​​of ModelSelect2Widget, django_select2 arguments?

Question

Django

I want to use ModelSelect2Widget for dependent dropdowns. But I can't understand what values ​​the following arguments should give and what they are for:
* search_fields=['region_id'],
* dependent_fields={'region': 'region'}.
I just know dependent_fields for dependency. Can you explain it?

The example shows what is what.
search_fields - model fields to search for input text
dependent_fields - keys - name of the form field that triggers recalculation, values ​​- names of the model field for filtering.
