Chained select Django admin cascade dropdownlist

So many different order nested select boxes. Where for example we have to select Brand of a car then a type of a car.

If you select a brand "BMW" then in subselect only BMW models will appear.

Searched a bit further and this one looks better.

Many people use this application and very nice stackoverflow post.

Yes, read code from an admin and model this example.

Looks good.

This application has been recently updated and works with a recent version of Django.

Only URL pattern is in my opinion a bit strange 
 

re_path(r"^chaining/", include("smart_selects.urls")), 

 

I expected something different and had to search a bit during installation.

Otherwise default installation procedure from document works completely and without problems.

Model looks simple and doesn't need any forms or Admin adjustments everything works like magic.
