I want to hide some fields after click on ad_type(choice) field.

回答1:

Best way is to use form media to add an external javascript file that will listen to the change event of the field ad_type and perform the action you need.

In this case you will need little python and lot more of js, but I think is the clean way.

To add the external js file use the class Media, this answer to another question shows a practical example.

Than you just have to have fun with writing js code, you can use the jQuery already included in django admin.

Hope this helps
