Django Search Function inside ForeignKey

[khashashin]

I have a class with huge amount of data and another class which should take the title value from this class. How can I add a search function to ForeignKey as you can see in following Image. Or does Django have a way to solve this problem? Thanks a lot!

I saw alrdy django-autocomplete-light but i don't have views, admin, templates etc. My app have only models and wagtail_hooks.

This guy have same problem wagtail/autocomplete.

from wagtail.api import APIField
