I am not sure if you have tried autocomplete but it works well in unfold.

I would suggest to try it as this is more intuitive than raw id field. If you want try it, here is the quick/rough implementation. Thanks!

@admin.register(MODEL_NAME)
class SomeModelAdmin(admin.ModelAdmin):
    list_display = ....
    list_filter = ....
    autocomplete_fields = ("FIELD_NAME",)  <--- put the raw id field name here
