I think you want kind of a dependent dropdown right?
select2_from_ajax content changing depending on your first selection?

@adbmdp you are right

Hi @developerpratika ,

In that case, there's no pre-built solution for you. I recommend you create a custom field type starting from the select2_from_ajax, and place some javascript there that sends the value of your first selection through the AJAX call.

You can then filter the results inside the CrudController method, using that variable.

Hope it helps. Cheers!
