Hi @rudtek
I’m afraid I don’t understand your setup, so forgive me if I’m wrong. If you want to load the choices of a field dynamically from another field without reloading the page, then you need to use AJAX. This page should give you more idea about it: https://www.bobz.co/dynamically-populate-select-fields-choice-in-advanced-custom-fields/.
I’m afraid I can’t give you any advice regarding the repeater method because I don’t know your setup exactly. Could you please share some screenshots of it? Also, please share the JSON or XML export file of your field group too.
Thanks 🙂
