Thank you, John. You’ve confirmed my concerns – there’s no JS API.
So I will probably update custom field value via AJAX, but I still need some way to re-render the field group with updated values – so basically I need to know how ACF handles field group rendering.
I’m almost sure that it is possible (even if it’s not documented) because this is what happens if a field group is shown conditionally (for example if a field group is assigned to a specific page template and show/hides depending on a chosen page template).
TL;DR
I’d like to know how to call a field group re-render (or even better – a single field re-render) with JS.
Thanks.
