Is it possible to populate a repeater field from another field in that row?
e.g. A drop down of values from an options page, when one is selected a default icon from the ACF Font Awesome field automatically populates.
Even though this is a text field this gives you an idea: https://share.getcloudapp.com/6qu2W4vZ.
Doing some research I found a lot of people referencing the afc/load_field but not quite sure if that is correct or how to implement it.
Any help would be great, thanks.
acf/load_field is not the correct thing to use here. This does the work in PHP. It could be done but that would mean making the selection and saving the post to have the other field updated.
