Hello John
I was able to use successfully your other post :
https://github.com/Hube2/acf-dynamic-ajax-select-example/tree/master/dynamic-fields-on-relationship
My problem now, is to populate some fields (example: title, image …) but not from 1 post but from 2 different posts.
I try to not use a relationship field but instead use a post object field, do you have an example with 2 objects field ?
Concerning the example above, do you have a json field group to test with it ?
Thank you for your help
