Using the acf_add_local_field_group( $field_group ) function, I’m able to register a field group successfully which populates with the right data in the admin.
I’m trying to get the resulting data ordered/sorted by a specific field, but there isn’t documentation around this in either the Group settings, Field settings, or Relationship Field settings. See: https://www.advancedcustomfields.com/resources/register-fields-via-php/
Is this even possible to do?
