Lets say I have a group of fields containing three fields "fielda", "fieldb" and "fieldc".
Is there a way to assign a unique css id or class to each field when it's cloned? eg: if the group is cloned four times, fielda will have the following css class or ids for each field: 'class-fielda-01', 'class-fielda-02', 'class-fielda-03', 'class-fielda04'.
Why Do I Need This?
So that I can uniquely reference the field inside of a group using JS to trigger a change in another field inside the same group. Right now, if I try to do that with just the current css class/id options, the field in all groups will be changed because there's no way to uniquely identify the field in current group.
Currently, this feature is not supported for the subfields in a cloneable group. You can try to use the selector following this format group_id[index][field_id] to select the subfield by input name. The index starts from 0, like array keys.
