Thanks John, in this case I think the simplest way is leave the parent title field blank and write it into the field description instead. In the cloned field the parent description field can be hide using css display: none
I have 15 field groups, approximately 10 parent field for each group and 3/4 child field for each parent field. It will take a bit of time so I was looking for an easiest solution, but I can do it 🙂
