AEM Form Design Structure Issue

@arjunram  I would like to add to what @kosta_prokopiu1 said. You have a form design with a flat hierarchy and you want to have a nested structure, this is not possible unless you create a similar structure in the hierarchy.

If you notice the schema in the binding tab gives you a good idea that what should be created as a subform. Let's assume you do the binding without subform as is then you will be able to get the data but the challenge will come in if the schema has further nested objects or there are repeatable sections. I cannot comment on how it would conform to the schema you can test it once. So based on my experience below are the  suggestion:

1. Bind the form with the schema as is and see if with little refactoring you can get it to work. Maybe some sub-forms would be required.(50-50 chance)

2. Long-term solution, redesign hierarchy as per schema.(100% efficient) 

@kosta_prokopiu1 @mayank_gandhi Thank you for you response.

I have already form designed and live in production.

So we cannot redesign, I have tried binding form without subform as is to scheme, I have few scenarios  which turnout to be blockers.

1. repeated section on form and since there are no subforms I am unable to bind to *.

2. There are two instances of object already on as [abc0], [abc1]. Then how to bind these things on schema. Because I do not have subform where I can mark as *.

Thank you
