Hi @puppamReddy
I think the issue might be too big from. I think you should implement it in a different way e.g:
Put Entitlemens in a list or map and. Do a multivalue field with entitlement names. This will result in a dropdown list for user to select entitlement. You can add dynamic field with with description. After editing, user can submit changes and then you can update entitlement and show again the same form.
