Hello Harshit,
You could think about more front end configurable Feedback form for example what you can do is the following:
Feedback Template
Title
Description
1-* Feedback Template Questions
Sequence
Title
Description
Comment field
Then when you create a feedback you can select the template and based on the template you create a feedbackform entity
Feedback Template 1 - * Feedback form
and then you create based on the Template questions the form questions
Form Template question 1 - * form question(add here an attribute to but the comment in)
Feedback form 1-* form questions
Ofcourse you can make many more adjustement if you would like, but in this way you do not need to hard code all your questions and comment fields.
Hope this helps you on the way,
Good luck!
