How to make field require or un-required?

I have a form where each question is mandatory.  Right now, users cannot move to the next question until they fill out all of the required fields.  

Is there a way to make a form with all mandatory question where the user can skip questions and then come back to them before submitting? 

Thanks!

Yes Jotform has feature you can use to make a form field(s) "required" based on how a user has answered a certain question .

Below is a guide on how you can use this feature:

In your case I would also suggest you use the skip page condition too:
