How to show unanswered/answered fields at the last page before they submit the form?

Hi

Once I have done my form and submitted and lets say a person has completed filling it in

how can I save/publish it in such a way that even unfilled fields are shown in the final form 

did not find my answer

You can add "Preview before submit" widget to your forms if you want to show the answered/unanswered fields in your form.
