Do I need to fill out everything?

I am not sure if I have understood your question correctly. Are you trying to fill out any form?

I did check your account and found that you have built one form. If you want your users to fill in all fields, you need to set all questions a required question. If you want to have few questions as optional, then you do not have to set those fields as a required field. The following guide should help you how to set fields are required: https://www.jotform.com/help/546-how-to-set-a-field-as-required-or-non-required

Hope this helps.

If you meant to ask something else, please explain your question a bit more in detail, and we will try to help you.

We will wait for your response.
