unable to preview and share the form with team members before publishing

unable to preview the entire form without completing the required fields/completing the form

Hello,

First of all, please take a look at the following guide: https://www.jotform.com/help/419-Understanding-Form-Collaboration 

As far as I understand, you want to share the form with your team members in order to create the form altogether. So, you are using the collaboration link. However, I did not understand your second sentence "unable to preview the entire form without completing the required fields/completing the form" Could you please describe the issue further?

Thanks in advance.
