How do I share my forms with my team before publishing?

How do i share my forms with my team and they with me for collaboration purposes

We have a collaboration feature, guide here https://www.jotform.com/help/419-Understanding-Form-Collaboration. Once you share the collaboration link to your colleagues, and they clicked on it, you should see their name at the top-right side of the screen. This is for editing the form.

If you do not want them to edit the form, and only view its fields or layout/design, go to the Publish tab and copy/paste the link to your colleague.
