Creating a hidden form
A hidden form will not be displayed in your public facing form list, and will only be accessible via a direct link. To make a form hidden, simply click on the form in your form list. Check the "hidden" box:
Once you have saved the form, you can copy the direct link by clicking the link icon in the form list:
Note: a hidden form must be marked Live and its expiration date must either be current (or removed/blank) for any submitter to be able to access and complete it. The Live checkbox can be found in the General Settings tab.
