Once you have created your Form Template (see Create a Form Template if you have not created one yet) and are happy with how it looks, you will need to Publish it so it can be used to create Forms in Content Manager.
You will not be able to find the Form Template while it is in DRAFT mode.
Click on the Details tab.
Click on the Publish button at the bottom of the screen.
Click on Confirm in the popup window.
The Form Template will now be published and available for use.
