What SharePoint list template types are supported by Nintex Forms?
All Forms for SharePoint on-premises
According to the first release notes found at https://community.nintex.com/docs/DOC-1156 (scroll to the bottom of the page) this is the list of unsupported types.
Designing custom list forms for the following is not supported:
• Nintex Workflow content types
• Document Sets
• Blog Post
• Blog Comment
• Discussion List
• InfoPath Form Library
• Event (not calendar event) Content Type (designer still enabled)
• Reservations (designer still enabled)
• Schedule (designer still enabled)
In addition, we are specifically prohibiting the following templates. This is because SharePoint doesn’t give us the necessary information to create the Form.
115 - XML Form library
120 - Custom grid for a list
108 - Discussion board
301 - Posts (Blog)
302 - Comments (Blog)
