The first step in using Sintel Forms is to choose whether you want to
Create a form using a new list
Create a form using an existing list
Choosing "Create/Edit a Form" will prompt you to confirm if you want to create a new list or use an existing one and once you have chosen an option, you will be re-directed into the Designer.
Creating a form using a new list
If you choose to create a form and then choose to create a new list you will be prompted to enter the title of the list, this should be unique.
You can always change the display text of a field to more suitable one by either changing its title directly within the SharePoint list or within the layout screen in the Sintel Forms designer.
Creating a form using an existing list
If you choose the "Use existing list" option then you can select the list you want to configure and after clicking "Next" you will be navigated to the Sintel Forms Designer.
To use Sintel Forms Studio to design forms within a SharePoint site you must have the "Manage Lists" permission on the particular site. If you don't have this permission the options to "Create form" and "Import a form template" buttons will be disabled. This permission is available with the Edit, Design and Full Control permission levels and we recommend that you grant users this access by placing them into a SharePoint group that has that permission level applied to it.
Many of our customers actually create a specific SharePoint group for this purpose calling it "Sintel Forms Designers" and applying the "Edit" permission level to it. This restricts the use of the Sintel Forms Designer to a limited number of users so that only a select few have the ability to design forms which helps ensure consistency of form design across an organisation.
