Types of forms
The following types of forms can be designed using Nintex for Office 365.
List forms (Start forms): The form used to add items to a SharePoint list. This forms designer is accessed from a SharePoint list or library. After a list form is published go to the list and click New item to open the published form. One list form exists per list.
Workflow task forms: The form displayed to users interacting with tasks assigned using the actions Assign a task and Start a task process. One task form exists per task action. Task forms are supported for both list and site workflows. For more information, see Design Workflow Forms.
