The Submissions menu option allows (if you have the permissions) to view all submissions to the form selected. You can view this in one of two was by list view or by table view.
List view shows the submission in a list with the following headings;
Form Name
Created By
Created At Date and Time
Last Viewed By
This view can also be filtered by latest submissions and also can be searched using the search bar.
Table view displays the submissions in the form of a table, similarly to how a .CSV file would. You can see the information in line with how the form is created utilising the elements as headings within the table. The Table will differ depending on the elements used. You can search for data in this view by using the search bar.
