The Submissions section contains a separate sub-section for every form created in the system.

Each of the sub-sections displays the lists of form submissions. The columns in the list depend on the form fields you have selected to be displayed in the grid. The only columns constantly displayed on the submissions list are the ID (form submission number) field and the Submitted On (date/time) field.
Double click the form submission to view all the form fields in detail.
