Lists are like the rows or columns of a spreadsheet, you can have more than one list present inside a module. In the above pic, there is one list "Policy Number" which is present in the row of the module "Nominee Location Amount Check".

Lists are used to group the related items together & you can place them in row, column or as a page selector. For example, we can place all policy number inside one list or we can have name of all the employees inside one employee list etc.
