The Loop icon is for inserting lists of data. Clicking this will bring up an insert list popup.
Similar to the Variable insertion, you can select the list of data you wish to insert. The following options control how that list of data is displayed
Select the list attribute you want to perform a sort operation on.
Due Date - to sort by overdue invoices
Sort the attribute in Ascending or Descending order
using ASC with Due Date will show the most overdue invoices
Only show the first X results of the list after sorting
Limit to 10 will only show the top 10 overdue invoices.
When inserted you will see some control blocks appear in the editor, these consist of a
End block for your list.
Anything typed in between these blocks will be applied to each item of the list. To update the template filtering or list type, you can double click on the
For Each block to bring up the edit panel.
List Child Variables
When your cursor position is between a start and end block your toolbar should highlight the appropriate variable insertion buttons. Clicking that will bring up the variable insertion popup, however it will only display variables which can be output from an item in the list.
The same formats are available as for regular variables and work the same way. For more information, see the Using Variables page.
Once child variables have been inserted, you should see your live preview update with each records data replacing the variable placeholder.
