Checkboxes are used to allow the user to select one or more options of a limited number of choices. Based on the status of the checkbox a 0 (zero) or 1 (checked) is set as the value of the user input field. This value can be used in an expression in the PSM document to implement a specific condition (e.g. print or skip layouts). A data field can have only one checkbox, if a range of checkboxes is required one data field should be created per option.

Separator Line: Controls whether a separator line will be shown before this field. With this option web forms that have more complex variable data can be arranged more logically.
