Validation
The first check mark next to the form widget is the validation rule. You can use this item to add a validation to your interaction page. When you add a validation rule you are prompted with the expression editor. Here you add the expression that should be validated. The validation rule overrides the ignore user input and will always be checked when leaving a node through a button exit.
