Using interactions, fields can have the ability to affect the visibility of another field or element on the canvas. Visibility will be determined by cases, which are listed in the Interactions pane.
Note: The custom screen executes each case from top to bottom, so if two cases contradict each other, the latter case will take precedent.
After saving an interaction on a field or element in the canvas, you can add more interactions to the same field or element by clicking the New button in the Interactions pane.
Note: A list field that has been turned into a radio button list using the radioButtonList property cannot be made required for interactions.
