In OutSystems, which property determines whether an Input widget is mandatory?

The property that determines whether an Input widget is mandatory in OutSystems is the "Required" property. When this property is set to true, it signifies that the field must be filled out by the user before they can submit the form. This functionality ensures that all necessary data is collected and helps maintain data integrity within the application. If a user tries to submit the form without providing a value for a required field, they typically receive a validation message prompting them to complete that input.

The other properties serve different purposes: "Visible" controls whether the input is displayed to the user, "Editable" determines if the user can modify the content of the input field, and "Placeholder" provides a hint or example text that appears within the input field when it is empty but is not related to the mandatory nature of the input.
