Make a Question Optional Or Mandatory

You can control whether an individual question on an interview screen is mandatory or optional using behavior settings for the control. Mandatory questions will require an answer from the user before the screen can be submitted, whereas optional questions allow the user to leave the answer blank or answer uncertain.

You can configure a question to be:

• always mandatory (default behavior), or
• always optional, or
• mandatory if relevant to the investigation, or
• conditionally optional or mandatory.

When designing screens, bear in mind that the investigation will not necessarily need answers other than uncertain to any or all the questions on a screen. For more information, see Decide Whether to Allow Uncertainty In User Answers.

You can provide an indication to users that a field is mandatory or optional when they first visit a screen using an icon next to the question. For more information, see Change the Display of Mandatory Fields and Change the Display of Optional Fields.
