The Options Tab allows you to choose which options are part of the option set. You can add options form the drop down menu and reorder the options with the arrows on the right side.
By default options will be set to required. Uncheck the required box to make it optional.
Multi Select Options
If you have configured a multi select option that has a restriction to allow zero selected options, be sure to uncheck Required. Failing uncheck required for this type of option will mean a user still needs to check at least one option.
