Products that have mandatory options can be a dinner deal in which a customer must choose between dinner preferences such as fish, meat or vegetarian.
Can also be used for extra optional options, such as an entrance ticket to an attraction with a souvenir as an extra option.
Optional extra options are not necessary to be sent in the booking request for the order to be completed, mandatory options, on the other hand, must be present in the booking request for the order not to fail.
This is as an example of mandatory options.
