You can get more information from the customer with pre-defined questions. Predefined questions are required fields for the customer.
For example, even if you sell club t-shirts and there are several different colors to choose from, you can use a predefined question to create a menu from which the customer selects the desired shirt color. However, it should be noted that no product balance can be created for these alternatives, it should be done through product variations. You can also inquire about the customer's diet with a pre-defined question, for example, or if you arrange a bus trip to Saariselkä, you can ask the customer to choose a pick-up stop from certain options.
Instructions for creating predefined questions can be found here.
