Customers choose one or multiple options. 
Title: Format the title as a Label or Heading, or hide it.
Add description: Displays more information about the add-on underneath the heading.
Required field: Prevents product from being added to the cart if an option is not selected.
Options: Add a label for each option as well as a price if needed. Calculate the price as a flat fee regardless of quantity, per quantity ordered, or, charge a percentage of the total.
Note: You must add a Label for each option, so the information shows when viewing the order and is passed through in the confirmation email to the customer.
