Line references are optional notes that you can add to individual products within your shopping cart before completing a purchase. These notes help personalize or clarify details about specific items in your order.
To get this feature, please make sure that in the Admin > Roles > Global, the "Show Line Reference" option is enabled.
Once enabled, any user with that role will see the line reference input field when viewing the cart.
The line reference will also be visible in the Summary section during checkout, allowing users to review the information before placing the order.
