Shopping Cart – Documentation
By adding a Shopping Cart field on your website or form, in combination with a Product field, you allow your users to perform online payments.
The Shopping Cart field itself has no custom properties excepting the standard field set of properties.
To be noted, that if the “Required” setting inside the “Validation” field of properties is set to “YES”, then form submission is not allowed in case the user did not added something in it’s shopping cart.
