Une question au sujet d'une fonction de la version 6.6.0

Bonjour,

j'ai analysé le fichier log de la version 6.6.0.

J'ai lu ce paragraphe :
"The "Product page" menu item type can now carry the whole checkout on the page itself, so that a customer orders without ever leaving the product. A new "One page checkout" tab on the menu item turns it on and gives you the list of checkout blocks displayed under the product, with the same drag and drop editor as the checkout of your configuration, but for this page only: the checkout of the rest of your shop is not affected. The page opens with the product already counted in, showing its price, its taxes, its shipping cost and its total, without anything being written in your database until the customer actually orders something, so a visitor who only looks at the page does not leave an abandoned cart behind. Changing the quantity, the options or the custom fields of the product updates the totals, the shipping methods and the payment methods on the spot, without reloading the page, and there is no "Add to cart" button to press. Your customers are identified as guests, with their email address and their delivery address asked directly on the page, unless they are already logged in, in which case nothing is asked of them. The order button, whose text you can change, creates the order and sends the customer to the payment as usual. This is available in the Essential and Business editions."

Pouvez-vous me dire comment mettre en place cette fonction? J'ai cherché et je n'ai pas trouvé.

Merci pour votre aide

Sincèrement,
A. Guillen
