Comment ajouter des options de livraison dans ma boutique en ligne ?

You can add delivery options in the Content panel of the ST100 block, "Shopping cart with an order form".

Open the Content menu → Input Fields → Add input field → and select the Delivery variants field type.

List the delivery options, separating them with a line break. If the delivery option is not free, add the "=" sign and specify the price (numbers only, no currency).

The option to select a delivery variant will appear in the shopping cart. Delivery price will be added to the price of the product.
