I'm using checkout.twig in the CraftCMS shop checkout examples templates.
As the user proceeds though the checkout process, this nav strip appears at the top of each page and marks their progress. The nav strip is active and so the user can bypass the shipping section altogether by clicking the "Payment" link at the end and then just pay for the item and not pay any shipping. The shipping doesn't get applied automatically as they should go through to the shipping section and click the shipping option radio button. I would much sooner automatically apply the shipping without them having to select it. Can anyone tell me how to automatically apply shipping and also prevent the user from skipping ahead by clicking the payment button?
Thanks.
