I would like to show the order summary by default in the checkout page , Can someone help me with that?
The order summary should be showing by default on the checkout page, in fact, you can't really edit that checkout page without being on Shopify Plus. Do you have a screenshot to show what you mean?
Actually our store is in shopify plus and I want the order summary to be opened by default. when I click the show order summary toggle , I should see the product line items
