Product forms
Liquid Ajax Cart ajaxifies Shopify product forms once it is loaded. When a user submits a product form, Liquid Ajax Cart intercepts the submission and sends a Shopify Cart API “Add to cart” request.
The form remains inactive when the “Add to cart” request is in progress and Liquid Ajax Cart adds the js-ajax-cart-form-in-progress CSS class to the form.
Add a container with the data-ajax-cart-messages attribute with the form value within product forms to show error messages.
