Mini cart does not open when clicking my custom button #

Confirm the element has the class showMiniCart exactly (case-sensitive). Also check the browser console for JavaScript errors – the mini cart JS file (dp-add-to-cart.js) is only loaded outside the Bricks Builder editor preview.

Add to cart button does not trigger the mini cart #

Your button needs both add_to_cart_button and ajax_add_to_cart classes, plus data-product_id and data-product_type attributes. Check that WooCommerce AJAX is enabled under WooCommerce → Settings → Advanced.
