Hello,
Well, can you help me at least to show in the floating cart so with the scroll that all the products that the customer is uploading to their cart are displayed
Provide us with WP Dashboard and FTP access to your site and we’ll try to remove the limit for the off-canvas cart and add scroll.
To enable percentage discount go to Theme Options > WooCommerce > Shop elements > Sale & Out of stock > enable percentage discount option.
