Reply To: How do I collapse the review section for a single product?

Hello woshiyixiuge915,

Thanks for your patience.

You can enable this pagination in Dashboard > Theme settings > Single product > Gallery > Main carousel with pagination.

In order to hide arrows, Please add the below Custom CSS code to Theme Settings > Custom CSS > Global Custom CSS:

.woocommerce-product-gallery .wd-nav-arrows.wd-pos-sep {
    display: none;
}

Best Regards.
