Reply To: Can I just hide some information of product at the single product page

Hello,

You can hide the breadcrumbs in the Theme Settings > Single Product > Show / Hide element.

In order to deactivate the attribute, navigate to Products > Attributes > enter the attribute and disable “Show attribute label on products”

Please add this code to the Theme Settings > Custom CSS > Global to hide the tags:

body.single .product_meta > span.tagged_in {
display:none;
}

Best Regards
