I am creating a webshop with 4000 products, with 60 attributes per product.
Each product contains only 20-25 attributes, there is no value for all of them.
I would like the attribute label and value, which value is empty, not to be displayed on the product page.
All products are single-product.
Can someone help me with this? What php code is needed?

I’d like, only attributes with a value should be visible.
