I'm using Magento 2 and I've noticed that on the related products block , on the product page , the add to cart button for the related products is actually a check box, and not a properly button.. is there any setting for that to be a properly button ?
By default Magento, there is no setting option in Admin for Add to Cart button on the related products block. If we want to custom the related, upsell, crosssel and new product template, we should override this template
$showCart = true; in case - related product.
We can refer here: Related Products template customize
