According to WordPress documentation, by default, clicking the .more-link anchor opens the web document and scrolls the page to section of the document containing the named anchor (#more-XXX). This section is where writers choose to place the  tag within a post type. With this plugin we can prevent this scroll down.

This plugin requires <a href="https://wordpress.org/plugins/woocommerce/" title="WooCommerce" rel="ugc">WooCommerce</a>. It allows the site owner to prevent a product from being purchased by enabling a checkbox. It also allows you to override the message on a per-product basis. This will be useful for when you want to let customers know a product is only available in-store but still have the product listed on your website.
How does it work?
This is a very simple plugin that hooks into WooCommerce’s woocommerce_is_purchasable filter. When a product is deemed unpurchasable the “add to cart” button on the main product listing is replaced with a “read more” button. When the customer views the single product page they are shown a message that the product is not available for purchase and the add to cart buttons are removed.
