Custom Related Products for WooCommerce lets you choose which products should show in the related products area on a product detail page instead of simply showing products from the same category. This plugin has been tested with WooCommerce from version 2.1 to 3.0.
The master branch of this repository is intended to reflect the stable and current version of the plugin, however it is recommended that you install the plugin from your dashboard or from the WordPress plugin directory to ensure you always have the official release.
