The idea of this plugin comes from the best opensource ecommerce platform after woocommerce : Magento really beats them all in terms of ease of administration, and the most interesting feature is the category tree hierarchy with products display : this plugin brings this magical feature to wordpress , displaying a tree of categories with product thumbnail display.
