Publishing products with ShopConstruct is easy and intuitive.
At first please note that plugin does not require a special theme to install. It works with any theme and provides different shortcodes and automatically generated pages do display your products.
So you can publish either Single Product, products grid or Catalogs.
For Single products use single product shortcodes. To get the product shortcode, go to Products tab and find the shortcode displayed on the list.
To publish Catalogs, group them under the same category first. After that, use category shortcode to publish the whole group of the products. Get the catalog shortcode from the Categories tab of the plugin. See how to set up categories.
