In Online Stores and Online Free Registration Sites, you may wish to affect the order in which your Products are displayed. The order in which your Products are displayed can be changed via a drag-and-drop interface within the Site configuration.
To change the order of Products in a Site, navigate to Registration > Configuration, and then click on the Sites tab. Select the Site you want to edit, and then use the drag-and-drop interface to re-order the Products, and then click Save.
