Sorting the products by position:
- Open the Manage categories page (the link to this page is in the Catalog side box on the left of your administrator panel).
- Click on the amount of the products link in the row of the desired category. On the opened page you will be able to define position of your products for this selected category.
NOTE: The defined positions affect the sorting only if the Default sorting is selected in the Sort by section on the product list page in the storefront.
If you wish Default to be the default sorting, when a visitor opens a category page, select Default in the Product list default sorting select box in the Appearance section of the Settings page in the panel.
