There are two possible ways to add a category in X-Cart - manual and via import facilities. This article is about manual category creation.
To add a new category in an X-Cart store catalog:
In the "Categories" section of your store Admin area (Catalog -> Categories), click the "New category" button.
In the field that appears, enter the category name you require.
You can add as many new categories as you require at a time.
The category will be added to the list.
A category can have subcategories that are created similarly. Subcategories are, in fact, categories of a lower level. You can create subcategories on the Subcategories tab of the category details page with the "New Category" button.
To edit a category/subcategory, click on its name on the listing page and follow the procedures described in Editing Category Details.
