To add a new sub-category to your store catalog:

1. Log in to your Zen Cart store Admin
2. From the Catalog menu, select Categories/Products.
3. Click through to the category you wish to create a sub-category within.  In this example, I have selected Hardware by clicking either on the green Edit icon or on the category name.
4. Click on the New Category button. Note: A category cannot contain both products and sub-categories.  You will not see the New Category button if the category already contains products.  Likewise, for a category that contains sub-categories, the New Product button will not be available.
   
5. Enter a name for the category in the Category Name field.
6. Enter a description in the Category Description field.
7. Either select an image by using the Browse button or type an image name (that has already been FTP’d to your server) in the filename box.
8. If you would like your categories to appear in a specific order, enter a number in the Sort Order field.
9. Click the Save button to create the new sub-category.
