In the default theme of the store front, parent categories are listed in the top menu of the home page, and on the left side of product pages. This navigational feature is used to guide customers to similar products within the same category. Exposing customers to different products within a category lets the customer compare the similarities and differences between products to make the most informed purchase. When adding products to the store, you will be asked for a product category to sort them in. It is a good idea to establish these categories before adding products, to save yourself the trouble of adding the category name to the products later.
To access the Category page in the administration, hover over the Catalog button and click on Category in the drop-down. You will be a directed to a page that displays the category names of the store products (as seen below).
The categories above were included with the default products provided by the install. You may delete them to make room for the store's product categories. To delete, check the box next to the row that the category is listed on. When the products selected for deletion are checked, "Delete" can be clicked on in the upper right corner. This should remove the product categories completely.
The Sort Order indicates the order that the categories are displayed in the top menu and category box on the product page. Desktop (sort order-1) will be sorted above Laptops & Notebooks (sort order-2) because it has a higher priority.
Clicking "Edit" under "Action" will direct the administrator to a form to change the category information. Clicking "Insert" will allow the shop owner to insert more products to the site.
Before you learn how to add products, you will need to understand how to create product categories. Product category is an essential organizational feature in OpenCart. OpenCart organizes the structure of an online store around these product categories. Every product category gets their own space in the store to display all the available products for that category.
Organizing products into categories is useful for navigating a store's inventory in both the store front and administration side. In the administration, creating categories for products will help the shop owner keep track of specific products within a category. In the store front, customers will be able to browse their favorite products by category. Category pages can be accessed in the top menu and from the category box in the product page.
Go to Catalog > Category in the administration. If this is your first time in the category section you will see a list of categories created for the default products. You should feel free to delete them to make room for your store's products. To create a new category for products you can click "Insert" in the upper right corner. You will be directed to the category's information page. Category information can be filled out under three tabs: "General", "Data", "Design".
