With Joomla 1.6’s nested category method of site organization, there’s no limit to the number of categories that you can implement on a site. A nested category is just a fancy name for category within a category. For example, you could divide an Ice Cream category into a number of nested categories: Bars, Cartons, and Cones or a Sandwiches section into three nested categories: Subs, Wraps, and Triple Deckers.

To create a new nested category, follow these steps:

  1. Click the Category Manager icon in the control panel, or choose Content→Category Manager in any back-end page.

    Category Manager opens.

  2. Click the New button.

    The Add New Category page opens.

  3. Enter a title for the category in the Title text box.

    For this exercise, type Cartons.

  4. From the Parent drop-down menu, choose the category you want this nested category to go into.

    For this exercise, choose Ice Cream.

  5. Choose a status from the State drop-down menu.

    For this exercise, choose Published.

  6. Choose an option from the Access drop-down menu to specify who can access the articles in the section.

    For this exercise, choose Public.

  7. In the Description window, enter a description of your new section.

    For this exercise, type This is SuperDuperMegaCo’s Ice Cream Cartons category.

  8. Click the Save & Close button.

    The Add New Category page closes, and you return to Category Manager, where you see the new category.
