How to Create a Nested Category in Joomla Content Management
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:
Click the Category Manager icon in the control panel, or choose Content→Category Manager in any back-end page.
Category Manager opens.
Click the New button.
The Add New Category page opens.
Enter a title for the category in the Title text box.
For this exercise, type Cartons.
From the Parent drop-down menu, choose the category you want this nested category to go into.
For this exercise, choose Ice Cream.
Choose a status from the State drop-down menu.
For this exercise, choose Published.
Choose an option from the Access drop-down menu to specify who can access the articles in the section.
For this exercise, choose Public.
In the Description window, enter a description of your new section.
For this exercise, type This is SuperDuperMegaCo’s Ice Cream Cartons category.
Click the Save & Close button.
The Add New Category page closes, and you return to Category Manager, where you see the new category.
