How to Access
- Select Content → Categories from the drop-down menu on the back-end of your Joomla! installation.
- Click the Categories link while viewing Articles, Featured Articles, Fields or Field Groups in the left, upper sidebar.
The Category Manager is where you can view existing Categories in a table layout. Click the Category names to edit the existing categories or click the 'New' Toolbar button to create new ones. All articles in Joomla! are organized into Categories and Subcategories. Subcategories are the second level of organization underneath Categories. The special Category 'Uncategorized' is category created with the Joomla! installation and built into Joomla!.
In the table containing Categories, these are the different columns as shown below.
- Ordering: Up-Down Arrows User specified ordering, default is order of item creation. When active, drag and drop ordering by 'click and hold' on the bars icon then 'release' in desired position.
- Checkbox: Check this box to select one or more items. To select all items, check the box in the column heading. After one or more boxes are checked, click a toolbar button to take an action on the selected item or items. Many toolbar actions, such as Publish and Unpublish, can work with multiple items. Others, such as Edit, only work on one item at a time. If multiple items are checked and you press Edit, the first item will be opened for editing.
- Status. Status of Category, Published or Unpublished are shown with icons as follows:
- Title. The name of the item. For a Menu Item, the Title will display in the Menu. For an Article or Category, the Title may optionally be displayed on the web page. This entry is required. You can open the item for editing by clicking on the Title.
- Published: Whether the item has been published or not. You can change the Published state by clicking on the icon in this column.

- ID. This is a unique identification number for this item assigned automatically by Joomla!. It is used to identify the item internally, and you cannot change this number. When creating a new item, this field displays 0 until you save the new entry, at which point a new ID is assigned to it.
Above the column headers on the right, there are 2 drop down input fields, Sort Table by: (preset to Ordering ascending) and a number (preset to 20) to display.
These column sorting input fields shows the current method of sorting applied to the table. Use the drop down field choices and click the column heading name. Alternatively, click on the column heading to sort the list by that column's value. This will also change the value in the drop field to correspond with the column header name. The list will then be sorted in order by that column and a sort icon(up or down arrow) will show next to the column name. Click a second time to reverse the sort, which will change the corresponding drop field.
- Order. Order items will be displayed in.
- Ascending Shows ordering of selected column, ascending or descending.
- # (default is 20). Shows the number of items to display on one page, default is 20 items. If there are more items than this number, you can use the page navigation buttons located at the bottom of the table. (Start, Prev, Next, End, and page numbers) to navigate between pages.
The Batch Process allows a change in settings for a group of selected categories marked with a check-mark in the corresponding check-mark boxes. To use: select one or more categories form the table of categories being viewed and click on the 'Batch' Toolbar button. This will open a pop up window as shown below.
You can change one value or all values at one time.
Note: if you copy items to a new category, changes you have selected from language and access level will be applied to the copies, not the original.
How to Batch Process a group of categories:
- Select one or more categories on the list by selecting the desired checkbox(es).

- To move the items to a different category, select the desired category from the category list box and check the Move option. In this case, the original items will be moved to a new category and, if selected, be assigned the new language and access level.
