Articles: New or Edit Category
From Joomla! Documentation
Categories are are used to organize Articles, Contacts and other components for ease of management and display. They can be organised into tree-like structures like file systems. For example, category Pets may be a parent to category Dogs, category Cats and Category Goldfish. Categories can be nested to any level. All Articles must be assigned either to a parent Category or a child Category or to the special Category called 'Uncategorized'.
The edit form is used to create a new Category or to alter the properties of an existing Category.
How to Access
To add a new category, starting from the Administrator menu:
- Select Home Dashboard → Site panel → Categories + button. Or...
- Select Content → Categories + button. Or...
- Select Content → Categories. Then...
- Select the New button in the Toolbar to create a new Category. Or...
To edit an existing Category:
- Select Content → Categories. Then...
- Select a Category title From the list of categories.
- Title. The Title for this item. This may or may not display on the page, depending on the parameter values you choose.
- Alias. The internal name of the item, also used in the URL when Site Global Configuration SEO Setting is activated. Normally, you can leave this blank and Joomla! will fill in a default value. The default value is the Title or Name in lower case and with dashes instead of spaces. You may enter the Alias manually. The Alias should consist of lowercase letters and hyphens (-). No blank spaces or underscores are allowed. Non-Latin characters can be allowed in the alias if you set the Unicode Aliases option to Yes in the Site Global Configuration SEO settings. If this option is set to No and the title includes non-Latin characters, the Alias will default to the current date and time (for example "2012-12-31-17-54-38").
- Description. The description for the item. Category, Subcategory and Web Link descriptions may be shown on web pages, depending on the parameter settings. These descriptions are entered using the same editor that is used for Articles.
- Toggle Editor. If you are using the TinyMCE editor, a Toggle Editor button will show just below the edit window. This button allows you to toggle between the TinyMCE editor and No Editor.

- ID. The unique ID number automatically assigned to this item by Joomla!. This number cannot be changed.
- Meta Description. An optional paragraph to be used as the description of the page in the HTML output. This will generally display in the results of search engines. If entered, this creates an HTML meta element with a name attribute of "description" and a content attribute equal to the entered text.
- Meta Keywords. Optional entry for keywords. Must be entered separated by commas (for example, "cats, dogs, pets") and may be entered in upper or lower case. (For example, "CATS" will match "cats" or "Cats"). Keywords can be used in several ways:
- To help Search Engines and other systems classify the content of the Article.
- In combination with Banner tags, to display specific Banners based on the Article content. For example, say you have one Banner with an ad for dog products and another Banner for cat products. You can have your dog Banner display when a User is viewing a dog-related Article and your cat Banner display for a cat-related Article. To do this, you would:
- For articles only, in combination with the Related Articles module, to display Articles that share at least one keyword in common. For example, if the current Article displayed has the keywords "cats, dogs, monkeys", any other Articles with at least one of these keywords will show in the Related Articles module.
- Author. Optional entry for an Author name within the metadata. If entered, this creates an HTML meta element with the name attribute of "author" and the content attribute as entered here.
- Robots. The instructions for web "robots" that browse to this page.
- Use Global: Use the value set in the Component→Options for this component.
- Index, Follow: Index this page and follow the links on this page.
- No index, Follow: Do not index this page, but still follow the links on the page. For example, you might do this for a site map page where you want the links to be indexed but you don't want this page to show in search engines.
- Index, No follow: Index this page, but do not follow any links on the page. For example, you might want to do this for an events calendar, where you want the page to show in search engines but you do not want to index each event.
- No index, no follow: Do not index this page or follow any links on the page.
- Select a Category: Select or Create a Category to associate.
