From Joomla! Documentation
Before Joomla! 2.5 and earlier versions, an Article was the third level in the hierarchy Sections → Categories → Articles. Now an Article is a bottom level and will always be the second level or greater in hierarchy.
- Category → Articles
- Category → sub Category → Articles
- Category → sub Category → sub Category → Articles
Articles are maintained using the Article Manager (see the Content Article Manager for or the Content Article Manager for ) which can be reached in the Administrator (Back-end) by clicking on the Content menu, then the Article Manager menu item.
