Article In Joomla! an Article is a piece of content consisting of text (HTML), possibly with links to other resources (for example, images). Articles are the basic units of information in the content system and the bottom level in the content hierarchy. Since Joomla! 2.5 , each Article is in exactly one Category. A Category can be in another Category making it a sub Category. It is also possible to have Uncategorised Articles. These articles exist without being associated with any Category. 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 alway 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.

Category In Joomla! a Category is a collection of Articles. In Joomla! a website might have Categories called "Animals" and "Plants". Within the "Animals" Category, the website might have Sub Categories such as "Birds" and "Mammals". Within the "Birds" Category, the website might have Articles such as "Parrots" and "Sparrows". The example above could be expanded even more with specific articles on different species of Parrots and Sparrows. Start with using an "Animal" Top Category. Placing the Sub Categories "Birds" and "Mammals" are under the Animal category, and then a "Parrots" and "Sparrows" Sub Category under the "Birds" Sub Category as shown. Animals Birds Parrots Sparrows Mammals Now you can create multiple articles in the Parrot and Sparrow Categories. Categories are maintained using the Category Manager which can be reached in the Administrator (Back-end) by clicking on the Content menu, then the Category Manager menu item.
