![]() Note: Your Main Menu is a Module! When you create a new Menu in the Menu Manager you are actually copying the Main Menu Module ( mod_mainmenu) code and giving it the name of your new Menu. You can also set which Menu Items (and thus pages) a Module will display on, you can select all Menu Items or you can pick and choose by holding down the control key and selecting multiple locations one by one in the Modules screen ![]() If you wish it to display in two different locations you must copy the Module and assign the copy to display at the new location. Displaying ModulesĮach Module is assigned to a Module position on your site. For example, "left" and "right" are common for a 3 column layout. Modules can be assigned to Module positions which are defined in your Template and in the back-end using the Module Manager and editing the Module Position settings. They work in conjunction with Components in some cases and in others are complete stand alone snippets of code used to display some data from the database such as Articles (Newsflash) Modules are usually used to output data but they can also be interactive form items to input data for example the Login Module or Polls. Modules are like little mini-applets that can be placed anywhere on your site. Similarly, Modules can be rendered regardless of which Component you have loaded. Footnotes also might appear regardless of which chapter you are reading. Obviously you can have a footnote on any page but not all pages will have them. To continue in our book analogy, a Module can be looked at as a footnote or header block, or perhaps an image/caption block that can be rendered on a particular page. Modules are used for small bits of the page that are generally less complex and able to be seen across different Components. ModulesĪ more lightweight and flexible Extension used for page rendering is a Module. Integration of 3rd party components with Joomla core components is the main development challenge for Joomla web designers. There are hundreds of commercial components that can be used to create amazingly complex websites. Many open-source Joomla components are of remarkable quality and very mature ( VirtueMart, for example). In addition, when designing a website with specific requirements, designers can use 3rd party components to enable the required functionalities. They make it possible to completely transform Joomla! and greatly expand its capabilities. Components do a lot of behind-the-scene work and usually contain data.Ĭomponents work hand in hand with Modules and Plugins to provide a rich variety of content display and functionality aside from the standard Article and content display. Many of Joomla!'s core features are provided by the use of default Components such as:Ī Component will manage data, set displays, provide functions, and in general can perform any operation that does not fall under the general functions of the core code. ![]() The core Article Component ( com_content), for example, is the mini-application that handles all core Article rendering just as the core registration Component ( com_user) is the mini-application that handles User registration. An analogy that might make the relationship easier to understand would be that Joomla! is a book and all the Components are chapters in the book. ComponentsĪ Component is the largest and most complex of the Extension types. You can read more about the specifics of these using the links in the Article Index - a Table of Contents (yet another useful feature of Joomla!) - at the top right or by clicking on the Next link below. Prepare to be amazed at the amount of exciting work produced by our active developer community!Ī useful guide to the Extension site can be found at: You can find more examples over at our ever growing Joomla! Extensions Directory. ![]() Here are just some examples of the hundreds of available Extensions: Īn Extension is used to add capabilities to Joomla! that do not exist in the base core code. This certificationn is one of the most reputable in the software development world - GNU License. All Joomla extensions - commercial or free-for-download - undergo a thorough certification process before they are released to users on the official website. There are over 7000 Joomla extensions! They provide an ability to create complex sites within days - and with high quality too. But for many people, the true power of Joomla! lies in the application framework that makes it possible for developers all around the world to create powerful add-ons that are called Extensions. Joomla Extensions Out of the box, Joomla! does a great job of managing the content needed to make your website sing.
