The Joomla! content management system lets you create webpages of various types using extensions. There are 5 basic types of extensions: components, modules, templates, languages, and plugins. Your website includes the extensions you need to create a basic website in English, but thousands of additional extensions of all types are available. The Joomla! Extensions Directory is the largest directory of Joomla! extensions.
Components are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed.In the Joomla! administrator there are additional extensions suce as Menus, Redirection, and the extension managers.
Modules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 17 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.
Navigation modules help your visitors move through your site and find what they need.
Menus provide your site with structure and help your visitors navigate your site. Although they are all based on the same menu module, the variety of ways menus are used in the sample data show how flexible this module is.
A menu can range from extremely simple (for example the top menu or the menu for the Australian Parks sample site) to extremely complex (for example the About Joomla! menu with its many levels). They can also be used for other types of presentation such as the site map linked from the "This Site" menu.
Breadcrumbs provide users with information about where they are in a site.
Templates give your site its look and feel. They determine layout, colors, type faces, graphics and other aspects of design that make your site unique. Your installation of Joomla comes prepackaged with four templates. Help
Plugins are small task oriented extensions that enhance the Joomla! framework. Some are associated with particular extensions and others, such as editors, are used across all of Joomla!. Most beginning users do not need to change any of the plugins that install with Joomla!. Help
Here is where I will blog all about the parks of Australia.
You can make a blog on your website by creating a category to write you blog posts in (this one is called Park Blog). Each blog post will be an article in that category. If you make a category blog menu link with 1 column it will look like this page, if you display the category description (this part) displayed.
We search the whole countryside for the best fruit growers.
You can let each supplier have a page that he or she can edit. To see this in action you will need to create a users who is in the suppliers group. Create one page in the growers category for that user and make that supplier the author of the page. That user will be able to edit his or her page.
This illustrates the use of the Edit Own permission.
