K2 provides an out-of-the box integrated solution featuring rich content forms for items (think of Joomla articles with additional fields for article images, videos, image galleries and attachments), nested-level categories, tags, comments, a system to extend the item base form with additional fields (similar to CCK for those acquainted with Drupal), a powerful plugin API to extend item, category and user forms, ACL, frontend editing, sub-templates & a lot more!

Using K2, you can transform your Joomla website to a news/magazine site with author blogs, product catalogs, work portfolio, knowledge base, download/document manager, directory listing, event listing & more, all this bundled under one package!

Give K2 a try & you'll instantly love it! It's easy to use and fun to develop websites with! If you need any help or want to contribute to the project, join us at the K2 community.


Since K2 is extensible with additional fields to its base item form, you can easily create category-specific content types, e.g. article, blog post, product page, directory listing.

K2 offers as standard:
- nested-level categories
- commenting, integrated with Google's reCaptcha & Akismet
- tags
- distinct item image (useful for articles/catalogs)
- image galleries
- videos
- attachments
- user pages (author blogs/user profiles)
- smart ACL for frontend editing
- unique plugin system to extend item, category & user forms
- AJAX based frontend editing & comments moderation
- Rest-like JSON/JSONP content output
- Native advanced SEF options
- Flexible sub-templates (for every content output)

K2 fully supports the Joomla API, which means any Joomla plugins will function properly within the K2 component & modules, either in the frontend or backend.


Pixeden, Groupama, Harvard, High Court of Australia, Amnesty International, Arturia, Vivaldi Web Brower & the Joomla Magazine are just some of the thousands of top Joomla sites around the world, fully powered by K2.


To utilize the built-in video & gallery features you need to install AllVideos (free) & Simple Image Gallery Pro, both provided by JoomlaWorks.

K2 is developed by JoomlaWorks & licensed under the GNU/GPL license.


Try K2! Install it, hit the "import" button to bring your Joomla articles inside K2, start playing with the component to see the flexibility it provides first-hand. Moreover? You no longer need a dozen of components & even more modules to do things like run a news site or a blog. Drupal & Wordpress have certainly met their match now!

Just What I Need!

Posted on 21 April 2009
FINALLY, exactly what I'm looking for! I stumbled upon this after weeks of searching for what this component does.

I love the simple but elegant look of the items and categories when displayed. It's great how the comments and tags come all in one because my site was starting to look patchy with all the different things I was using. Thanks so much!

Very good, but

This is an excellent extension, very versatile, comprehensive and I would like to see it replace the main article/section/category in Joomla. However, there are a few things I would suggest.

Rather than creating a whole new way to submit articles, and even re-creating the article section why not just utilise the current article section and category section and integrate the additional functionality into the core. Also, I have a great menu system installed on a test site that this extension completely breaks. Again, with correct core integration this would be an amazing extension.

Great Component!

I've been using this for 1 week now. I've been really satisfied with what it can do. Never been so easy to add and edit articles, but don't know how and why it stopped functioning properly.

1. Getting buggy articles' intro (image captions showing even if disabled.

2. When disabling photo gallery and related video, still showing in front-end.

Would be better if you could add a plugin or module to be able to display intro articles on joomla frontpage itself.

Waiting for a stable version .
Owner's reply: Regarding the display of elements in the frontend, make sure you've set both the global parameters in K2 and the params of each menu item you create. It's essential to properly display things. ;)

The current module is pretty powerful to do what you ask already.
Wow, a CMS within a CMS. That's all there is to it. This must be the best content related extension for Joomla 1.5. It is very easy to use, I installed it with the sample data and felt right at home with this component. Setting up a Blog on Joomla has never been easier. This component leaves o wishes open! The only thing that I can not believe is that it is GNU/GPL. Keep up the good work JoomlaWorks. This onenis staying on my site!

Great Job !

Thats what many were surely waiting for for a long time ! This component might be able to replace the category view of Joomla as well as the many "news-list" modules and components swirling around !

Install this component first and then think if you need any other extension !

One small flaw that I couldnt figure out - after posting a comment the message "Page reloading..." appears but nothing happens. Hope that could be solved as well to make this component the no.1 in content news display. Thanks for your work !
Owner's reply: Comments use Mootools, which is the default javascript framework for Joomla! Check if it's disabled for some reason. ;)
