K2 Version 2.0.0 - Free Joomla Extensions
The K2 CCK (Content Construction Kit), made by Joomlaworks Greek (hhtp://www.joomlaworks.gr/) is a really powerful component for Joomla! 1.5.x.K2 provides an out-of-the box integrated solution featuring rich content forms for items (articles with additional fields for images and image galleries, videos, attachments and more), nested-level categories, tags, comments, a system to extend the item forms with additional fields, a powerful plugin API to extend item, category and user forms, ACL, frontend editing, sub-templates and 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 and more, all this bundled under one package! K2 is extensible with additional fields to its base content form. That means you can add as many content fields as you want and create category-specific content items, e.g. article, blog post, product page, directory listing.
