Haiku has new functionality available for your webpages. Previously, the webpage template provided you with a left hand navigation and a single column for content. You now have the option to change the display to a three column layout, allowing you to use portlets on both the right and left sides of the text.
When using the three column layout, you will be able to use both the primary and secondary portlets, allowing you to present your content in new and interesting ways.
You can see the release notes here.
You can see the documentation for how to use this feature here.
We hope you enjoy mixing things up with your webpages.
The Haiku Team.
