The accordion menu is smoother and works better.
If you want to show your archives the Wordpress style on your Joomla! 1.5 / 1.6 / 1.7 / 2.5 site. This is the Module to start using.
Wanna see a demo ?
There is a Major Joomla! 1.5 bug in where you cannot use SEF when opening a Archive URL. The URL to the Archive list is wrong. Joomla! did not solve this problem yet. (bug tracker : http://snurl.eu/pxbwp)Joomla! 1.5 / 1.6 / 1.7 / 2.5 ready!
If you want the module see working go to the archives menu item (some how joomla does the right SEF thing there))
Please pick the right version for your Joomla! version !
You can download sourcecode here on github.
