As there are few good accordion menus out there I decided to give this one a try because of the great reviews. Here's another positive review of this extension, this is a very smooth menu system. The style set up with the gradient is really great! Very classy looking menu with a lot of great functions. The only difficulty I had involved the CSS, there isn't a typical CSS file to modify (that I could find). The only one that exist is located in the cache and is dynamically generated by the PHP code. So, you have to modify the CSS that's embedded into the theme.css.php file of whatever theme you are using. This is not a huge issue, but can be confusing if you are looking for a CSS file to modify. I was able to create rollovers and different effects by modifying the PHP and CSS. Very pleased with the results and this extension! Great job!
