If you want me to modify the CSS for you simply <a href="http://www.zackdesign.biz" title="Zack Design" rel="nofollow ugc">contact me</a> and I will do it easily and quickly for you for a moderate sum.
It uses <a href="http://www.cssplay.co.uk/menus/final_drop.html" title="Stu Nicholl" rel="nofollow ugc">Stu Nicholl’s final drop-down code</a> which is a complete CSS solution – no Javascript required!!
You can look on <a href="http://www.cssplay.co.uk/menus/" title="Stu Nicholl's Menus" rel="nofollow ugc">Stu’s site for other drop-down code</a> as I got the flyout left and right code from there. Don’t forget to donate if you’re using his styles.
Most of his CSS should work just fine with the menu. I’ve made it so that the plugin automatically finds menu.css in the plugin’s folder and loads it in your WordPress site so you can instantly see how it will look. If you want to create your own CSS simply create menu.css in your theme’s root directory and the plugin will load that automatically for you.
Please note that if you’re upgrading you will need to change your theme files to suit the new approach. See Installation for further information.
