Use WordPress' nav menu system to create left/right widget flyouts, with support for Superfish
(Un)fortunately the WordPress nav menu system doesn't use the browser hacks Stu Nicholl used. There are many other CSS navigation menus out there these days, do a quick Google search, pop it into your own menu.css file, and target the correct class. It's easy to drop over the top!
That's what I'm here for. I do WordPress sites for many people in a professional capacity and can do the same for you. Check out http://www.zackdesign.biz
You need PHP 5 to run this
I left dynamic menu width code in until a replacement CSS menu can be found... it should not break existing dynamic CSS, but you can no longer change the options in the WP Settings.
Contact me to suggest a good alternative, and if you need to change any of the options found in the
css_dropdownmenu_css function use functions.php and this as a guide: http://codex.wordpress.org/Function_Reference/update_option
