Here is a neat slide menu that I use. It follows the user no matter where he is on the page. So if he scrolls down, so does the side menu. If he pans to the right, so does the menu!
slidemenu.js (This is in a text file but name your file slidemenu.js or embed it into your HTML under the HTML code that uses this)
Here is the HTML portion of it:
slidemenu_html.txt (paste this code into your web page between the </head> and <body> tags! I know it sounds wierd but that is where it goes and may work within the header but I haven't tried, I am just following instructions. lol)
