Contained Sticky Scroll jQuery Plugin
Contained Sticky Scroll allows you to create an element that will “stick” to the top of the window as the user scrolls, but which will not move outside of its parent element.
The download package contains both full and minified versions of the .js file, along with a demo page which explains the various options that can be used to configure each initialization of the plugin’s functionality. It has been tested the plugin in recent versions of Firefox, Chrome, Safari and even Internet Explorer 8.
