Horizontal Accordion Script is a jQuery Plugin which turns an ordinary UL list into a horizontal accordion. You can easily change the look and feel via CSS and customize its functionality with the help of various options. Horizontal Accordion is cross browser script and has been tested to work on IE6+, Firefox and Opera.
The HTML markup of the Accordion (UL list) can either be defined inline on the page, or inside an external file instead and fetched via Ajax. Plus you can specify which LI should be expanded by default, whether to persist the last expanded LI (within a browser session), and also, expand a particular LI by passing in different parameters into the URL string. All this makes for a versatile, smooth horizontal accordion.
