Easy Accordion is a highly flexible jQuery plugin for creating horizontal accordions quickly.

It generates the accordion from definition lists (dts, so it is SEO friendly) and has support for multiple instances to be ran on the same web page.

The plugin can slide any content like images, lists, Flash, etc. and its look can be totally customized via CSS.

There are multiple options offered like setting the slide to be displayed on initial load, auto-display to be on/off and including the slide number or not.

Official Words:

A couple of months ago I found myself looking for a jQuery plugin to create a horizontal accordion. I needed a simple and clean solution for one of my projects and, at a first glance, Slidedeck seemed to be what I was looking for. Unfortunately, this turned out to be not that flexible as I wished it to be.
Hence, I decided to create my own horizontal accordion plugin.
