“A while back I did a project that required a horizontal accordion. I eventually found a plugin, but really wasn’t happy with the results. The setup was pretty messy and to get the plugin working like I wanted, it took more time than it was worth.
I also did not want text in the handle or tab area. I wanted it to be more like an image slider. So I decided to do some coding after the project was complete and ended up with my first jQuery plugin.”
Example of use:
$(document).ready(function() { $("#featured").zAccordion({ easing: "easeOutBounce", timeout: 5500, slideWidth: 600, width: 960, height: 310 }); });
