Jquery Vertical Slider Help, Scrolling More Items
<p>I'm using this code to have a vertical scroller like a news one but showing different products, I'm having trouble getting it to scroll past more than 9 items without it restarting the loop, changing navItemsDisplay to anymore than that and my vertical scroller "bumps down" inside the div but not actually scrolling past 9, I've editted the code below, and this one is jquery, it also uses jquery.easing.js as well. (thanks for the info about mootools)</p>
