我修改这个例子：http://www.queness.com/post/256/horizontal-scroll-menu-with-jquery-tutorialjQuery的动画问题
的问题是，当我尝试动画水平特定<div>菜单项。它不起作用。
//Animate the LI on mouse over, mouse out
$('.menu_item').click(function() {
//Make LI clickable
clickedItem = event.target.id;
//alert(clickedItem);
$("#m01").animate({left:"600px"},{duration: 3000,easing: 'easeOutQuad'});
但是如果我改变#m01说#menu这是所有菜单项的容器。动画效果良好，垂直滚动将继续完美发挥水平动画的作用。
我想要实现的基本最终效果是菜单将隐藏在屏幕之外，除了一些“选项卡”，并且当这些选项被选中时，将滑出显示菜单项。
的完整代码，请注意我改变了代码从教程从li项目divs，因为我原以为，也许我不能动画单独li项目：
