我正在使用水平滑动手风琴，并且我在悬停时让每个元素变为活动（展开），但是在休眠状态下，初始活动元素应该展开，而不是所有LI折叠。
请参阅示例 http://jsfiddle.net/WT8Tg/
<ul class="accordion" id="accordion">
<li class="bg1">
<div class="heading">Guler</div>
<div class="bgDescription"></div>

答案 0 :(得分：0)
您只需添加一些规则即可适应该行为。
我在悬停时添加了这个：
$('li').stop().animate({'width':'115px'},1000);
我在悬停结束时添加了这个：
$('.bg4').stop().animate({'width':'480px'},500);
我强烈建议使用类来分配宽度，而不是在Javascript中对其进行硬编码。然后，您可以为删除/添加类添加动画。
