Javascript 下拉菜单，无法使SlideDown（）工作

我讨厌在这里张贴问题，因为我喜欢为自己找出一个解决方案，但我就是不能想出这个

我有一个导航菜单，是由wordpress吐出的，有3个深度。我正在尝试做一个大的下拉列表，我有它的运作只是css的罚款，但现在我正在寻找动画，只是有问题

下面是一个JSFIDLE：

代码如下：

    <div id="mid-nav">
  <ul id="midnav">
    <ul id="topmenu-{topmenu slug}[-{increment}]" class="topmenu">
      <li id="nav-menu-item-62" class="main-menu-item  menu-item-depth-0 menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-5 current_page_item"><a href="http://www.renewmywindows.com/" class="menu-link main-menu-link">Home</a></li>

还有我的借口jQuery的巨大失败：

    <script type="text/javascript">
$(document).ready(function () {
    //  $("#nav-menu-item-68").hover(function(){
    //      console.log($(this));

    //      alert("The slideDown() method is finished!");   });
    //      console.log($(this).children('ul'));
    //  },function(){
    //    $(this).find('ul').slideUp( "fast" );
    //        
    //    });
    //cache nav
    var nav = $("#mid-nav");

    //add indicator and hovers to submenu parents
    nav.find("li").each(function () {
        if ($(this).find("ul").length > 0) {
            $("<span>").text("^").appendTo($(this).children(":first"));

            //show subnav on hover
            $("#nav-menu-item-68").mouseenter(function () {

                $("testtt").stop(true, true).slideUp();
            });
        }
    });

});
</script>

这是我第一次尝试，但没有任何效果。我使用控制台日志记录来确保在其他情况下，我选择了正确的类/id

然后我做的下一件事与上面类似，但它只会滑动文本，而不会滑动整个内容

我已经想了很久了！啊

谢谢

我不知道问题出在哪里，它看起来很生动……是的，当我悬停时，新链接会向下滑动。哦，没关系，我单击了一个链接，它就转到了实际的站点。我想不，不是在小提琴上，对不起。我会再检查一遍。整理好，在fiddle中启用jQuery，修复了脚本中的一个语法错误：仍然不工作，但当我悬停时它会疯狂地滑动，也许你可以从这里开始工作。谢谢，我相信这都是CSS问题！怎么了？
