jQuery的切換下拉菜單

Question

我怎麼能寫的jQuery的一部分，這樣，當試驗被點擊，它會顯示在下拉菜單中選擇：

更新：

jQuery(document).ready(function() { 

    $("a[href='http://sheep.local/cms/trials']").click(function(e){ 
     e.preventDefault(); // In case you don't want the link to open... 
     $(this).next('ul').slideToggle(); 
    }); 
});​ 

HTML：

 <div id="mainnavwrap"> 
      <div id="mainnav" class="clearfix">

你可以使用這樣的事情（只適用於審判）

$("a[href='http://sheep.local/cms/trials']").click(function(e){ 
    e.preventDefault(); // In case you don't want the link to open... 
    $(this).nextAll('ul').slideToggle(); 
});
