为什么这个树型菜单初始状态是打开状态，而不是收缩状态（有相关代码）

上面的代码是根据以下的代码写的，但是下面的代码初始状态确实未打开的<html>
<head>

  1.   

    加上class='child'即可<div  id="KB1Child"  class='child'> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~&nbsp;<a class=B16  href="fgfsg.htm" target="_target"><img src="image/blank.gif" border="0" />国内动态</a><br />
    &nbsp;<a class=B16  href="fgfsg.htm" target="_target"><img src="image/blank.gif" border="0" />国际时讯</a><br />
    &nbsp;<a class=B16  href="fgfsg.htm" target="_target"><img src="image/blank.gif" border="0" />台湾动态</a><br />
    </div>
    <div  id="KB2Parent">
    <a class=B16 onclick="expandIt('KB2'); return false" href="#">
    <img src="image/plus.gif"  border="0" />宏观经济</a><br />
    </div>
    <div  id="KB2Child" class='child'>
      

  2.   

    <div  id="KB1Child"  class='child'>
    <div  id="KB2Child" class='child'>
