结合js做的,具体的话相应要做修改,比如目录制

<script language="javascript">
with (document) {
        write("<STYLE TYPE='text/css'>");
        write(".child ")
        write("</STYLE>");
    }
function initIt(){
        divColl = document.all.tags("DIV");
        for (i=0; i<divColl.length; i++) {
            whichEl = divColl(i);
            if (whichEl.className == "child") whichEl.style.display = "none";
        }

}
function expandIt(el) {

        whichEl = eval(el + "Child");
        if (whichEl.style.display == "none") {
            whichEl.style.display = "block";
        }
        else {
            whichEl.style.display = "none";
        }
    }
onload = initIt;
</script>
<LINK href=../main.css rel=stylesheet type=text/css>
<?
