Hvordan laves Drop down menu?

et meget hurtig eksempel:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
    <title>Untitled</title>
    <style>
    .subMenu
    {
        display:none;
    }
    </style>
    <script language="JavaScript" type="text/javascript">
    <!--
    function openMenu( p_strMenu )
    {
        var objSubMenu = document.getElementById( "subMenu" + p_strMenu );
        if( objSubMenu )
        {
            if( objSubMenu.style.display == 'none' || objSubMenu.style.display == '' )
            {
                objSubMenu.style.display = 'inline';
            }
            else
            {
                objSubMenu.style.display = 'none';
            }
        }
    }
    //-->
    </script>
</head>

<body>
<a href="java script:void(0);" onclick="openMenu('1');">1</a><br>
<div id="subMenu1" class="subMenu"><a href="java script:void(0);">Sub 1</a><br>
<a href="java script:void(0);">Sub 2</a><br></div>
<a href="java script:void(0);" onclick="openMenu('2');">2</a><br>
<div id="subMenu2" class="subMenu"><a href="java script:void(0);">Sub 1</a><br>
<a href="java script:void(0);">Sub 2</a><br></div>
<a href="java script:void(0);" onclick="openMenu('3');">3</a><br>
<div id="subMenu3" class="subMenu"><a href="java script:void(0);">Sub 1</a><br>
<a href="java script:void(0);">Sub 2</a><br></div>
<a href="java script:void(0);" onclick="openMenu('4');">4</a><br>
<div id="subMenu4" class="subMenu"><a href="java script:void(0);">Sub 1</a><br>
<a href="java script:void(0);">Sub 2</a><br></div>

</body>
</html>
