The way I'd go about it would be to add content ~~indie~~ inside each menu item. You decide whether or not to show this content based on the class of it's parent. Then, whenever you click the parent element, you simply toggle a class name.

Here's a rough sample. The styles are pretty nasty, but it demonstrates the purpose.
Also, you shouldn't really use inline javascript on the html elements like I did. You should give them a class and then addEventListener for 'click' on any <li> element that has this className. I'll leave that as an exerise for you.

HTML

<!DOCTYPE html>
<html>
<head>
<script>
function byId(e){return document.getElementById(e);}
function newEl(tag){return document.createElement(tag);}
function newTxt(txt){return document.createTextNode(txt);}

window.addEventListener('load', mInit, false);

function mInit()
{
}

function toggleClass(element, newStr)
{
    index=element.className.indexOf(newStr);
    if ( index == -1)
        element.className += ' '+newStr;
    else
    {
        if (index != 0)
            newStr = ' '+newStr;
        element.className = element.className.replace(newStr, '');
    }
}

</script>
<style>
li ul
{
    display: none;
}
li.open ul
{
    display: block;
}
</style>
</head>
<body>
    <ul>
        <li onclick='toggleClass(this, "open");'>Option 1
            <ul>
                <li>opt 1a</li>
                <li>opt 1b</li>
            </ul>
        </li>
        <li onclick='toggleClass(this, "open");'>Option 2</li>
        <li onclick='toggleClass(this, "open");'>Option 3
            <ul>
                <li>opt 1a</li>
                <li>opt 1b</li>
            </ul>
        </li>
    </ul>
</body>
</html>
