Collapse Outside the frame

Hi, I have a script which collapses the menu, inside its frame.

PHP Code:

<script language="JavaScript">

function collapseMenu(sectionID) {

var obj = document.getElementById(sectionID);

if (obj.className == "Collapse") {

obj.className="DeCollapse";

}

else {

obj.className="Collapse";

}

}

</script>

Is it possible to have it expand and collapse outside the frame?

For example similar to the onMouseover drop-down menu. (Example: http://www.resellerspanel.com/)

I'm no good with flash so I'd like to keep to javascript and PHP.
