/**** HTML USAGE ******

The menu will be aligned right under the MenuBarItem. The NUM in the Menu and MenuBarItem 
must be the same in order to be displayed correct.

<div id="MenuBarItemNUM">a title</div>

<div onselectstart="return false;" style="position:absolute; top:0;" id="divMenuNUM">
all the stuff in the menu
