/*****************************************************
* ypSlideOutMenu
* 3/04/2001
*
* a nice little script to create exclusive, slide-out
* menus for ns4, ns6, mozilla, opera, ie4, ie5 on 
* mac and win32. I've got no linux or unix to test on but 
* it should(?) work... 
*
* Revised:
* - 08/29/2002 : added .hideAll()
*
* --youngpup--
*
* Revised by Lolo Irie to use with e107 CMS:
* ypSlideOutMenu.showMenu altered to display as absolute OR relative position (menu area)
* ypSlideOutMenu.showMenu altered to define submenus position (absolute or relative to mouse position)
*
* This javascript can ONLY be used if authorized by the webmaster of youngpup.net or by Lolo Irie of touchatou.org (free for e107users)
