//** Smooth Navigational Menu- By Dynamic Drive DHTML code library: http://www.dynamicdrive.com

//** Script Download/ instructions page: http://www.dynamicdrive.com/dynamicindex1/ddlevelsmenu/

//** Menu created: Nov 12, 2008



//** Dec 12th, 08" (v1.01): Fixed Shadow issue when multiple LIs within the same UL (level) contain sub menus: http://www.dynamicdrive.com/forums/showthread.php?t=39177&highlight=smooth



//** Feb 11th, 09" (v1.02): The currently active main menu item (LI A) now gets a CSS class of ".selected", including sub menu items.



//** May 1st, 09" (v1.3):

//** 1) Now supports vertical (side bar) menu mode- set "orientation" to 'v'

//** 2) In IE6, shadows are now always disabled
