//** 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

//** July 27th, 09" (v1.31): Fixed bug so shadows can be disabled if desired.
