//** 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.



//** Feb 2nd, 10" (v1.4): Adds ability to specify delay before sub menus appear and disappear, respectively. See showhidedelay variable below







var ddsmoothmenu={







//Specify full URL to down and right arrow images (23 is padding-right added to top level LIs with drop downs):



arrowimages: {down:['downarrowclass', 'down.gif', 23], right:['rightarrowclass', 'right.gif']},



transition: {overtime:300, outtime:300}, //duration of slide in/ out animation, in milliseconds



shadow: {enable:true, offsetx:5, offsety:5}, //enable shadow?



showhidedelay: {showdelay: 100, hidedelay: 200}, //set delay in milliseconds before sub menus appear and disappear, respectively
