//** Chrome Drop Down Menu- Author: Dynamic Drive (http://www.dynamicdrive.com)

//** Updated: July 14th 06' to v2.0
//1) Ability to "left", "center", or "right" align the menu items easily, just by modifying the CSS property "text-align".
//2) Added an optional "swipe down" transitional effect for revealing the drop down menus.
//3) Support for multiple Chrome menus on the same page.

//** Updated: Nov 14th 06' to v2.01- added iframe shim technique

//** Updated: July 23rd, 08 to v2.4
//1) Main menu items now remain "selected" (CSS class "selected" applied) when user moves mouse into corresponding drop down menu. 
//2) Adds ability to specify arbitrary HTML that gets added to the end of each menu item that carries a drop down menu (ie: a down arrow image).
//3) All event handlers added to the menu are now unobstrusive, allowing you to define your own "onmouseover" or "onclick" events on the menu items.
//4) Fixed elusive JS error in FF that sometimes occurs when mouse quickly moves between main menu items and drop down menus

//** Updated: Oct 29th, 08 to v2.5 (only .js file modified from v2.4)
//1) Added ability to customize reveal animation speed (# of steps)
//2) Menu now works in IE8 beta2 (a valid doctype at the top of the page is required)

var cssdropdown = {
    disappeardelay: 250, //set delay in miliseconds before menu disappears onmouseout
    dropdownindicator: '', //specify full HTML to add to end of each menu item with a drop down menu
    enablereveal: [false, 5], //enable swipe effect? [true/false, steps (Number of animation steps. Integer between 1-20. Smaller=faster)]
    enableiframeshim: 1, //enable "iframe shim" in IE5.5 to IE7? (1=yes, 0=no)
