// Cascading Popup Menus v5.2 - Single Frame Menu example script.
	
	
	// If you're upgrading from v5.1, you can paste your existing menu data in, and if you're
	// upgrading from v5.0 you need to add 'cursor' settings to your ItemStyles.
	//
	// And before going ANY further, you must have READ and AGREE TO the script license!
	// It can be found on my site, in the syntax helpfile, or in the demo script document.
	
	
	// 'horizontal Bar' style: menu items that use this ItemStyle are 40px wide, have 10px gaps
	// between them, no popout indicator (the ">" in some menus) or popout indicator position,
	// 0px padding of the text within items, #336699 background colour, a hover colour of #6699CC,
	// 'highText' is the stylesheet class used for the menu text both normally and when highlighted,
	// no border styles, 'null' means fully opaque items (set them to numbers between 0 and 100 to
	// enable semitranslucency), and the 'hand'/'default' cursors are used for linked/submenu items.

	// 'itemBorderBlank', 'itemBorder', null, null, 'hand', 'default');
	
	// The purplish 'button' style also has 1px spacing to show up the fancy border, and it has
	// different colours/text and less padding. They also have translucency set -- these items
	// are 80% opaque when dim and 95% when highlighted. It uses the 'crosshair' cursor for items.

	//    hBar: the ItemStyle used to give this menu colours and layout/formatting.
	//      '': this menu does not display within a frame (see the Frameset Example Script to do that).
	//   false: this menu shows submenus on mouseover. 'true' means show on click.
	//

	// to pop open a new window. I've also given each item a length in pixels, overriding the ItemStyle.

	// The last item here changes its text on mouseover (^ separates the two strings), links to my site,
	// and has a custom ItemStyle and length specified so it's longer than the rest.
	
	
	// HIDE OR SHOW DELAYS (in milliseconds) can be customised. Defaults are:
	//showDelay = 0;
	//hideDelay = 500;
	// Specify hideDelay as zero if you want to disable autohiding, and showDelay as a couple of
	// hundred if you don't want the menus showing instantaneously when moused over.
	
	// HIDE MENUS ON DOCUMENT CLICK: Try uncommenting this, and perhaps set hideDelay to zero:
	//hideDocClick = true;
	
	// You can assign 'oncreate' events to specific menus. By default, the script has only one for
	// the root menu that shows it when it is created. You may wish to change it to something like the
	// following, which uses the animation function to show the menu, or delay its show altogether.
	//menu.root[0].oncreate = function() { pMenu.doVis('root', true) }

	// ******************** MENU EFFECTS ********************
	//
	// Now you've created a basic menu object, you can add optional effects like borders and
	// shadows to specific menus. You can remove this section entirely if you want, the
	// functions called are found at the bottom of this file.
	
	
	
	// BORDER: Added to all menus in a named object using a specified ItemStyle. The syntax is:
	//  addMenuBorder(menuObject, ItemStyle,
	//   opacity of border, 'border colour', border width, 'padding colour', padding width);
	// Opacity is a number from 0 to 100, or null for solid colour (just like the ItemStyles).
	
	addMenuBorder(pMenu, window.subBlank,
	 null, '#666666', 1, '#CCCCDD', 2);
	
	
	
	// DROPSHADOW: added to specific ItemStyles again. The syntax is similar, but later on you
	// pass arrays [...] for each layer of the shadow you want. I've used two grey layers
	// here, but you can use as many or as few as you want. The syntax for the layers is:
	//  [opacity, 'layer colour', X offset, Y offset, Width Difference, Height difference]
	// Opacity is from 0 to 100 (or null to make it solid), and the X/Y offsets are the
	// distance in pixels from the menu's top left corner to that shadow layer's corner.
	// The width/height differences are added or subtracted to the current menu size, for
	// instance the first layer of this shadow is 4px narrower and shorter than the menu
	// it is shadowing.
	
	
	addDropShadow(pMenu, window.subM,

	// ANIMATION SETTING: We add this to the 'pMenu' menu object for supported browsers.
	// IE4/Mac and Opera 5/6 don't support clipping, and Mozilla versions prior to 1.x (such as
	// Netscape 6) are too slow to support it, so I'm doing some browser sniffing.
	// If you don't want animation, delete this entirely, and the menus will act normally.
	// Change the speed if you want... it's the last number, between -100 and 100, and is
	// defined as the percentage the animation moves each frame (defaults are 10 and 15).
