// *** START EDITING HERE, READ THIS SECTION CAREFULLY! ***
//
//
// Before you start, make sure you've read the "Conditions Of Use" in this HTML document
// or on my site. Anyway, this menu script is split up into several sections. They are:
//
// (1) ITEMSTYLES - These define the colour and size of menu items. Required to run.
// (2) MENU DATA - These specify the text and links in the menu. Required to run.
// (3) MENU EFFECTS - Want to remove, or change borders, shadows and animation? Edit them here,
//     or you can delete this section entirely to remove extra effects.
// (4) EVENTS - Activate the menu(s), and choose creation mode (Dynamic / Fast) etc. I recommend
//     you read it, but you only really need to change it if you want multiple menus on one page,
//     or are trying to combine this with other JavaScripts. Required to run.
// (5) OPTIONAL CODE - Extra features like adding clicking to 'sm:' items or status messages on
//     mouseover. Animation/effects functions are here too. You can skip or delete this entirely.
// (6) FRAMESET README - If you're using a frameset, read this, it explains what you need to do.
// *** (1) ITEMSTYLES ***
//
// First of all we must create ItemStyles to use in the menu. ItemStyles are a collection of
// dimensions, colours, and font/border stylesheet class names that you can 'apply' to menus
// and items later on for a consistent look. The (somewhat lengthy) syntax is:
//
// styleName = new ItemStyle(length of items, spacing after items, 'popout indicator HTML',
//  popout indicator position, padding of text within item, 'out background colour or image
//  filename', 'hover background colour or filename', 'out text stylesheet class', 'hover text class',
//  'out border stylesheet class', 'hover border class', out opacity percentage or null to make
//  it fully opaque, hover opacity percentage or null, 'CSS mouse cursor for normal items',
//  'CSS cursor for sm: and blank items');
//
// One thing that needs explaining is the popout indicator position -- you pass a positive
// integer to position it from the left of the item, and a negative integer to position it from
// the right edge of the item -- see the example code below if that doesn't make much sense.
// Pass an empty string '' as the over or out background for a transparent background.
// If you pass 'hand' as a cursor, the script automatically translates it to 'pointer' for NS6.
// All stylesheet text/border classes come from the <STYLE> tag in this document, you can change
// the font and border colours and styles used there.
//
// Here are some examples used in this menu demo, read through and see how they're formatted,
// then try tweaking some of the numbers and refreshing the page:
// '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.
var hBar = new ItemStyle(100, 2, '', 2, 1, '#0f3e64', '#0f3e64', 'highText', 'highText', '#a3c5e0', '#a3c5e0', 100, 100, 'hand', 'default');
// The 'sub Menu' items: 22px long, 0px spacing, a 'greater than' sign for a popout indicator
// (you may wish to use an image tag?), the popout indicator is positioned 15px from the right
// edge of the item, items have 3px padding, some colours, it uses 'lowText' as the dimmed text
// class but 'highText' when it is moused over, and 'itemBorder' as the border stylesheet class.
// No opacity is used, and they have the same cursors as the above ItemStyle.
var subMnorm = new ItemStyle(28, 1, '&gt;', -15, 3, '#0f3e64', '#336666', 'lowText', 'highText', 'itemBorder', 'itemBorder', 90, 100, 'hand', 'default');

var subM = new ItemStyle(40, 1, '&gt;', -15, 3, '#0f3e64', '#336666', 'lowText', 'highText', 'itemBorder', 'itemBorder', 90, 100, 'hand', 'default');
// 'subBlank' is similar, but has an 'off' border the same colour as its background so it
// appears borderless when dim, and 1px spacing between items to show the hover border.
var subBlank = new ItemStyle(40, 1, '&gt;', -15, 3, '#0f3e64', '#669999', 'lowText', 'highText', '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.
var button = new ItemStyle(28, 1, '&gt;', -15, 3, '#0f3e64', '#a3c5e0', 'lowText', 'highText', 'itemBorder', 'itemBorder',100, 100, 'hand', 'default');

var button2 = new ItemStyle(28, 1, '&gt;', -15, 3, '#0f3e64', '#a3c5e0', 'lowText', 'highText', 'itemBorder', 'itemBorder', 100, 100, 'hand', 'default');




// *** (2) MENU DATA ***
//
// Read this section VERY CAREFULLY, it explains how to arrange and tweak the menus themselves.
// To use this script you must create one or more PopupMenu() objects, that will contain all
// the menu data and settings used. This demo contains one, named 'pMenu', although you can
// have as many totally separate menus as you want on one page.
//    Next we add menus and items to the object, using its startMenu() and addItem()
// commands. Each menu object MUST contain one menu named 'root', which is the first, always
// visible menu. The syntax of the startMenu() command is:
//
// startMenu('menu name', Vertical menu (true/false)?, left, top, width, default ItemStyle
//  for items in this menu, optional parent frame/window or layer in which this menu resides);
//
// In order, the parameters are a name for the menu like 'root' or 'mFile', which you can use to
// refer to this menu from other menus, to pop it out.
//    Next, pass 'true' if you want this to be a vertical stacked menu or 'false' if you want this
// to be a horizontal menu bar. You can orientate each menu differently this way.
//   The Left and Top positions allow you to locate this menu either absolutely from the page or
// relative to menu item that pops it out. If you want to offset this menu from the item that pops
// it out, set the positions as NUMBERS, e.g. 130, 10 would put the upper-left corner of this menu
// 130px across and 10px down from the upper-left corner of the item that popped it out.
//   If you put '130', '10' as positions in QUOTES, you can position the menu from the upper-left
// corner of the whole page. These strings can also include formulae to centre or scroll the menu,
// examples are included later on. Note: the 'root' menu is always positioned from the page corner.
//    The 'width' depends on the orientation of the menu -- for vertical menus it's the width,
// for horizontal menus it is the height. Basically, it's the constant dimension for all the items.
//    The parent window or layer parameter is optional, if not specified the current window is
// used -- this example does not use frames. See the frameset example file if you're using them,
// they are strings that when evaluated return a reference, like 'window.top'.
//
// Once you have created a menu, you add items to that menu using the addItem() command.
// You must give it THREE compulsory parameters: 1) The HTML/text to display in the item. 2) The
// menuname/filename/URL the item activates. 3) The action type or target frame of that item.
// All other parameters are optional -- you can override the menu's default ItemStyle with the
// item's own, and optionally override that was well by specifying a list of parameters in the
// same order as an ItemStyle, to give each item its own dimensions / colours etc.
// See the example menu below for an example of these extras...
//
// addItem('Text', 'URL or menuname', 'action type', optional ItemStyle, length, spacing,
//  'popout indicator', popout indicator position, etc... in the same order as ItemStyles);
//
// The third parameter, 'action type', tells the script what to do with the second parameter.
// You can tell the script to load a file in the current window or a particular frame, tell it
// to pop out a menu, or tell it to run a JavaScript command. You do these like this:
//
// addItem('Text', 'file.html', ''); //blank means opens up 'file.html' in the current window.
// addItem('Text', 'file.html', 'parent.content');  //opens 'file.html' in a frame named 'content'.
// addItem('Text', 'menuName', 'sm:');  //pops out another submenu called 'menuName'.
// addItem('Text', 'alert("Hello")', 'js:');  //runs a JavaScript command when clicked.
//
// Frame names should be valid JavaScript syntax, e.g. 'top.frameName' or 'parent.popupWin',
// evaluated from the the window containing the main script (this one). Also, this system means
// 'sm:' items aren't normally clickable. If you do want to add click or mouseover actions to
// items, see the "Optional Code" section of the script below.
// 
// See the example below if this seems complicated, it's quite easy once you get the hang of it.
// Thanks to Martin J. Cole for originally suggesting the syntax!
// If you want more information, there's a FAQ (Frequently Asked Questions) section on my
// site: http://www.twinhelix.com, on the 'Popup Menus' page, or try the 'Site Forums" perhaps.
// A PopupMenu() object must be passed its own name so it can reference itself when the menu
// is active. We also use a 'with' block to work with its properties and functions below.

// BORDERS AND DROPSHADOWS:
//
// Here's the menu border and dropshadow functions we call above. Edit ot delete if you're
// not using them. Basically, they assign a string to pMenu.menu.menuName[0].extraHTML, which
// is written to the document with the menus as they are created -- the string can contain
// anything you want, really. They also adjust the menu dimensions and item positions
// to suit. Dig out the Object Browser script and open up "pMenu" for more info.
