+
+ <h3>Creating the Shadow HTML</h3>
+<p>
+One way to add shadows to submenus is to append decorator elements to the node representing a
+submenu's bounding box. As the name implies, decorator elements add no semantic value to the
+markup, but enable additional styles to be applied. When adding any decorator elements to create
+effects like shadows or rounded corners, always add those elements via JavaScript, since it is only
+when JavaScript is enabled that a menu's markup is transformed in a drop-down menu system via the
+MenuNav Node Plugin.
+</p>
+
+<p>
+Each shadow will be represented in HTML as a single <code><div></code> element with a class
+of <code>yui-menu-shadow</code> applied, and can easily be created by passing a string of HTML
+to Node's <a href="../../api/Node.html#method_create"><code>create</code></a> method. Use the
+<a href="../../api/Node.html#method_queryAll"><code>queryAll</code></a> method to
+retrieve Node instances for each submenu, and the
+<a href="../../api/Node.html#method_appendChild"><code>appendChild</code></a> method to add the
+shadow to each submenu.
+</p>
+
+<textarea name="code" class="JScript" cols="60" rows="1">
+// Call the "use" method, passing in "node-menunav". This will load the
+// script and CSS for the MenuNav Node Plugin and all of the required
+// dependencies.
+
+YUI({base:"../../build/", timeout: 10000}).use("node-menunav", function(Y) {
+
+ // Retrieve the Node instance representing the root menu
+ // (<div id="productsandservices">)
+
+ var menu = Y.Node.get("#productsandservices");
+
+
+ // Use the "queryAll" method to retrieve the
+ // Node instances representing each submenu.
+
+ menu.queryAll(".yui-menu").each(function (node) {
+
+ // Append a shadow element to the bounding box of each submenu
+
+ node.appendChild(Y.Node.create('<div class="yui-menu-shadow"></div>'));
+
+ });
+
+
+ // Call the "plug" method of the Node instance, passing in a reference to the
+ // MenuNav Node Plugin.
+
+ menu.plug(Y.Plugin.NodeMenuNav);
+
+});
+</textarea>
+<em>Note:</em> In keeping with the
+<a href="http://developer.yahoo.com/performance/">Exceptional Performance</a>
+team's recommendation, the script block used to instantiate the menu will be
+<a href="http://developer.yahoo.com/performance/rules.html#js_bottom">placed at the bottom of the page</a>.
+This not only improves performance, it helps ensure that the DOM subtree of the
+element representing the root menu
+(<code><div id="productsandservices"></code>) is ready to be scripted.
+</p>
+
+<h3>Styling the Shadow HTML</h3>
+<p>
+With the shadow element appended to each submenu, the next step is to define the style for the
+shadow. The shadows in this example will be 12% alpha transparent black, and offset from the left,
+bottom, and right edges of each submenu's content box by 3px. To create this effect, start by
+setting the <code>position</code> property to <code>absolute</code> and the <code>z-index</code>
+property to <code>-1</code>. This will position each submenu's shadow behind its content box. For
+the 12% alpha transparent black color, set the <code>background-color</code> to <code>#000</code>
+and <code>opacity</code> property to <code>.12</code>.
+</p>
+
+<p>
+Next, set the both the <code>width</code> and <code>height</code> properties to <code>100%</code>
+so that the dimensions of the <code>shadow</code> match that of each submenu's bounding box.
+(<em>Note:</em> Setting the <code>height</code> property to <code>100%</code> won't work in IE 6
+Strict Mode unless the element's parent element has a height defined. For this reason the the
+MenuNav Node Plugin automatically sets the <code>width</code> and <code>height</code> properties of
+each submenu's bounding box to the values of its <code>offsetWidth</code> and
+<code>offsetHeight</code> properties before it is made visible.)
+</p>
+
+<p>
+To create the three-sided effect for the shadow, set the <code>padding</code> property to
+<code>1px 3px 0 3px</code>. As the CSS Box Model specifies that the value for padding is used to
+calculate the total width of of an element, the addition of the padding to the shadow makes the
+rendered width of the shadow 6px wider (100% + 6px) and 1px taller (100% + 1px) than that of each
+submenu's bounding box. Finally, setting the <code>top</code> property to <code>2px</code> and
+the <code>left</code> property to <code>-3px</code> will position the shadow so that its offset
+from the left, bottom, and right edge of each submenu's content box by 3px.
+</p>
+
+<textarea name="code" class="CSS" cols="60" rows="1">
+.yui-menu-shadow {
+
+ position: absolute;
+ z-index: -1;
+ top: 2px;
+ left: -3px;
+
+ background-color: #000;
+ opacity: .12;
+ filter: alpha(opacity=12); /* For IE since it doesn't implement the CSS3
+ "opacity" property. */
+
+ padding: 1px 3px 0 3px;
+ width: 100%;
+ height: 100%;
+
+}
+</textarea>
+
+<p>
+Lastly, it is necessary to modify the position and dimensions of the <code><iframe></code>
+shim, otherwise <code><select></code> elements will poke through each submenu's shadow in
+IE 6. Start by setting the <code>z-index</code> property to <code>-2</code> so that the
+<code><iframe></code> shim is behind the shadow element. Next, set the <code>padding</code>
+property to <code>3px 3px 0 3px</code>. The core CSS file for MenuNav already sets the
+<code>height</code> and <code>width</code> properties to <code>100%</code>, so the addition of the
+padding will result in the calculated width and height of the <code><iframe></code> shim
+being 100% + 6px and 100% + 3px respectively — enough to shim the shadow. Lastly, setting the
+<code>left</code> property to <code>-1</code> syncs the left edge of the
+<code><iframe></code> with that of the shadow.
+</p>
+
+<textarea name="code" class="CSS" cols="60" rows="1">
+#productsandservices .yui-menu .yui-shim {
+
+ z-index: -2; /* Place the iframe shim behind the shadow element */
+
+ /*
+ Adjust the dimensions of the <iframe> shim to match the shadow,
+ otherwise <select> elements will poke through the shadow.
+ */
+
+ left: -3px;
+ padding: 3px 3px 0 3px;
