+
+ <h3>Creating the Rounded Corner HTML</h3>
+<p>
+One way to add rounded corners 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 rounded corner is created by applying a background image to a <code><div></code>.
+A class name identifying the corner will be added to each <code><div></code>.
+The <code><div></code>s used to create the right corners will be nested inside the
+<code><div></code>s used to create the left corners, and each <code><div></code>
+for the left corners will have an additional class name of <code>yui-menu-corner</code>. The
+template for each set of rounded corners comes together as follows:
+</p>
+
+<textarea name="code" class="HTML" cols="60" rows="1">
+<!-- top-left and top-right corners -->
+<div class="yui-menu-corner yui-menu-corner-tl"><div class="yui-menu-corner-tr"></div></div>
+
+<!-- bottom-left and bottom-right corners -->
+<div class="yui-menu-corner yui-menu-corner-bl"><div class="yui-menu-corner-br"></div></div>
+</textarea>
+
+<p>
+The <code><div></code>s for each corner is 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> and
+<a href="../../api/Node.html#method_insertBefore"><code>insertBefore</code></a>
+methods to add the rounded corners <code><div></code>s to the bounding box of 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) {
+
+ // Add decorator elements used to create the rounded corners to the
+ // bounding box of each submenu.
+
+ // Insert the first decorator before the submenu's content box
+ node.insertBefore(Y.Node.create('<div class="yui-menu-corner yui-menu-corner-tl"><div class="yui-menu-corner-tr"></div></div>'), node.get("children").item(0));
+
+ // Insert the second decorator after the submenu's content box
+ node.appendChild(Y.Node.create('<div class="yui-menu-corner yui-menu-corner-bl"><div class="yui-menu-corner-br"></div></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>Create the Rounded Corner Background Image</h3>
+<p>
+For performance, each rounded corner <code><div></code> uses the same image as its
+background image, but only reveals the relevant section of the image via the
+<code>background-position</code> property. The complete image is as follows:
+</p>
+
+<img src="assets//round.png" width="200" height="6" alt="Image used as the background image for the DIV elements used to create rounded corners">
+
+<h3>Styling the Rounded Corner HTML</h3>
+<p>
+With the rounded corner elements appended to each submenu, the next step is to define
+the styles that create the rounded corner effect. Start by overriding the values for
+<code>border</code> and <code>padding</code> specified for the content box of each submenu in the
+Sam skin CSS. The top and bottom borders are set to 0, since both borders will be drawn by the
+background image used to create the rounded corners. The top and bottom padding will be created by
+setting the height of each <code><div></code> inside the
+<code><div class="yui-menu-corner"></code>.
+</p>
+
+<textarea name="code" class="CSS" cols="60" rows="1">
+/*
+ Overide the values for border and padding specified for the content box of each submenu in
+ the Sam skin CSS. The top and bottom borders are set to 0, since both borders will be drawn
+ by the background image used to create the rounded corners. The top and bottom padding
+ will be created by setting the height of each <div> inside the
+ <div class="yui-menu-corner">.
+*/
+
+#productsandservices .yui-menu .yui-menu-content {
+
+ border-top: 0;
+ border-bottom: 0;
+ padding: 0;
+
+}
+</textarea>
+
+<p>
+Next, define the styles for each corner element. The <code><div></code>s for the top-left
+and bottom-left corners define a right margin that will provide space for the their inner
+<code><div></code>s to fill using a negative right margin. Each inner
+<code><div></code> will define a left margin to reveal the background image applied to
+its parent <code><div></code>.
+</p>
+<textarea name="code" class="CSS" cols="60" rows="1">
+.yui-menu-corner {
+
+ margin-right: 4px; /* Reserve space for the top-right and bottom-right corners. */
+
+ /* The background image (sprite) for the top-left and bottom-left corners. */
+ background: url(assets/round.png) no-repeat;
+
+}
+
+.yui-menu-corner div {
+
+ height: 4px;
+
+ margin: 0 -4px 0 4px; /* Use a negative right margin to move the <div> into
+ the right margin of the parent element
+ (<div class="yui-menu-corner">) to draw the top-right
+ and bottom-right corners.
+
+ Apply a left margin to reveal the background image
+ applied to the parent element for the top-left and
+ bottom-left corners. */
+
+ /* The background image (sprite) for the top-right and bottom-right corners. */
+ background: url(assets/round.png) no-repeat;
+
+ _position: relative; /* Necessary to get negative margins working in IE 6
+ (Standards Mode and Quirks Mode and IE 7 (Quirks
+ Mode only). */
+
+ _font-size: 0; /* Necessary to collapse the height of the <div> in IE 6
+ (Standards Mode and Quirks Mode and IE 7 (Quirks Mode only) so
+ that it renders at 4px tall. */
+
+}
+</textarea>
+
+
+<p>
+The last step is to simply set <code>background-position</code> property for the bottom-left,
+top-right, and bottom-right corner elements to reveal the corresponding section of the corner
+background image.
+</p>
+<textarea name="code" class="CSS" cols="60" rows="1">

+ Set the "background-position" property for the bottom-left, top-right, and
+ bottom-right corner elements to reveal the corresponding section of the corner
