<h2>Setting Up the HTML</h2> |
|
|
41 |
|
|
|
42 |
<p> |
|
|
43 |
Begin by including the <a href="../cssgrids/index.html#dependencies">CSS Grids dependencies</a> and grid |
|
|
44 |
markup (this example uses a 2 column version of the |
|
|
45 |
<a href="../cssgrids/cssgrids-fluid.html">Fluid Page Template</a> with a 160px left column). |
|
|
46 |
Add the markup for the menu to the left column of the grid. |
|
|
47 |
</p> |
|
|
48 |
<p> |
|
|
49 |
<strong>Note:</strong> be sure to add the <code>yui3-skin-sam</code> classname to the |
|
|
50 |
page's <code><body></code> element or to a parent element of the widget in order to apply |
|
|
51 |
the default CSS skin. See <a href="http://yuilibrary.com/yui/docs/tutorials/skins/">Understanding Skinning</a>. |
|
|
52 |
</p> |
|
|
53 |
<pre class="code prettyprint"><body class="yui3-skin-sam"> <!-- You need this skin class --></pre> |
|
|
54 |
|
|
|
55 |
|
|
|
56 |
<p> |
|
|
57 |
The root menu of menus built using the MenuNav Node Plugin can have a verical or horizontal |
|
|
58 |
orientation. The default orientation for menus is vertical, but can be easily switched to |
|
|
59 |
horizontal by applying a class of <code>yui3-menu-horizontal</code> to the node representing the |
|
|
60 |
root menu's bounding box, as illustrated below: |
|
|
61 |
</p> |
|
|
62 |
|
|
|
63 |
<pre class="code prettyprint"><div id="productsandservices" class="yui3-menu yui3-menu-horizontal"><!-- Bounding box --> |
|
|
64 |
<div class="yui3-menu-content"><!-- Content box --> |
|
|
65 |
<ul> |
|
|
66 |
<!-- Menu items --> |
|
|
67 |
</ul> |
|
|
68 |
</div> |
|
|
69 |
</div></pre> |
|
|
70 |
|
|
|
71 |
|
|
|
72 |
<p> |
|
|
73 |
To render each menu label in the horizontal menu as a menu button, add the class |
|
|
74 |
<code>yui3-menubuttonnav</code> to the node representing the root menu's bounding box, as |
|
|
75 |
illustrated below: |
|
|
76 |
</p> |
|
|
77 |
|
|
|
78 |
<pre class="code prettyprint"><div id="menu-1" class="yui3-menu yui3-menu-horizontal yui3-menubuttonnav"><!-- Bounding box --> |
|
|
79 |
<div class="yui3-menu-content"><!-- Content box --> |
|
|
80 |
<ul> |
|
|
81 |
<!-- Menu items --> |
|
|
82 |
</ul> |
|
|
83 |
</div> |
|
|
84 |
</div></pre> |
|
|
85 |
|
|
|
86 |
|
|
|
87 |
<p> |
|
|
88 |
Next, wrap the text node of each menu label of the root menu in an |
|
|
89 |
<code><em></code> element: |
|
|
90 |
</p> |
|
|
91 |
|
|
|
92 |
<pre class="code prettyprint"><div id="menu-1" class="yui3-menu yui3-menu-horizontal yui3-menubuttonnav"><!-- Bounding box --> |
|
|
93 |
<div class="yui3-menu-content"><!-- Content box --> |
|
|
94 |
<ul> |
|
|
95 |
|
|
|
96 |
<li> |
|
|
97 |
<a class="yui3-menu-label" href="#submenu-1"><em>Submenu Label</em></a> |
|
|
98 |
<div id="submenu-1" class="yui3-menu"> |
|
|
99 |
<div class="yui3-menu-content"> |
|
|
100 |
|

<h2>Initializing the Menu</h2> |
|
|
114 |
<p> |
|
|
115 |
With the menu markup in place, retrieve the Node instance representing the root |
|
|
116 |
menu (<code><div id="productsandservices"></code>) and call the |
|
|
117 |
<a href="http://yuilibrary.com/yui/docs/api/classes/Node.html#method_plug"><code>plug</code></a> |
|
|
118 |
passing in a reference to the MenuNav Node Plugin. |
|
|
119 |
</p> |
|
|
120 |
|
|
|
121 |
<pre class="code prettyprint">// Call the "use" method, passing in "node-menunav". This will load the |
|
|
122 |
// script and CSS for the MenuNav Node Plugin and all of the required |
|
|
123 |
// dependencies. |
|
|
124 |
|
|
|
125 |
YUI().use('node-menunav', function(Y) { |
|
|
126 |
|
|
|
127 |
// Retrieve the Node instance representing the root menu |
|
|
128 |
// (<div id="productsandservices">) and call the "plug" method |

|
|
130 |
|
|
|
131 |
var menu = Y.one("#productsandservices"); |
|
|
132 |
|
|
|
133 |
menu.plug(Y.Plugin.NodeMenuNav); |

<em>Note:</em> In keeping with the |
|
|
140 |
<a href="http://developer.yahoo.com/performance/">Exceptional Performance</a> |
|
|
141 |
team's recommendation, the script block used to instantiate the menu will be |
|
|
142 |
<a href="http://developer.yahoo.com/performance/rules.html#js_bottom">placed at the bottom of the page</a>. |
|
|
143 |
This not only improves performance, it helps ensure that the DOM subtree of the |
|
|
144 |
element representing the root menu |
|
|
145 |
(<code><div id="productsandservices"></code>) is ready to be scripted. |
