<div class="exampleIntro">
<p>In this simple example you can see how to build <a href="http://developer.yahoo.com/yui/treeview/">TreeView Control</a> instance from several different sources of data:</p>
<ol>
<li>an HTML list on the page;</li>
<li>an existing TreeView instance's definition;</li>
<li>a branch of an existing TreeView instance (e.g., from one of its nodes).</li>
</ol>
</div>
<!--BEGIN SOURCE CODE FOR EXAMPLE -->
<h3>Tree from markup</h3>
<div id="markup" class="whitebg">
<ul>
<li>List 0
<ul>
<li>List 0-0
<ul>
<li>item 0-0-0</li>
<li>item 0-0-1</li>
</ul>
