<h2 class="first">Basic Drag and Drop</h2>
<p>The <a href="http://developer.yahoo.com/yui/dragdrop/">YUI Drag and Drop</a> Utility lets you make HTML elements draggable.</p>
<p>For this example, we will enable drag and drop for the three <code>&lt;div&gt;</code> elements.</p>
<p>Create the <code>demo</code> elements:</p>
<div id="syntax1" class="yui-syntax-highlight"><div class="numbers"><pre class="html4strict" style="font-family:monospace;"><ol><li class="li1"><div class="de1"><span class="sc2">&lt;<span class="kw2">div</span> <span class="kw3">id</span><span class="sy0">=</span><span class="st0">&quot;dd-demo-1&quot;</span> <span class="kw3">class</span><span class="sy0">=</span><span class="st0">&quot;dd-demo&quot;</span>&gt;&lt;<span class="sy0">/</span><span class="kw2">div</span>&gt;</span></div></li><li class="li1"><div class="de1"><span class="sc2">&lt;<span class="kw2">div</span> <span class="kw3">id</span><span class="sy0">=</span><span class="st0">&quot;dd-demo-2&quot;</span> <span class="kw3">class</span><span class="sy0">=</span><span class="st0">&quot;dd-demo&quot;</span>&gt;&lt;<span class="sy0">/</span><span class="kw2">div</span>&gt;</span></div></li><li class="li1"><div class="de1"><span class="sc2">&lt;<span class="kw2">div</span> <span class="kw3">id</span><span class="sy0">=</span><span class="st0">&quot;dd-demo-3&quot;</span> <span class="kw3">class</span><span class="sy0">=</span><span class="st0">&quot;dd-demo&quot;</span>&gt;&lt;<span class="sy0">/</span><span class="kw2">div</span>&gt;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="html4strict" style="font-family:monospace;"><span class="sc2">&lt;<span class="kw2">div</span> <span class="kw3">id</span><span class="sy0">=</span><span class="st0">&quot;dd-demo-1&quot;</span> <span class="kw3">class</span><span class="sy0">=</span><span class="st0">&quot;dd-demo&quot;</span>&gt;&lt;<span class="sy0">/</span><span class="kw2">div</span>&gt;</span>

<div id="dd-demo-2" class="dd-demo"></div>
<div id="dd-demo-3" class="dd-demo"></div></textarea></div>
<p>Now we create the instances of <code>YAHOO.util.DD</code>, passing the element ids or references for our demo elements.</p>
