<h3>Setting up the YUI Instance</h3>
<p>Now we need to create our YUI instance and tell it to load the <code>dd-drop</code> and <code>dd-constrain</code> modules.</p>
<div id="syntax3" class="yui-syntax-highlight"><div class="numbers"><pre class="javascript" style="font-family:monospace;"><ol><li class="li1"><div class="de1">YUI<span class="br0">(</span><span class="br0">)</span>.<span class="kw2">use</span><span class="br0">(</span><span class="st0">'dd-drop'</span><span class="sy0">,</span> <span class="st0">'dd-constrain'</span><span class="br0">)</span><span class="sy0">;</span></div></li></ol></pre></div><div class="nonumbers"><pre class="javascript" style="font-family:monospace;">YUI<span class="br0">(</span><span class="br0">)</span>.<span class="kw2">use</span><span class="br0">(</span><span class="st0">'dd-drop'</span><span class="sy0">,</span> <span class="st0">'dd-constrain'</span><span class="br0">)</span><span class="sy0">;</span></pre></div><textarea id="syntax3-plain">YUI().use('dd-drop', 'dd-constrain');</textarea></div>
<h3>Making the Nodes draggable</h3>
<p>Now that we have a YUI instance with the <code>dd-drop</code> module, we need to instantiate the <code>Drag</code> instance on each Drag Node.</p>
<p>In this example we are using the data config option of the drag to associate data with this Drag instance.</p>
<p>So we have set up an object literal containing information about our drag items.</p>
