<h3 id="adding-plugins-to-a-delegate-instance">Adding Plugins to a Delegate instance</h3>
<p><code>DD.Delegate</code> provides a reference to the <code>dd</code> instance so you can plug into the underlying <code>dd</code> with <code>del.dd.plug()</code>.
This allows you to use DD plugins on a Delegate instance, as well as provides the ability to write plugins for Delegate itself.
</p>
<h3 id="constrain-plugin">Constrain Plugin</h3>
<p>Here is how you would add the constrain plugin to a <code>DD.Delegate</code> instance.</p>
<pre class="code prettyprint">YUI().use('dd-delegate', 'dd-constrain', function(Y) {
var del = new Y.DD.Delegate({
container: '#demo',
nodes: 'li'
});
del.dd.plug(Y.Plugin.DDConstrained, {
constrain2node: '#play'
});
});</pre>
<h3 id="ddproxy-plugin">DDProxy Plugin</h3>
<p>Here is how you would add the dd-proxy plugin to a <code>DD.Delegate</code> instance.</p>
<pre class="code prettyprint">YUI().use('dd-delegate', 'dd-proxy', function(Y) {
