Reply to comment youtube style
<p>I'm trying to create a similar comments system to YouTube. What would be the easiest way of making a reply <code>textarea</code> appear under a comment when the button is clicked? I assume duplicating the <code>textarea</code> and making it <code>display:none</code> for each comment is not necessary.</p>

<p><strong>With textarea</strong></p>

<pre><code>&lt;div class="comment"&gt;
  &lt;p&gt;Bla bla&lt;/p&gt;
  &lt;a hred="" id="reply"&gt;Reply&lt;/a&gt;
  &lt;textarea class="reply"&gt;&lt;/textarea&gt;   
&lt;/div&gt;
</code></pre>

<p><strong>Without textarea</strong></p>

<pre><code>&lt;div class="comment"&gt;
  &lt;p&gt;Bla bla2&lt;/p&gt;
  &lt;a hred="" id="reply"&gt;Reply&lt;/a&gt;
&lt;/div&gt;
</code></pre>

<p><strong>jQuery</strong></p>

<pre><code>$('#reply').click(function(){

}
</code></pre>
