title: How to drag items between 2 sorted lists with jQuery?
body: <p>I'm trying to implement drag/drop/sort between 2 list elements:</p>
  
  <pre><code>&lt;ul id="first"&gt;
    &lt;li&gt;item 1&lt;/li&gt;
    &lt;li&gt;item 2&lt;/li&gt;
    &lt;li&gt;item 3&lt;/li&gt;
  &lt;/ul&gt;
  
  &lt;ul id="second"&gt;
    &lt;li&gt;item 4&lt;/li&gt;
    &lt;li&gt;item 5&lt;/li&gt;
    &lt;li&gt;item 6&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>Basically I just want to be able to pass items between the lists and sort the items in each list. What's the simplest way to implement this using jQuery?</p>
