title: Sort items into fixed container with jQuery ui sortable
body: <p>I have a problem with my sortable list. I have two container which both have sortable list inside. One of the two container have a fixed position. While I can move an item from the fixed container to the other, I cannot move an item from the not-fixed container to the fixed one.</p>
  
  <pre><code>$('ul').sortable({
    connectWith: $('ul'),
    items: '&gt; li'
  });
  
  .fixed {
    position:fixed;
    left:100px;
    top:0;
  }
  
  &lt;div class="fixed"&gt;
    &lt;ul&gt;
      &lt;li&gt;f1&lt;/li&gt;
      &lt;li&gt;f2&lt;/li&gt;
      &lt;li&gt;f3&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div class="not-fixed"&gt;
    &lt;ul&gt;
      &lt;li&gt;nf1&lt;/li&gt;
      &lt;li&gt;nf2&lt;/li&gt;
      &lt;li&gt;nf3&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>You can see the problem there : <a href="http://jsfiddle.net/mQP8p/" rel="nofollow">http://jsfiddle.net/mQP8p/</a></p>
  
  <p>The fixed container <strong>must</strong> be with a fixed postion (the container must follow the page vertically and horizontally)</p>
  
  <p>Does someone have seen this before?</p>
  
  <p>Thanks !</p>
