title: On gridster keep widget under mouse during drag
body: <p>I actually use gridster for drag some items.</p>
  
  <p>My container is bigger than my window, so, i have a scrollbar on the right side, as usual. Now, if i want to drag an item from the top to the bottom, I need to click on it and scroll the mouse at the same time.</p>
  
  <p>As you can see on <a href="http://jsfiddle.net/u3qQA/">this</a> fiddle,  If you take the item and you start to scroll, the item stay at his first position, you need to move the mouse for bring it to it.</p>
  
  <p>There is a way for keep the item under the mouse even if you scroll ?</p>
  
  <p>Sample html code:</p>
  
  <pre><code>&lt;div class="container"&gt;
    &lt;div class="gridster"&gt;
      &lt;ul&gt;
         &lt;li data-row="1" data-col="1" data-sizex="2" data-sizey="2"&gt;0&lt;/li&gt;
         &lt;li data-row="1" data-col="3" data-sizex="1" data-sizey="2"&gt;1&lt;/li&gt;
         &lt;li data-row="1" data-col="4" data-sizex="1" data-sizey="1"&gt;2&lt;/li&gt;
         &lt;li data-row="3" data-col="2" data-sizex="3" data-sizey="1"&gt;3&lt;/li&gt;
         &lt;li data-row="4" data-col="1" data-sizex="1" data-sizey="1"&gt;4&lt;/li&gt;
         &lt;li data-row="3" data-col="1" data-sizex="1" data-sizey="1"&gt;5&lt;/li&gt;
         &lt;li data-row="4" data-col="2" data-sizex="1" data-sizey="1"&gt;6&lt;/li&gt;
         &lt;li data-row="5" data-col="2" data-sizex="1" data-sizey="1"&gt;7&lt;/li&gt;
         &lt;li data-row="4" data-col="4" data-sizex="1" data-sizey="1"&gt;8&lt;/li&gt;
         &lt;li data-row="1" data-col="5" data-sizex="1" data-sizey="3"&gt;9&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/div&gt;
  &lt;/div&gt;
