title: Animate offset with jquery
body: <p>I'm doing this :</p>
  
  <pre><code>source.offset({ top: top + 10 + (current)*60 , left: left + 10 });
  </code></pre>
  
  <p>What I would like to do is to animate the move. So I've done :</p>
  
  <pre><code>source.animate({left: left + 10, top:top + 10 + (current)*60}, 500, function() {    // Animation complete.});
  </code></pre>
  
  <p>But it's not going to the right place. Although with the first version it was ok.</p>
  
  <p>What am I doing wrong ?</p>
  
  <p>Thanks for your help</p>
