title: Jquery UI sortable - sort only on drop event
body: <p>I want to disable sorting of items when item is dragged. Only after the drop has been completed the items must sort accordingly.</p>
  
  <pre><code>     $( "#sortable" ).sortable({
  
          tolerance: 'pointer',
          revert: 'invalid',
          forceHelperSize: true,
          scroll: true,
          forcePlaceholderSize: true,
          placeholder: 'ui-state-highlight',
          helper: 'clone',
          containment: 'parent',
          cursor: 'move',        
          distance: 5,
          opacity: 0.3,
      });
  </code></pre>
