jQuery draggable: Stop dragging when mouse out of parent

Question

Please check out this jsFIDDLE

<div id="wrapper">
    <div class="item">
        <div class="button_area"></div>
        <div class="icon"></div>
    </div>

    <div class="item">
        <div class="button_area"></div>
        <div class="icon"></div>    
    </div>
</div>​

This is the html code, and I am dragging the .button_area:

$('.button_area').draggable({});

It is working as it is suppused to except for one thing. When I click on the red area (in the second yellow square) and start dragging toward left (first yellow square) I want it to stop the drag process when the mouse gets over second yellow square (parent).... not the draggable object (helper)... THE MOUSE.

You must only modify your jquery this way

$( ".button_area" ).draggable({
drag: function(event, ui) { 
  if(my_condition) 
      return false; }
  });​

Tip!

one example would be something along this:

$( ".button_area" ).draggable({
drag: function(event, ui) { 
  if($('.button_area').offset().left > 50) 
  { 
     $( '.button_area' ).draggable( 'option',  'revert', true ).trigger( 'mouseup' );
  } 
 }
 });​
