  <h1>jQuery UI Draggable</h1>
  <div id="overview">
    <h2 class="top-header">Overview</h2>
    <div id="overview-main">
        <p>The jQuery UI Draggable plugin makes selected elements draggable by mouse.</p>
<p>Draggable elements gets a class of <code>ui-draggable</code>. During drag the element also gets a class of <code>ui-draggable-dragging</code>. If you want not just drag, but drag-and-drop, see the jQuery UI Droppable plugin, which provides a drop target for draggables.</p>
<p>All callbacks (start, stop, drag) receive two arguments: The original browser event and a prepared ui object, view below for a documentation of this object (if you name your second argument 'ui'):</p>
<ul>
<li><b>ui.helper</b> - the jQuery object representing the helper that's being dragged</li>
<li><b>ui.position</b> - current position of the helper as { top, left } object, relative to the offset element</li>
<li><b>ui.offset</b> - current absolute position of the helper as { top, left } object, relative to page</li>
</ul>
<p><br />
</p>
<p>To manipulate the position of a draggable during drag, you can either <a href="http://jsbin.com/etako/edit" class="external text" title="http://jsbin.com/etako/edit">use a wrapper as the draggable helper</a> and position the wrapped element with absolute positioning, or  you can correct internal values like so: <code>$(this).data('draggable').offset.click.top -= x</code>.</p>
