CJuiDraggable displays a draggable widget.

CJuiDraggable encapsulates the JUI Draggable plugin.

To use this widget, you may insert the following code in a view:
$this->beginWidget('zii.widgets.jui.CJuiDraggable',array(
    // additional javascript options for the draggable plugin
    'options'=>array(
        'scope'=>'myScope',
    ),
));
    echo 'Your draggable content here';

$this->endWidget();



By configuring the options property, you may specify the options that need to be passed to the JUI Draggable plugin. Please refer to the JUI Draggable API documentation for possible options (name-value pairs) and JUI Draggable page for general description and demo.
