Allow dragging only when the cursor is over a specific part of the draggable. Use the handle option to specify the jQuery selector of an element (or group of elements) used to drag the object.
Or prevent dragging when the cursor is over a specific element (or group of elements) within the draggable. Use the cancel option to specify a jQuery selector over which to "cancel" draggable functionality.
