jQuery UI Draggable - Handles
I can be dragged only by this handle
You can drag me around…
…but you can't drag me by this handle.
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.
