draggable helper : what is it ?

Hi.

I'm experimenting with draggable/droppable. From the documentation it's not perfectly clear to me what the helper is and what is the difference between ui.draggable and ui.helper objects and by consequence what the clone option is for.

ui.helper - the jQuery object representing the helper that's being dragged

May anyone help me understand this?

Thank you in advance.

Using the draggable option helper you can decide whether the original element, a clone of it, or some other element (returned by a function) is dragged around.

So the helper option specifies which element should be draggabed around, the value of the option being a string or a function.

The ui.helper property in a draggable event contains the corresponding element, the one being dragged around.

Here's a quick demo showing all three:
