jQuery UI sortable: How to exclude items from connected lists?

问题

I have two lists (left/right coloumn) which are connected, so I can drag&drop items from one column (left) to the other (right).

How can I exclude specific items from list1 (left) that should NOT be draggable to list2 (right) while keeping the functionality to drag&drop them inside their source-list?

I used the following and it worked for me. Had same requirement.

$("ul#YourLeftListID li").each(function () {
            if ($(this).text() == 'None') {
                $(this).draggable({ disabled: true })
            }
        });

Hope this helps.
