首先，看看这个，并阅读@Erez 的答案.

For a beginning, have a look at this, and read @Erez answer, too.

$(function () {
    $("#sortable1").sortable({
        connectWith: ".connectedSortable",
        remove: function (event, ui) {
            ui.item.clone().appendTo('#sortable2');
            $(this).sortable('cancel');
        }
    }).disableSelection();

    $("#sortable2").sortable({
        connectWith: ".connectedSortable"
    }).disableSelection();
});
