jquery - ドロップ可能でソート可能なjQuery

Question

私のフィドル: http://jsfiddle.net/Yc9WY/42/

ここに表示されるのは 2 つのグループで、それぞれに 3 つのドロップ可能なコンテナーが定義されています。イベントをグループ 1 からグループ 2、および任意のスロットに移動できます。これはうまくいきます。

グループがいっぱいになったら、イベントを上下に移動してそのグループを並べ替える機能をユーザーに提供したいと思います。ただし、必要に応じて、イベントをグループから移動できる必要があります。

並べ替え可能なライブラリの統合を開始したところにコメント アウトされたコードが表示されますが、奇妙な動作が発生しています。

注：ドラッグ可能/ドロップ可能をソート可能のみに置き換えることはできません。イベントがグループ 1 のスロット 1 と 3 に存在できるように、明示的に定義されたドロップ可能領域 (グループごとに 3 つ) が必要です。

これが私のコードです

$(document).ready(function() {

// $(".sort").sortable({
//     revert: true
// });

$(".drag").draggable({
    //connectToSortable: ".sort",
    revert: true
    //helper: clone
});

$(".sort").droppable({
    drop: function(event, ui) {

        if (!($(this).children(".drag").size() == 1)) {
            $(this).append(ui.draggable);

            ui.draggable.css({
                left: 0,
                top: 0
            });
        }
    }

});
});

<div>Group 1:
<ul class="parent">
    <li class="sort"><a href="" class="drag">event 1</a></li>
    <li class="sort"><a href="" class="drag">event 2</a></li>
    <li class="sort"></li>
</ul>
</div>
<div>
Group 2
<ul class="parent">
    <li class="sort"></li>
    <li class="sort"><a href="" class="drag">event 3</a></li>
    <li class="sort"><a href="" class="drag">event 4</a></li>
</ul>
</div>

私はこれに本当に苦労しています、ありがとう！
