Justin Bull's answer让我参与其中。但是我还有一个附加要求，贾斯汀的回答不能满足要求。

以下是设置：

我刚刚复制了贾斯汀的答案，并添加了更多span.tag_cell，这样tf_div_tagsReturn就会真正溢出。这是相同的小提琴：https://jsfiddle.net/sz1fg025/

我希望将tag_cell拖到tf_div_tagsReturn外面（已经可以使用），但是我 还希望能够在tag_cell中拖动tf_div_tagsReturn（例如，好像在tf_div_tagsReturn中对其内部重新排序）。

问题是，当您将一个单元格向下/向上拖动到tf_div_tagsReturn的边界之外时，它不会像用户期望的那样自动滚动。
