Thank you for your PR. I previously encountered an issue during the multi-select cloning process. Could you add a case for multi-select cloning?

From you, I think there will be many more cases that should be resolved after the swap and multiDrag are enabled, not only between multiDrag and clone.

Also, I would like to know why useDraggable operates on dom elements. I'm not sure about the effect of the dom operations. 😢

[Alfred-Skyblue]

In developing the multiDrag feature, I've encountered numerous issues, especially with the clone functionality. This has been a challenge I haven't yet overcome, which is why I haven't released the multiDrag feature.

I didn't quite understand what you meant by this statement.

呃，我英文太水了，还是用中文说吧。

我的意思是，当启用 swap 和 multiDrag 后，所有基础功能 + 这两个插件对应被启用的情况应该都需要考虑，会有很多复杂的情况，而不仅仅是 multiDrag + clone ...

第二个我没有表示清楚问题如下：

在 useDraggable 里有一些 DOM 操作，比如

vue-draggable-plus/src/useDraggable.ts

Line 223 in afba00a

currentNodes?.some((node, index) => {

先叠甲，我 sortablejs 用的很少，如果问题有冒犯，烦请见谅
我不是要讨论这行代码解决的问题，而是好奇为什么需要进行 DOM 操作，我会觉得对 sortablejs 进行封装，只要处理数据即可，为什么即要处理数据，又要处理 dom。

以上是原提问的意思。

在用中文重新梳理提问的时候，我突然觉得是不是因为当前写法，传入的 dataList 和 dom 结构在变化过程中不实时一一对应，所以才需要既处理 data 又处理 dom 呢？( 无意冒犯，是我真太菜没看懂 😢

[Alfred-Skyblue]

vue-draggable-plus/src/useDraggable.ts

Line 223 in afba00a

currentNodes?.some((node, index) => {

这里是处理了 #202 的问题，导致的如果拖拽回原位的情况下，会导致vnode错误

其他地方操作dom，比如：

vue-draggable-plus/src/useDraggable.ts

Line 205 in afba00a

removeNode(item)

此处是为了处理动画问题，因为动画是基于dom操作的

我的意思是，当启用 swap 和 multiDrag 后，所有基础功能 + 这两个插件对应被启用的情况应该都需要考虑，会有很多复杂的情况，而不仅仅是 multiDrag + clone

我当初在完成 multiDrag 功能的时候，处理了很多问题，在最后一个环节，我发现我使用 sortablejs 很难处理多个元素克隆的问题，当然单纯的克隆不是问题，问题是克隆过后带来的副作用，我暂时没有办法处理它，这也是我当时没有添加这个功能的原因

那我可以先自己尝试处理更多的 cases，看最终会不会碰到你之前碰到的问题。

好的，感谢您的努力
