jqueryui可拖动的可放置问题

Question

我需要一些帮助来了解这有什么问题。

将项目拖放到可放置区域（模板位置）时，它会移动到另一个位置，然后再次尝试将其拖动到正确的位置时，它会移动得更远......

例如：我将苹果和香蕉都放到可掉落区域后，如果我将香蕉靠近苹果，它会粘在一起..

拖动项目的光标移动距离项目本身很远，假设我没有设置光标位置，它会出现在我要拖动项目时鼠标所在的位置，所以很奇怪......

只要将item从droppable区域移出，它就需要飞回draggable并整齐的显示在draggable区域（item list位置）。 但似乎一直锁定/不能整齐地飞回来
