只将一个元素放在前面的droppable中 [英] dropping an element only into the droppable that is in front

问题描述

我有一些可拖放区域，也是可拖动的。可能发生的是，两个或更多个可放置区域将彼此相背。有没有办法将可拖动项目只放到前面的区域？ （z-index）

I have some droppable areas, which are also draggable. It can happen that two or more droppable areas will get behind each other. Is there a way to drop a draggable item only into the area that is in the front? (z-index)

现在情况是，项目被添加到所有重叠的区域。

The situation is now, that the item gets added to all the areas, that are overlapping.

谢谢
