How to implement the fall of the elements when removing the element(s)?

Question

Animation

How can I implement something like in the picture, that is, so that the elements fall smoothly if some element is removed? Unfortunately, the option to decrease the height of the element being removed results in a non-smooth animation (that is, it doesn't look like a free fall like in reality) if several elements are removed at the same time.

May I ask for an example please - which approach should I choose to implement?
