CSS transition in React

So, I have this test project where I need to make so that when I deleted the one of the data it will have some animation/transition. It actually worked fine. But, the problem is I want it so that, the element or the data below the data I deleted, to have a slide up animation like this http://jsfiddle.net/kMxqj/17/

How to make it in react and without jquery? That is my question.

I actually already tried to make it but this is what I got https://codesandbox.io/s/3qk6j2mwvm

I can’t make the slide up animation. Please help me if you know how to do it.


Edited: I already solved this. Now the problem is, how to delete this post?
