react-spring

问题 I'm trying to get my head over React Spring. So I have some boxes, which I need to filter by an active index, and the idea is to animate the boxes rendering, but I'm only having an animation when the component renders the first time.

问题 I have a list of labels that I render with a React-Spring Transition. The idea is that you can add items and if you have more than 5, a "Show more" button will appear.

I noticed that before my items were hidden, all of them but the first moved to the beggining of the list, generating a weird effect where you can see the first labels
