Could you show your effort so far?
You probably chose one of the most difficult projects to decompile… They don’t use any plug-ins, in the classic CMS sense. If you want to explore this particular section you should take a look at it
That is made using React-Spring its a great animation library with physics too. Since the scene you want to create only have 2D elements on which the animation is to be applied it makes the work pretty easy.
Also the movement you see after the objects drop down is because of physics collision, each item is continuously colliding with each other making the objects to act like that.
Its basically up to you which approach you wanna take, if I were you I would have used React-Spring because the objects also react with mouse hover and thats pretty much what Spring does
