How to create seperate animation for collection list items

I’d like to have a list of pictures from a collection list. Every picture represents a person and has a description linked to them. If I click on the most left picture I’d like that person’s description to appear below the pictures and all the other descriptions from the other people may not be visible and the picture should be blurred slightly.

I can only add animations to all the collection list items but not separately.
What I want it to look like is like on the following webpage:
