For example, this picture shows how the collection View should look like.
I want the First View to show an array of around 6 items in collection view. 2nd View to show an array of objects that relate to the object you click in first view. Which are 50+ objects depending on which object was clicked. For 3rd View is going to be a pop up view of detailed info for the object you clicked in 2nd View.
I know how to fill a collection view but not how to create what I want. Just want a collection view like in the picture, thanks!
