How to create a CMS list that controls another

Hi there,

Im trying to solve the next challenge. If you have a look at the share link you can see at the bottom of the home page a list of several projects. I created two CMS lists. On the right the project list and on the left the selected project.

I would like that the left side is changing header and image when a certain project is selected from the right list.

Until now I have no luck getting them to communicate with each other.

Nobody with any idea on how to solve this? ((
