Update info on same screen when clicking maps markers?

I know it’s possible to link to a new screen, but can you update info on same screen?

I’m creating an app for a food guide & would be very useful - please see attached screenshot.

What info are you wanting to update on that screen and how?

The custom list beneath the app is a lift of restaurants. I would like it to display restaurant information that is clicked on the map, rather than just display all restaurants.
