Create a reservations popup only with the top section (displaying details of the selected item)

When the popup loads, the webapp retrieves data from the selected API and shows details about the selected item.

Add event to button prepared by your teammate that will open your popup. You need to communicate with your team member to make sure that you do not block each other (most likely the easiest solution is to merge the list of items feature to the dev branch before you try to add that event).
