[Vuejs]-Vue – How to display the clicked item and the previous/next item of an array

You can indeed create 2 components. 1 component having a list of all the stations. another component displaying the details of the radio station.
The moment you click a station in the list, it sends an event and updates a property in the vue.app. This could for example be called selectedStation.
your component that shows the detail of the radiostation just receives a prop with the details of the station.
