title: Select Multiple Polygons on Map in Xamarin Forms (Android and iOS)
body: <p>I have a Xamarin forms application that displays a map with multiple polygons on it.</p>
  
  <p>Is there a way for a user to tap and drag to create a square on the map, and that will select all the polygons in that area?</p>
  
  <p>Currently I use custom renders to create the polygons using Google Maps API2 for android and MapKit for iOS</p>
  
  <p>Thanks,</p>
