Как создать карту и зафиксировать div рядом с ней, чтобы содержимое div перемещалось с прокруткой?

var locations = [
  ['Bondi Beach', -33.890542, 151.274856, 4],
  ['Coogee Beach', -33.923036, 151.259052, 5],
  ['Cronulla Beach', -34.028249, 151.157507, 3],

  ['Maroubra Beach', -33.950198, 151.259302, 1]
];

var map = new google.maps.Map(document.getElementById('searchMap'), {
  zoom: 10,
  center: new google.maps.LatLng(-33.92, 151.25),
  mapTypeId: google.maps.MapTypeId.ROADMAP
});

var infowindow = new google.maps.InfoWindow();

var marker, i;

for (i = 0; i < locations.length; i++) {
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}

.searchContainer {
  overflow: hidden;
  position: relative;
}
