How to display indoor floors with Google Maps API (web)
<p>I need to display the indoor floors of a shopping center (already mapped and visible on maps.google.com) but after implementing a basic Google Maps JavaScript API those indoor floors do not show up in the map (just the first one).
Can the Javascript API show the different floors? and if yes, how can I implement it?</p>

<p>I implemented a "Base Map" from <a href="https://developers.google.com/maps/documentation/javascript/?hl=vi" rel="nofollow">https://developers.google.com/maps/documentation/javascript/?hl=vi</a></p>
