Is it possible for an InfoWindow to popup over an element which has a higher Z-Index than the google map?
So lets say the google map has a z-index of Zero. The element has a z-index of 100. Clicking a marker displays an InfoWindow in the same region as the element. How do we get this InfoWindow to hover over the element and not under it?
I have tried setting the InfoWindow's z-Index to a higher value, but this does not appear to do anything.
I've put together a demo below demonstrating the issue. Any assistance would be appreciated!

You can use a custom control instead of outer element to place on the map. The custom control is placed above the map and when you open an InfoWindow, Google maps detects the position of the control and automatically moves and opens the InfoWindow below the control, so the both don't overlap. In this case it is better to use it instead of the custom overlay, because the overlay moves when you drag or zoom the map and the control always stays at the same position.
So, first you have to add the map and the control as div-s in your html, then to initialize the map and after that to add the control to the map like that:
var control = document.getElementById('control');
map.controls[google.maps.ControlPosition.TOP_LEFT].push(control);
How simple is that ;)
