[Patrick]

The following KML render polygons from two groups.
The larger polygon and small polygon should render on top of the green
midsize one.
This example show that small one is rendering under the midsize one.

Hi Patrick,

KML doesn't have any way directly to indicate z-order for a Polygon.
However, you can simply put it at a higher altitude, say 1 meter, and
that should work. It worked for me.

You might want to see this thread for a workaround. Good luck.
