Does Google Map support <BalloonStyle><text> like Google Earth?

Question

I am uploading kmls into Google Map (not Google Earth).

My KMLs contain polygons (county borders).

There is a different "styleurl" for each county. Right now I can control the content of the bubble via <name> and <description> from within the polygon's <Placemark> tags. Instead I would like to control the bubble content from within the Style definition, using

<BalloonStyle>
<text>My custom text</text>
</BalloonStyle>

Q1 Does Google map support these functions (my testing so far suggests "no")

Q2 Where could I have looked up this answer on my own before posting here?

Thanks!

Answer 1

Per the documentation <BaloonStyle> is partially supported by the API:

<BalloonStyle> partially only <text> is supported
