Making Google map marker mouse-over more interactive

I have a map with a google marker, but I would like to do some fun things with it like post a link in there, and format the text there to have an information item per line instead of all in one line.

Is tha开发者_如何学运维t possible? If so, then what can be done and how? :) Here is my current boring map and marker at the bottom of this page: http://www.comehike.com/outdoors/parks/trailhead.php

You could do:

<script...

var marker = new GMarker(point);
map.addOverlay(marker);
var myHtml = "<your html here/>";
GEvent.addListener(marker, 'mouseover', function() {
     map.openInfoWindow(point, myHtml); 
};
.../>

where

<your html here/>

is what you want to show, for example image and contact info or something. That is if you want the info window opened on mouseover event. You could either open it by default by calling that function ( map.openInfoWindow(point, myHtml) ) right away.

Hope that helps.
