I want to hide the shadow from infowindow in Google Map API V3. I am trying to access the Floatshadow panel, but I do not know how to do this.
Try something like the InfoBubble library. This cannot be done in the API itself.

edit: Starting from version v3.11, info windows do not have shadows by default.
<style type="text/css"> img[src*="iws3.png"] { display: none; } </style>
.
infoWindow
google.maps.event.addListener(InfoWindow, "domready", function() { setTimeout(function(){$("img[src$='iws3.png']").hide();},80); });
