Hi Marc,
thanks a lot for the tips. Just checked it out, but unfortunately I get a "TypeError: Result of expression 'this.map' [null] is not an object." in "OpenLayers.js:803" on the "sm: ....." line. Any idea what that can mean or what to do about it?
Cheers,
Stefan

And that is some kind of mouse-over effect. When a user is moving the mouse over some polygons, would it be possible to highlight the attributes in a grid at the side? Or display a small box next to the cursor?
