PlaceMark B

I cant select PlMark A beceause B is bigger, but when I have

PlaceMark B

Yes, because I think A is smaller and it was the last in be grapicated, my question is I cant have the Placemarks In order,there are any option in Kml to made selectable all the elements.

Thanks.

    If you want to order one line or polygon over another you can use the <gx:drawOrder> element.

    Features with higher <gx:drawOrder> values are drawn on top of those with lower values so for example if you use a drawOrder of 2 for A and 1 for B then A is drawn on top of B. In other words, the features with lower drawOrder values are drawn first.

    Don’t forget to add the xmlns:gx=”http://www.google.com/kml/ext/2.2″ declaration to the kml tag and note that the documentation says it only applies to LineStrings but it also applies to Polygons and LinearRings.
