No problem, you can have the code that builds the infowindow only display tabs if there's something to go in them. If you're going to have any function like show/hide markers by category, you could test the same data to see if each marker falls into that category (as well as any others). A tricky part might be poulating the markers initially - i.e. when adding the second category from a new dataset you will need a test "does this location already exist?" and only create a marker if not. You could probably use something like an internal site reference number rather than any fancy geo-methods. cheers, Ross K --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
