[OpenLayers-Users] TURN On layers Individually...

[Paul james]

I´m trying to do something like that :
http://demo.mapfish.org/mapfishsample/1.1/examples/tree/tree_automatic.html

There is a layer :

c2cwmsLayers = ['parkings', 'summits', 'refuges', 'sites'];
    c2cwms = new OpenLayers.Layer.WMS("C2C Objects",
        "http://demo.mapfish.org/mapfishsample/1.1/wms?",
        {
            singleTile: true,
            layers: c2cwmsLayers,
            format: 'image/png',
            transparent: true
        }
    );

But using the treeview I can turn on/off : 'parkings', 'summits', 'refuges',
'sites' Individually...

Paul
