Hello list,


I'm new on GeoExt, and I'm trying to create a custom layers tree menu grouping baselayers and overlays layers in diferent folders.


I tryed with this code:


var treeConfig = [{

                                nodeType: "gx_baselayercontainer"

}, {

                               nodeType: "gx_overlaylayercontainer",

expanded: true




Inside Ext.Viewport:



items: [{

                                    title: 'Capes',

                                    xtype: "treepanel",

                                    loader: new Ext.tree.TreeLoader({

                                    applyLoader: false


                                    root: {

                                        nodeType: "gx_layercontainer",

                                      children: Ext.decode(treeConfig)





It doesn't work.


Any idea or example would be appreciate.


Thank's a lot.
