Checking or unchecking the checkbox of this node will directly affect all layers and vice versa. The default iconCls for this node’s icon is “gx-tree-layer-icon”, unless it has children.
All methods will delegate to the superclass GeoExt.tree.LayerNode.
To use this node type in a TreePanel config, set nodeType to “hr_multilayer”.
