[Cartoweb-users] LayerGroup rendering

[Alexandre Fellay]

Hi Dejan,
You can't fold/unfold direct children of a block-rendered layergroup. 
The work-around I suggest is to insert an intermediate level like

layers.root.children = layergroup1_up, layergroup2_up
layers.root.rendering = block
...
layers.layergroup1_up.children = layergroup1  ; intermediate level, 1 
child only
layers.layergroup1_up.rendering = tree
...
layers.layergroup1.children = layer1, layer2  ; that's the "real" 
layergroup"
layers.layergroup1.rendering = tree

If you don't want the label (of layergroup1_up)  to appear in the 
block's frame, you'll have to slightly modify the template layers.tpl
