[Cartoweb-users] url parameter for dropdown

[wochter]

Hi,
I have defined dropdown...

layers.vyber_budov.className = LayerGroup
layers.vyber_budov.children = b1,b2
layers.vyber_budov.rendering = dropdown
layers.vyber_budov.label = Buildings

Now I need access layers in building b2 using url parameter and I don't
know how to do it.

http://localhost/cartoweb3/htdocs/swdemo.php?reset_session&
  switch_id=default&
  layer_select=layer1,layer2&   (I use layer1 or layer2)
  id_recenter_layer=layer1&
  id_recenter_ids=3

layer1 is in dropdown child b1 and layer2 in child b2

in case layer1 is everything ok but when I want to select layer2 is this
layer displayed but not checked in legend (bacause layer2 is in second
dropdown)

Is there any solution please?
thank you
