[Users] Tree Layer question...

[Paul james]

Hi Andreas...

In my case I need :
 - Possibility to create a custom treeview (like model in mapfish)
 - Supporting sublayer (Layer.Mapserver), like Mapfish does
 - Possibility to add a Radio button in some nodes (with Checkbox)
 - Possibility to takeoff all icons (mapfish stay with a ugly white space
when I dont use a icon)

Thanks

Paul
