Is it possible to expand disabled nodes. I have the following scenario:
- parent 1 (enabled and selectable)
+ child 1.1 (disabled and not selectable)
+ child 1.1.1 (enabled and selectable)
So I need a treeview where i can select different nodes individually. Right now when i disable a node i cannot access any child nodes.

Hi Frank,
A disabled node can be expanded programmatically through the TreeView's expand method. Here's a dojo example, which demonstrates the use of this method by expanding the "Nissan" disabled node.

Hi Ivan,
thanks for answering my question. But i'm afraid that is not really what i was looking for. I need the ability to expand and collapse disabled nodes by mouse klick in the tree (just like enabled nodes).

Hi Frank,
This behavior is not available out-of-the-box but here's a dojo example that shows how to achieve it through jQuery and the TreeView's methods.
