[Solved] Expand nodes with 1 child

[Michael Prosper]

I have a treeview with multiple root nodes and levels that go about 7 deep.  Some of these nodes only have 1 child node for many levels of the tree.. for example:

Root
   child 1
      grandchild 1
         greatgrandchild1
         greatgrandchild2
         greatgrandchild3
   child 2
      grandchild1
         greatgrandchild1
         greatgrandchild2
         greatgrandchild3
      grandchild2
      grandchild3

The users of my tree have complained that they have to click three times to get access to the "greatgrandchild" nodes: once on "Root", once on "child", and once on "grandchild".

What i want to do is have all child nodes of the selected node automatically expand if they only have 1 child.  In the above example, if a user clicks on "child 1", then "grandchild1" automatically expands to show the greatgrandchildren.  That reduces the number of clicks it take to get to the deepest node.

However, if a user clicks on the "child 2" then the "grandchild" nodes do not expand automatically because there is more than 1 child.

Is there a way I can do this client side?

Thanks!
