[Zope] newbie tree q - how collapse and expand

[Chris Withers]

expand_all and collapse_all are all very well but I think Andy is after the same
thing that I gave up on. 

How can you expand or collapse a tree to a specific point, ie:

- make a particular subtree expanded 

- make sure a particular node in the tree in visible

The Zope DTML guide mentions the tree-s, tree-e and tree-c variables but it
doesn't explain how to use them. I haven't found any help anywhere on this.

Any ideas?
