[Zope] newbie tree q - how collapse and expand

[Andy Heath]

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Andy
