Rails - Feb 2010 - how to show a hierarchical list (like Mac Finder/Explorer)

I have a list of Groups with members and sub-groups in an unlimited
depth.

It has the same basic structure as a directory listing in either Mac
Finder or Windoze Explorer where the files a roughly analogous to my
members, and the sub-dirs are analogous to my sub-groups.  Just as in
Mac Finder, I would like to have it remember the "open-ness" of the
dirs/sub-dirs in the db so user will see it the same way on subsequent
uses of the app.

Is there some sort of a plugin for displaying this kind of a data set in
Rails?

If not, how would you go about designing this?  I''m stuck.

thanks,
jp

Thanks Robert.  This looks very interesting.  I''m php-challenged, so I 
will have to study it to figure out how to adapt it to Rails.  I don''t 
suppose you''ve  done that before?  Have any Rails demo code?

At a minimum, the notion of using <ul> and some fancy css gives me a 
start.

thanks,
jp

Why are you stuck?  2 minutes of Google searching on implementing 
hierarchical trees in SQL would have led you to the nested-set pattern. 
Another minute would have led you to the awesome_nested_set plugin for 
Rails.

Ok, I''m a moron.  I didn''t remember ever seeing one.  I came
here and
searched this group for "hierarchical".  Got bupkis.  Thanks much for 
making me aware of this new thing called Google.  Looks very useful. 
;)

cheers,
jp
