Hello all,  
I need a good technique to create a tree menu based off pages in a  
database with RoR. So, pages would look something like this in the db:

pages (  
id  
parent\_id  
title  
content  
)

Obviously, the parent\_id would be 0 or null for the top-level pages  
and any sub-pages would have the id under parent\_id. What I’m looking  
for as far as a read-out is a simple unordered-list with sub-lists  
under the parent’s list item… so:

- Parent 
  - Child 1
  - Child 2

If I can have it be recursive that would also be great.

Thanks

Have a look into acts\_as\_tree.
