How to display Open atrium space titles like a menu tree?

Hi Everyone,

In Open atrium, we have created lot of spaces with hierarchy. For example, here is a visual representation.

  1. Parent Space 1
    1. Child space 1
    2. Child space 2
      1. Grand child space 1
      2. Grand child space 2 …

We want to display title of these spaces in a tree structure shown above and highlight corresponding space when user land on that page.

Can you please suggest how to do that?
