testing ruby: 1.9.3, 2.0.0; ancestry: 2.0.0

ancestry-treeview is an extension of ancestry gem to show a tree view which looks like http://jsfiddle.net/Fh47n/.

gem install ancestry-treeview

Add the following code in your app/assets/stylesheets/application.css.scss

@import "ancestry-treeview";

Then, call

node.tree

in your view where node is your ancestry model.

Default html links in the tree view are as

<a href="#">id</a>

You can change the html link by giving a block as

node.tree {|node| link_to("text", your_controller_path(node)) }

As default, all childrens of a node is shown as a tree. Use to_depth option to contraint the depth

node.tree(to_depth: 1)

I appreciate Vitaliy Bychik for giving such a nice css style at http://stackoverflow.com/questions/11167628/trees-in-twitter-bootstrap .
