Creating a bullet list view for the Tree tutorial

I've been at this for a while and I'm completely new to Cake PHP and full
stack web frameworks period.
I simply want to turn the tree data in the Tree tutorial here
<http://book.cakephp.org/2.0/en/core-libraries/behaviors/tree.html> into a
nice HTML bullet list for learning purposes.

*I have the model*

<?php
class Category extends AppModel {
public $actsAs = array('Tree');
}

?>


*I have the controller*


<?php

class CategoriesController extends AppController {

public function index() {
$data = $this->Category->generateTreeList(null, null, null,
'&nbsp;&nbsp;&nbsp;');

}
}

?>




The view is whats missing.
I tried playing with the set method and adding it to the index action in the
CategoriesController hence assigning it a usable variable in the view.
Nothing seemed to work.

I'm hoping someone could direct me on the right track.

Thank you.
