What I am trying to do is to list a menu. At the Top will be parent menu and below the child menu.
Now if I am not mistaken when the key name of the array is childs it will do the iteration for all the variables inside the {childs}{/childs} but what about the parents that they have key names 0,1,2? Can I do something to change them so I can do the {top_titles}{/top_titles} iteration?

I want to parse a multi-dimensional array using the parser class like this:

Code:
{top_titles}

    <li><a href="&lt;?=base_url()?&gt;index.php/{link}">{title}</a>

        <ul>

        {childs}

        <li><a href="&lt;?=base_url()?&gt;index.php/{link}">{title}</a></li>

        {/childs}

        </ul>

    </li>

{/top_titles}

The Controller looks like this:

Code:
&lt;?php

class Home extends Controller {

    function  _get_child_array($iStart)

    {

        // Init

        $aCategories = array();

        // Call database

        $aCategorieOverview = $this->Header->get_overview($iStart);

        return $aCategorieOverview;

    }

    function  _get_category_array($iStart)

    {

        // Init

        $aCategories = array();

        // Call database

        $aCategorieOverview = $this->Header->get_overview($iStart);

        // For all categories found

        foreach ( $aCategorieOverview as $sKey=>$sValue ) {

            // create new category item and fill it up

            $aCategory                   = array();

            $aCategory['id']        = $aCategorieOverview[$sKey]->id;

            $aCategory['title']        = $aCategorieOverview[$sKey]->title;

            // Get childs if there are any (recusive) and add them to this level

            $aChildCategories         = Home::_get_child_array($aCategory['id']);

            if ( !empty($aChildCategories) ) {

                $aCategory['childs'] = $aChildCategories;

            }

            // Add category to the categories array

            $aCategories[] = $aCategory;

        }

        // Return the results

        return $aCategories;

    }

    function index()

    {

        $this->load->model('Header');

        $array = $this->_get_category_array(-1);        

        $this->parser->parse('admin/header.tpl', $array);

    } 

}

The Model looks like this:

Code:
&lt;?php

class Header extends Model {

    function Header()

    {

        // Call the Model constructor

        parent::Model();

    }

function get_overview($iStart)

    {

        $this->load->database();

        $query = $this->db->get_where('my_admin_cp_menu', array('pid' => $iStart));

        return $query->result();

    } 

}

?&gt;

If I try to print the array and see what is inside them I get the following result:
