menu->submenu out of database

[eluser]Bartolo![/eluser]
Hi guys!

this is my first post here and i want to let everybody know that codeigniter rocks! ...but you already knew that ;-)

okay...my problem:

i got a dropdown menu that comes out of the database, i got it working, but as you can see there is an function inside the view. thats off course not what i want.

is there anyone who can help me rebuild this so i have the functions on the place where they belong?

Code:

TABLE 'insurance_categorie'
- cat_id
- title
- info

Code:

TABLE 'insurance_item'
- insurance_id
- cat_id
- title
- link
- info

Model

Code:

function getMenuCategories() {
    $query = $this->db->get('insurance_categorie');
    if($query->num_rows() > 0){
        return $query->result_array();
    } else {
        show_error('Fout! Geen menu items opgehaald.');
    }  
}

function getMenuItems($cat){
    $this->db->select('*');
    $this->db->from('insurance_item');
    $this->db->where('cat_id', $cat);
    $query = $this->db->get();
    if($query->num_rows() > 0){
        return $query->result_array();
    } else {
        show_error('Fout! Geen menu items opgehaald.');
    }        
}

Controller

Code:

$data['menu_categories'] =  $this->Mainmodel->getMenuCategories();

View

Code:

foreach($menu_categories as $menu_categorie):
    echo "<li class=\"level1-li\"><a >" . $menu_categorie['title'] . "</a>";
    echo "<ul class=\"sub\">";
    foreach($this->Mainmodel->getMenuItems($menu_categorie['cat_id']) as $submenuitem):
        echo "<li><a >" . $submenuitem['title'] . "</a></li>";
    endforeach;
    echo "</ul>";
echo "</li>";
endforeach;
