private function select($modules, $level = 0)
{
    $return_html = '';
    $level_html = '';
    $new_level = 0;
    
    foreach($modules as $module)
    {
        $repeat = str_repeat('     ', $level);
        
        if(!empty($module['children']))
        {
            $return_html .= ''.$repeat.' '.$module['title'].'';
            
            $new_level = $level+1;
            
            $return_html .= $this->select($module['children'], $new_level);
        }
        else
        {
            
            $return_html .= ''.$repeat.' '.$module['title'].'';
        }
    }
    
    return $return_html;
}
