how to communicate to a controller or model from view in laravel

I want to get menus from database which may also have sub menus. For all menus passed to views I want to check if they have sub menus or not and perform the action accordingly. If it was on codeigniter I could do like following:

    Controller:
       function test()
         {
        $qry=$this->db->get('menus');
        if($qry)
        {
            $this->data['menu_data']=$qry->result();
        }
        $this->laod->view('abc',$this->data);
      }

View abc

     <?php foreach($menu_data as $val) {?>
         <li><a href=""><?php echo $val->title; ?>
         <? php $submenu=$this->general->get_submenu($val->id); foreach($submenu as $smvalue {) ?>
           <ul>
             <li><?php echo $smvalue->title?></li>
           </ul>
           <?php } ?>
         <li>
         <?php } ?>

Say the general is a Library class and there get_submenus function lies. In Laravel how do I do it? I am very new to Laravel and just starting to practice.Any kind of help are appreciated. Thanks in advance.
