How to call controller from view without form submission ?

What you really need is a model to load in your view so your menu can read the submenu items.
To do this you could just pull in the instance of CI, then call your model, then call the subquery:

PHP Code:

$this->_ci = &get_instance();
$this->_ci->load->model('Menu_model');

// inside your loop
$this->_ci->Menu_model->get_submenu($row->top_menu_id); 


Obviously, using your own model name, column names and function calls (since I didn't know them, I made mine up)
