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);

Even tho this will work ist not a good pratice to get the data in the view file. Strictly speaking the view creates the html and should have all the data needed to do this.
I would get the data in the controller and pass it to the view. In the controller you very liklely have already loaded the model so why would you load it again in the view.
But this is just my personal preference.

Since this is a menu (from what I gather), if I were to put it in the controller (which I agree is where it belongs, strictly speaking) - I would create a MY_Controller, put it there and then have all of the other controllers inherit it. This way, the menu system isn't being put everywhere and you've got one isolated location for it.
The code to create all of the data (as I'm assuming dynamic menus that change here) is also a little annoying to do without incorporating some view stuff in the controller, you have to create the loop, then get the view for the menu and its sub items, then merge them all, then pass to the final view. Seemed like a lot of extra work for the exact same result with no real life benefit, which is why I recommended what I did.

Obviously, using your own model name, column names and function calls (since I didn't know them, I made mine up)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);
Hi Kaosweaver,
Thanks for your reply with code it helps. Is there any way to do like i have my leftsidebar_contolle,leftsidebar _model and leftsidebar _view so i can load them once and use in application. like other controller,model,views we use.

I think Ajax can be a good option though.

Whatever you're doing, you're doing it wrong.
