This's a (really simple) CI Core widget solution. Less elegant (?), but it's the same, i think.
Code: ## Lib
class Widget
{
function __construct()
{
$this->ci = & get_instance();
log_message('debug', 'Widget Library: Initialized');
}
function login()
{
//do_something
return $this->ci->load->view('widget/login_view', $data, TRUE);
}
}
## Controller
class Home extends Controller {
function index()
{
$data->login_box = $this->widget->login();// example to view etc...
$this->load->view('home/index_view', $data);
}
}
## View
<div id="login_box"><?php echo $login_box ?></div>
## Or just in view (for brave men)
<div id="login_box"><?php echo $this->widget->login(); ?></div>

@Dewos, Your widget class cannot possibly work as is. It has no reference to the loader so $this->load->view() will fail.
And besides simply building wrappers for other classes is a pointless waste of time and effort. You may as well have loaded the partial view in the controller.
Code: class Home extends Controller {
function index()
{
$data->login_box = $this->load->view('widget/login_view', $data, TRUE);
$this->load->view('home/index_view', $data);
}
}
Maybe you don't understand that the purpose of a widget is to relieve the controller from building page parts that are unrelated to it.

Hi wiredesignz. get_instance() added, but in regard it's only a schematic conceptual mock-up 
By the way, if you use in view <?=$this->widget->something()?> the controller is no-way implicated. It's the same of <?php widget::run('login'); ?>, or not?
P.s.
Thanks for Modular Separation, it's a really nice library.

The moment you use `$this` you are operating in the scope of the current object. In a view `$this` is actually the loader object so your $widget is a class variable of the loader via the controller. Thus the controller is definitely implicated. You will also need to create different libraries for every widget you need, using your approach you would need to repeat common code in every widget.
Notice that my Widget uses a static call to run, it is not attached to any object in CodeIgniter.

thanks for this plugin, wiredesignz, i have used the original one on page1 with PyroCMS and have to say that it was very simple and easy to set up and then create my widgets.
