I'm not asking about how to create a dropdown menu.
I'm asking instead of pasting the same code several times how can I manage to put it as the form of global variable.
I've tried to create a library but inside library I can't load the model so as to generate the result from database.

Not sure how you thought the suggestion of using a helper was explaining how to build a dropdown function...
However...
A helper is a standard way of reusing code that performs a repetitive task (because an helper is just a collection of related functions.)
Your example, however, is a perfect candidate for a model (especially since you are using the database class.)

Why do you need to call it from a helper function? Why not call it directly?
the answer is, of course, to get an instance of the CI super object.
Code:
function some_helper_func()
{
$CI =& get_instance();
$CI->load->model('your_model');
$CI->your_model->some_model_func();

I haven't actually given you any instructions. I have never seen your code. Thus, I have done nothing more that make suggestions. That being said...
This notice (not an error) is generated from what seems to be you trying to access db as a property of your model. Yes, since models extend the Model class, you can access the db object via $this->db INSIDE your model class. You cannot access via:
Code:
$this->your_model->db->count_all()Which I can only guess at because you haven't actually posted any code.
