my own helper creating menu

[eluser]Krystian[/eluser]
Thank you for you reply InsiteFX. This is my 2nd project in CI.
Two more questions:

1. I autoload create_menu in config file and when in controller

Code:

$data['menu'] = create_menu(0, 1);

I get
Fatal error: Using $this when not in object

2. Is it good convention/idea to code all my old ( I pasted it somewhere above ) function into helper? with html tags etc...

3. And more important now is that I don`t know how to use recursive helper

can you please give me example pseudo code how to do this?
