Add additional fields to menu settings

Hi all,

I just wanted to create an additional text field to WP nav menu in admin side (not to each nav menu items, but to a menu, like there is a default option with a check box says ‘Automatically add new top-level pages to this menu’). What I want is to set a title for each of my menus. I have around 6 different menus and I am using them for different pages of my website. I know, I could use the menu name itself as the title, but I don’t want to.

I got many examples to add meta boxes to the left hand side, but not to RHS.

Can anyone help me? thanks in advance.

Hakkim.
