Add custom fields to drupal navigation menu without breaking the version

Question

Is it possible to add custom fields to drupal navigation menu (besides title and description)?
I want to keep the version without breaking it.

Answer 1

There's a module for that. Menu attributes: http://drupal.org/project/menu_attributes .This module specify some additional attributes for menu items

If you need a more complex solution, you can reuse the code of menu attributes and write your custom fields.
