How do you allow users to create own menus? The idea is that a user should be able to create a menu to structure his uploaded content. How would you go about making this possible without giving the user access to edit other users menus?

Cheers,
Menu Admin Per Menu Module comes to solve this purpose!!


  The Drupal 7 Menu Admin Per Menu module is a simple module that allows
  you to grant permissions for users to administer specific Drupal menus
  based on their role. 
  
  This module for instance would allow you to allow one role to modify
  the Main menu, while not allowing the role to modify a separate menu
  on your Drupal 7 website.
