Safely duplicate WordPress navigation menus from the menu editor.

== Description ==

CC Duplicate Menu adds a Duplicate Menu button to the WordPress menu editor, allowing you to create a full copy of an existing navigation menu.

The duplicated menu:

* uses the original menu name with “ (copy)” appended
* keeps the same links and labels
* preserves menu hierarchy and order
* creates new menu items so the copied menu can be edited independently

The plugin is built with security, privacy and WordPress coding standards in mind.

== Installation ==

1. Upload the plugin files to the `/wp-content/plugins/cc-duplicate-menu/` directory, or install the plugin through the WordPress plugins screen.
2. Activate the plugin through the ‘Plugins’ screen in WordPress.
3. Go to Appearance → Menus.
4. Edit an existing menu and use the Duplicate Menu button between Save Menu and Delete Menu.

== Frequently Asked Questions ==

= Does this alter my original menu? =

No. A new menu is created with new menu items, so the copied menu can be edited independently.

= Does it preserve nested menu items? =

Yes. The duplicated menu preserves hierarchy and order.

= Does it duplicate custom menu item metadata too? =

Yes. This version safely copies standard WordPress menu item fields and non-core menu item metadata, while excluding protected internal keys. Filters are included for developers and future extensions that need more control.

== Screenshots ==

1. Duplicate Menu button shown between the Save Menu and Delete Menu controls.
2. Success notice after duplicating a menu.
3. Newly duplicated menu opened in the editor.
