Swift Menu Duplicator

Swift Menu Duplicator

Description

Swift Menu Duplicator gives you full control over your WordPress navigation menus. Clone any menu in one click, manage all menus from a dedicated admin page, version them with snapshots, move them across Multisite sub-sites, and automate everything from the command line or REST API.

One-Click Duplication

  • Duplicate button right in the menu editor footer — no page reload required
  • Full hierarchy preserved via a two-pass clone that remaps all parent-child item IDs
  • All item metadata copied — type, object, URL, target, CSS classes, XFN, description
  • Duplicate individual menu items directly from the menu editor
  • Custom name support — filter swift_menu_duplicator_new_menu_name to override the default “(Copy)” suffix

Snapshot Revisions

  • Auto-snapshot — a snapshot is saved automatically before every menu save
  • Manual snapshots — save named snapshots from the menu editor at any time
  • Browse & restore — view all snapshots in an expandable panel and restore with one click
  • Housekeeping — delete individual snapshots you no longer need

Menu Manager (Appearance Menu Manager)

  • Dedicated page listing every menu on the site in a sortable WP_List_Table
  • Bulk duplicate — clone multiple menus at once
  • Bulk export — download selected menus as a single ZIP archive
  • Bulk delete — remove multiple menus in one action
  • Row actions — duplicate or export individual menus directly from the list

JSON Export / Import

  • Export any menu to a portable JSON file (via admin or REST API)
  • Import from a JSON file upload or paste JSON directly into the text area
  • URL find & replace — swap domain names during import for staging production migrations
  • Dry-run preview — review what will be imported before making any changes to the database

Multisite Support

  • Copy any menu to another site in your WordPress Multisite network
  • Automatic URL rewriting in item URLs when copying across sub-sites

REST API

Full REST API at /wp-json/cmd/v1/ for headless and block-editor integrations:

  • POST /menus/{id}/duplicate — duplicate a menu (optional name parameter)
  • GET /menus/{id}/export — export a menu as a JSON payload
  • POST /menus/{id}/items/{item_id}/duplicate — duplicate a single menu item

Permission is controlled by the swmd_rest_permission filter (defaults to edit_theme_options).

WP-CLI

Full command-line support under the wp swift-menu-duplicator command group:

  • wp swift-menu-duplicator duplicate <menu-id> [--name=<name>] — duplicate a menu
  • wp swift-menu-duplicator export <menu-id> [--output=<file>] — export to JSON
  • wp swift-menu-duplicator import <file> [--name=<name>] [--find=<str>] [--replace=<str>] [--dry-run] [--porcelain] — import from JSON
  • wp swift-menu-duplicator copy-to-site <menu-id> --target-blog=<id> [--name=<name>] [--find=<str>] [--replace=<str>] — copy to a sub-site

Multilingual Compatibility

  • WPML — translation meta keys (_icl_lang_duplicate_of, wpml_language, etc.) are stripped from duplicated items automatically
  • Polylang — language meta keys (_pll_synced_taxonomies, _pll_menu_language, etc.) are stripped from duplicated items automatically
  • Additional keys can be excluded via the swmd_compat_excluded_meta_keys filter

Developer Hooks

  • swift_menu_duplicator_new_menu_name — customise the default duplicate name
  • swmd_rest_permission — control REST API access
  • swmd_before_duplicate_item / swmd_after_duplicate_menu_item — fired around item duplication
  • swmd_after_import_menu — fired after a successful import
  • swmd_item_meta_keys — control which meta keys are copied
  • swmd_compat_excluded_meta_keys — extend the multilingual meta exclusion list
  • wp_update_nav_menu — triggers auto-snapshot before every menu save

Security

  • All AJAX actions verified with nonces and edit_theme_options capability checks
  • All output escaped; all input sanitized
  • Database queries use $wpdb->prepare() — no string concatenation
  • REST API permission is filterable but defaults to edit_theme_options
  • WordPress Filesystem API used for all file read/write/delete operations

Requirements

  • WordPress 6.0 or higher
  • PHP 7.4 or higher
  • User with edit_theme_options capability

Screenshots

  • Duplicate Menu button in the menu editor footer.
  • Menu Manager page — sortable list of all menus with bulk actions.
  • Snapshot panel in the menu editor — browse, restore, and delete revisions.
  • JSON import form with URL find & replace and dry-run preview.
  • WP-CLI duplicate and export commands in a terminal.

FAQ

Does it copy theme location assignments?

No. Theme location assignments are site-specific and intentionally not copied, so the duplicate does not silently replace an active menu in any location.

What happens to sub-menu items?

All parent-child relationships are preserved exactly. The plugin uses a two-pass approach: items are cloned first, then parent ID references are re-mapped to the newly created item IDs.

Can I rename the duplicate before it is created?

Yes. A name field is shown in the duplicate modal. You can also change the default suffix globally by filtering swift_menu_duplicator_new_menu_name.

Is it compatible with WPML or Polylang?

Yes. Translation and language meta keys are automatically stripped from duplicated items so the copy starts as a clean, language-neutral menu.

Is it compatible with WooCommerce / HPOS?

Yes. The plugin only interacts with nav_menu_item posts and the nav_menu taxonomy. It has no dependency on WooCommerce or its High-Performance Order Storage.

Can I duplicate a menu that contains draft items?

Yes. All items are duplicated regardless of their post status.

How do I use the REST API?

Authenticate with a cookie session or an Application Password, then send:

POST /wp-json/cmd/v1/menus/{menu_id}/duplicate

The response includes the new menu’s id, name, and edit_url.

How do I migrate menus between environments?

Export the source menu to JSON (admin UI or wp swift-menu-duplicator export), transfer the file, then import it on the target site. Use the find/replace fields to rewrite domain-specific URLs during import.

What capability is required?

edit_theme_options for all duplication, snapshot, export, and import actions. Multisite copy-to-site additionally requires manage_options on the target sub-site.
