Swift Menu Duplicator

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
