README

Replace the default My Sites menu in the WordPress Admin Bar with a fast, searchable All Sites menu — built for super admins managing large multisite networks.

Why?

The built-in My Sites menu has problems on large networks:

• It only lists sites where you are a local admin.
• It can't scroll past the viewport (open bug since 2010).
• It calls switch_to_blog() for every site, which is slow.

This plugin fixes all three. Site data is fetched once via the REST API, cached in IndexedDB, and rendered client-side — so the menu loads instantly on subsequent visits.

Features

• Switch free, no switch_to_blog() — reads site properties directly, avoiding the performance hit.
• IndexedDB caching — menu data is stored locally and updated automatically when sites, blog names, or monitored plugins change.
• Incremental REST loading — fetches sites in batches (default 100) so the admin bar isn't blocked.
• Lists every subsite, not just sites you administer locally.
• Alphabetical sorting with a built-in search filter (appears when you have 20+ sites).
• Restricted Site Access indicator — sites running Restricted Site Access get a red icon.
• Extra quick-links per site: New Page, Users, Plugins, Settings; plus "Add New Site" under Network Admin.

Requirements

Installation

WordPress.org

Install from wordpress.org/plugins/super-admin-all-sites-menu, then Network Activate.

Manual

1. Download the latest release.
2. Upload to wp-content/plugins/ and network activate.

Composer

composer require soderlind/super-admin-all-sites-menu

Filters

All filters are optional. Add them to a plugin or your theme's functions.php.

all_sites_menu_order_by

Sort order. Accepts name (default), id, or url.

add_filter( 'all_sites_menu_order_by', function( string $order_by ): string {
    return 'url';
} );

all_sites_menu_load_increments

Sites fetched per REST batch. Default 100.

add_filter( 'all_sites_menu_load_increments', function( int $increments ): int {
    return 300;
} );

all_sites_menu_plugin_trigger

Plugins whose (de)activation triggers an IndexedDB refresh. Default: [ 'restricted-site-access/restricted_site_access.php' ].

add_filter( 'all_sites_menu_plugin_trigger', function( array $plugins ): array {
    return [
        'restricted-site-access/restricted_site_access.php',
        'myplugin/myplugin.php',
    ];
} );

all_sites_menu_search_threshold

Minimum number of sites before the search field appears. Default 20.

add_filter( 'all_sites_menu_search_threshold', function( int $threshold ): int {
    return 40;
} );

all_sites_menu_force_refresh_expiration

Seconds between forced cache refreshes. Default 3600 (1 hour). Set to 0 to disable.

add_filter( 'all_sites_menu_force_refresh_expiration', function( int $seconds ): int {
    return 7200;
} );

all_sites_menu_submenu_items

Customise the per-site submenu items. Add, remove, or reorder entries. Each item is an associative array with id, title, and href keys.

Parameters:

Add an "Edit Site" link (network admin):

add_filter( 'all_sites_menu_submenu_items', function( array $items, int $blog_id, string $admin_url ): array {
    $items[] = [
        'id'    => 'edit-site',
        'title' => 'Edit Site',
        'href'  => network_admin_url( 'site-info.php?id=' . $blog_id ),
    ];
    return $items;
}, 10, 3 );

Remove "Manage Comments":

add_filter( 'all_sites_menu_submenu_items', function( array $items ): array {
    return array_filter( $items, fn( $item ) => $item['id'] !== 'c' );
} );

Demo

Try it in WordPress Playground (loads 50 subsites — may take a moment).

• Deactivate the plugin to see the default My Sites menu fail to scroll.
• Activate Restricted Site Access to see the red indicator icon.

The PHP timestamp acts as a cache version. It is bumped whenever a site is added/deleted, a blog name changes, or a monitored plugin is (de)activated. On the client side, a mismatch triggers a full re-fetch; a match means the cached data is used as-is.
