Allows users in a WordPress multisite network pull in menus from a main site in order to achieve universal navigation or shared navigation without needing to manually recreate menus.
Plugin is intended for WordPress Multisite environment for plugin to function properly and use the same theme to ensure menu name compatibility.

Multisite Shared Menu

Breaks admin bar on any site this plugin is active on. The admin bar will act like you are on the site that this plugin is getting the shared menus from. 
I'll change my rating if this bug is fixed.



Breaks admin bar.

Works perfectly. Just as described. Saved us a ton of time! Thank you!

Perfect, just what we needed!

Use navigation menus from another multisite blog on the same network to achieve a universal common navigation area.

This plugin extends the <a href="https://wordpress.org/plugins/json-rest-api/" rel="ugc">WordPress JSON REST API</a> with new routes for WordPress registered menus
The new routes available will be:
<ul>
<li><code>/menus</code> list of every registered menu.</li>
<li><code>/menus/<id></code> data for a specific menu.</li>
<li><code>/menu-locations</code> list of all registered theme locations.</li>
<li><code>/menu-locations/<location></code> data for menu in specified menu in theme location.</li>
</ul>
Currently, the <code>menu-locations/<location></code> route for individual menus will return a tree with full menu hierarchy, with correct menu item order and listing children for each menu item. The <code>menus/<id></code> route will output menu details and a flat array of menu items. Item order or if each item has a parent will be indicated in each item attributes, but this route won’t output items as a tree.
You can alter the data arrangement of each individual menu items and children using the filter hook <code>json_menus_format_menu_item</code>.
An important note on WP API V2:
In V1 the routes are located by default at <code>wp-json/menus/</code> etc.
In V2 the routes by default are at <code>wp-json/wp-api-menus/v2/</code> (e.g. <code>wp-json/wp-api-menus/v2/menus/</code>, etc.) since V2 encourages prefixing and version namespacing.
