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.
