This plugin makes it possible to have a menu that is controlled by the primary site but used throughout all other sites in the network.
<ul>
<li>When a navigation menu position has no menu assigned, the “fallback” defaults to pages. This plugin over-rides that so that instead it uses the nav menu from the “main site” (site ID 1)</li>
</ul>

Network Menu Fallback

Gives multisite administrators the ability to create menus that can be used throughout a network.

Multisite Language Switcher

Do I have to add anything else?

Made my life (a lot) easier!

It does exactly what it should

I have been using this plugin in combination with MslsMenu for more than 7 years now. 

For me this is a simple, yet absolutely perfect solution for any multilingual WordPress site. Very easy to use. Easily linking cross-blog pages together without having to worry about any third-party plugin compatibility. 

Its simplicity allows website admins full control over the content of each individual blog. Perfect if not all your blogs offer the exact same content, like country-restricted services such as gift cards or house calls or payment methods.

WordPress MultiSite handles all settings per blog and with MultiSite Language Switcher you can use different date/time formatting, even different email addresses, etc. tailored to the blog's locale. 

Thank you very much for providing the perfect solution, Dennis!

The prefect, simple solution!

A simple, powerful and easy-to-use plugin that will help you to manage multilingual content in a multisite WordPress installation.
