Most people are likely to use some lines of PHP or the widget provided by the <a href="https://wordpress.org/plugins/multisite-language-switcher/" rel="ugc">Multisite Language Switcher</a> to integrate the links to the translations in their blogs.
But this can lead to fatal errors if you don’t know much about PHP, or maybe the dynamic sidebars are not the best place in your opinion. If you want to integrate the Multisite Language Switcher in one (or more) of your Navigation Menu(s) then you should give MslsMenu a try.

Are you welcoming visitors from different countries on your site and don’t know how to serve all of them the best possible reading experience? Then just give Lingo a spin and you won’t regret it.
A the best of it: You don’t need to even think about accomplishing this, the plugin does all of that work for you. The only thing you need to do is provide a translated version of each post you would like to show in multiple languages and there you go: Everything works right out of the box. There’s no need for configuring – it just works.
<h4>Functionality</h4>
The plugin provides you with a clean, simple workflow on how to create translations. After you’ve chosen a specific post which you want to translate, you just need to click ‘Translate’ on the post overview. Then Lingo will create a complete copy of the post and assign it a special post type so that it’s completely isolated from normal posts.
After that, you’ll see an edit screen that looks nearly exactly like the one for your original post. You can use the WYSIWYG-Editor, all types of metaboxes and so on. After providing a translation you just need to pick the suitable language and hit ‘Save’.

<h4>Supported Languages</h4>
Lingo currently makes use of all languages that are available on the ‘Site Language’ select-field in the admin area of your site (‘Settings’ > ‘General’ > ‘Site Language’ ). But don’t get me wrong: It doesn’t matter how many languages are installed on your site, Lingo works with all of them anyway.
