How to add additional blocks to the Navigation block

If you’re using a Full Site Editing (FSE) theme or the block editor, you can add the WPML language switcher using a shortcode within the Navigation block. WPML provides a shortcode for the language switcher, which you can embed directly into the block using the “Shortcode” block. This way, you can display the switcher in the navigation.

WPML can add the language switcher directly to the navigation menu for classic themes via the “Menu” options in the WP Admin under Appearance > Menus. Hopefully, this helps!

Let me know if you need more specific instructions based on your theme setup.

Hi @titopu

I just tried adding the Shortcode block directly to the Navigation. Dragging it through List view as well as adding the block directly to the Navigation.

The block was added above or below the Navigation and not into it.

Here is useful code to know about received from a core contributor/developer whom works on the Navigation. Hopefully various language plugins can look into this and make it possible to add a language switcher to the Navigation.

We’ve now opened it up
You can filter the block settings and add the block in question to the allowedBlocks property for the settings.
