Unique secondary meny for certain post

Hello, you would have to install an extra plugin for this. My personal recommendation is this plugin: https://wordpress.org/plugins/polylang/

Note, however, that your website will slow down. You need a caching layer. Polylang is likely translating on every page load.

Hi there,

For different secondary menu on certain posts, this plugin might help:
https://wordpress.org/plugins/conditional-menus/

Also caching is definitely not required. We aren't using one on this site :)

Thanks! This works for the secondary menu on desktop, unfortunately not for the slide-out menu so far!
