Yes I guess that would do the trick.
If these meta tags are added to the post, then the post will show up in the website when any of these languages is selected, and without the website switching back to the default language (e.g. FR menus still displayed even tough the post is in English).

Again, the WPML docs mention a “translatable” attribute that lets you specify that a post will not be translated, resulting in the post showing up in the website no matter which language is selected. Haven’t tried it though…

+1 as well.
Same scenario as mentioned above : 2-language site, the homepage and general pages are available in both English and French, but I also have course / lesson / topic custom posts (from LearnDash plugin) that need only be available in EN. But if a FR user accesses one of the LMS posts (e.g. a lesson or topic) the site language automatically switches back to EN, which is not the desired behavior. I think WPML has the notion of non-translatable pages/posts which are displayed in every language. What we need is something similar, e.g. as someone said, adding an “ALL LANGUAGES” option in the page/post language selection drop down list in the dashboard.
I’m ready to donate for this! or try stuff in code.
