How would I make one section collapsed by default, but not the other? Also, which Discourse feature would I use to make sections?

I’m just thinking about how to do it, It would have to be done in a plugin. Ultimately, a translation could be a type of reply. Creating it would wrap the content in a div with a class to indicate its language.
I’ll try out a few things and get back to you.

There should be a plugin for Discourse for collapsable sections, if I remember correctly. It would be nice to make them auto-collapse or auto-expand based on the current locale. More generally, depending on any user field.

> Auto switch via querystring might be possible
I can’t find info/solution on the topic. I have the exact same requirement, need to redirect users on the forum but with a selected language. A query string approach can be ok, any other approach is welcome too.
@hongquan did you find a solution at the end?

Not yet. I have stopped working with Discourse.

I continue a bit my exploration. Seems that the language selection happens here:
>
Currently, it’s pretty easy simple and straightforward. What if we complete that with a possibility to force the locale by query-string:
```
if params[:locale].present?
locale = locale_from_locale_param
else if SiteSetting.set_locale_from_accept_language_header
locale = locale_from_header
else
locale = SiteSetting.default_locale
end
```
If will allow use case like requested by @hongquan on [Switch language via URL? - #3 by hongquan](https://meta.discourse.org/t/switch-language-via-url/28937/3)
This have no impact on existing instances and it’s not impacting already created user, it will only help user that have already select a language in the main website to continue browsing in the same language in the forum section…
Is this something I can provide as a PR or should I look at doing this in a plugin? (although I’m not sure it’s possible to do this in a plugin…)

Adding the ability to set the locale through a query string could be done through a plugin. The code for setting the locale through the Accept Language header was initially in a plugin: [https://github.com/scossar/variable-language](https://github.com/scossar/variable-language)
There is an issue with setting the locale for anonymous users for on sites that are using a CDN. It can cause the wrong locale files to be served to anonymous users. See: [Swedish? meta just showed me the UI in Swedish](https://meta.discourse.org/t/swedish-meta-just-showed-me-the-ui-in-swedish/41137). For this reason, I think the approach that you have brought up in this post - [Set language for SSO users - #5 by jeanmonod](https://meta.discourse.org/t/set-language-for-sso-users/78458/5) - would be a better candidate for a PR.

Ok, I will go the plugin way to start, let’s see then if you have the interest to integrate that into the core.

I’m not sure I understand the issue correctly, but I can understand the potential problem of caching pages that are built upon a user header such as `HTTP_ACCEPT_LANGUAGE `. Here we are talking about a query string, so the CDN should cache the answer separately…

It’s really two separate topics:
- The query string will help me to provide the appropriate interface to an anonymous user.
- The SSO extension should help me to avoid all user accounts to be created with the default locale.
Ok, in the coming days I will start to work on those two plugins, just ping me if you think I should do PR instead.
Thanks for your help so far

Did you solve this? We want to use the Swedish language as well, but we cannot even get the main installation to change from English to Swedish. It is completely stuck on the English installation, which I do not want to present to a Swedish audience.

As of this commit from @david, this should work cleanly now 🎉
