# Multi-language Surveys
> Create surveys that support multiple languages using translations. This helps you reach a diverse audience without making separate surveys for each language. It also simplifies survey creation, delivery, and analysis for multilingual audiences.
How to deliver a specific language depends on the survey type (app or link survey):
* App & Website survey: Set a `language` attribute for the user. [Read this guide for App Surveys](#app-surveys-configuration)
* Link survey: Add a `lang` parameter in the survey URL. [Read this guide for Link Surveys](#link-surveys-configuration)
***
## Creating a Multi-language Survey
Go to Configuration and open the **Survey Languages tab**:
Click on the **Edit languages** button to add a new language to your survey.
Select the preferred language from the dropdown and assign an identifier Alias. Click the **Add language** button to add the language to your project:
You can come back to this page anytime to add more languages or remove existing ones.
Return to the dashboard to create a new survey or edit an existing one:
In the survey editor, scroll down to the **Multiple Languages** section at the bottom and enable the toggle next to it:
Choose a **Default Language** for your survey.
Changing the default language will reset all the translations you have made for the survey.
Add the languages from the dropdown that you want to support in your survey:
You can now see the survey in the selected language by clicking on the language dropdown in any of the questions.
Now you can translate all survey content, including questions, options, and button placeholders, into the selected language.
Once you are done, click on the **Publish** button to save the survey.
## App Surveys Configuration
After you setup the Formbricks SDK for your user, you can call the `setLanguage` function with the language code. This can be either the ISO identifier or the Alias you set when creating the language. The `language` attribute makes sure that this user only sees surveys with a translation in this specific language available.
```js theme={null}
Formbricks.setup({
environmentId: "",
appUrl: "", // use PUBLIC_URL if you are using multi-domain setup, otherwise use WEBAPP_URL
});
Formbricks.setLanguage("de"); // ISO identifier or Alias set when creating language
```
If a user has a language assigned, a survey has multi-language activated and it is missing a translation in
the language of the user, the survey will not be displayed.
That's it! Now, users with the language attribute set will see the survey in their preferred language. You can start collecting responses in multiple languages and filter them by language on the summary page.

## Link Surveys Configuration
For link surveys, the translation delivery is dependent on the `lang` URL parameter.
After publishing the survey, just copy the survey link and append the `lang` query parameter with the language alias you have set.
For example, if you have set the alias for French as `fr`, you can share the survey link as
[`https://your-survey-url.com?lang=fr`](https://your-survey-url.com?lang=fr)
Here are two examples:
* English: [https://app.Formbricks.com/s/clptfos2i1pj516pvhxqyu3bn?lang=en](https://app.Formbricks.com/s/clptfos2i1pj516pvhxqyu3bn?lang=en)
* German: [https://app.Formbricks.com/s/clptfos2i1pj516pvhxqyu3bn?lang=de](https://app.Formbricks.com/s/clptfos2i1pj516pvhxqyu3bn?lang=de)
Without the `lang` parameter, Formbricks will show the survey in the default language you have set.
You can now start collecting responses in multiple languages!

## RTL Language Support
Formbricks fully supports Right-to-Left (RTL) languages such as Arabic, Hebrew, Persian, and Urdu. When you add an RTL language to your survey, the survey interface automatically adjusts to display content from right to left.
### How RTL Support Works
* Text alignment automatically switches to right-to-left
* Survey layout and UI elements adjust to RTL orientation
* Button placement and navigation flow adapt to RTL reading direction
* Form elements maintain proper RTL formatting
### Setting Up RTL Languages
Add an RTL language (like Arabic or Hebrew) in the **Survey Languages** settings
Create translations for your survey content in the RTL language
The survey will automatically display in RTL format when that language is selected
