Super.so uses Notion as its backend, so multilingual setups are not automatic. You will need to duplicate your notion page and translate it to the language you desired.
STEP 1 : Translate your Pages in Notion and Make Sure it is a Subpage
Ensure that each language version of your content is translated in Notion and organized as a subpage. This will allow you to link directly to each language from your site.
STEP 2: Create your Navigation In Super
Go to Languages Section
Click Add Language
Select Language and choose the page.
Hit Settings Icon
Click manage Navigation Settings
Add Item and set up your navigation menu
Save Changes
You can also set a CTA on each language thru this link: Custom CTA Button for Each Language
Pages Can Only Be Assigned to One Language
Once a page has been assigned to a language, it cannot be assigned to another language. Each page can only belong to one language at a time.
If you need to use the same content for another language, create a separate translated page in Notion and add it to Super before assigning it to that language.
