If your BigCommerce store is available in several languages, you can translate the Customize button using the translation solution you already use for your storefront.
Kickflip doesn't translate the button text
The Button label you set in the Kickflip dashboard is a single text, shown in every language of your store. Kickflip doesn't currently let you enter a different label per language.
How multilingual BigCommerce stores work
BigCommerce Stencil storefronts don't translate content natively. Multilingual stores usually rely on a third-party translation app from the BigCommerce App Marketplace.
These apps translate the content of your pages as it's displayed, including elements added by other apps. That's why they can translate the Customize button too, just like the rest of your storefront.
Translating the button with your translation solution
We recommend handling the Customize button through your store's existing translation solution:
In the Kickflip dashboard, set Button label in your store's default language, then click Save.
Open a customizable product on your storefront so the Customize button appears.
In your translation solution, translate the button text like any other text of your storefront.
Switch your storefront to another language and check that the button shows the translated text.
If the button isn't translated, check your translation solution's documentation or contact its support team.
