You can set a **default language** such as Thai, English, Chinese, or Japanese, and the banner will change accordingly. --- ## Setting Language via HTML Tag By default, Cookie Wow detects the page language from the `` attribute. This means: * `` → displays the banner in **Thai** * `` → displays the banner in **English** * `` → displays the banner in **Chinese** * `` → displays the banner in **Japanese** This automatic detection is ideal for multilingual sites following HTML standards. --- ## Dynamically Changing Language with JavaScript API If your site is a **client-side web application** and does not reload the full page when changing languages, you can manually switch the Cookie Banner language using the following JavaScript commands: ```javascript window.cwcCookieBanner.setLang('th'); // Thai window.cwcCookieBanner.setLang('en'); // English window.cwcCookieBanner.setLang('zh'); // Chinese window.cwcCookieBanner.setLang('ja'); // Japanese ``` Before displaying the banner in multiple languages, make sure that you have added content (e.g., texts, descriptions) for each language in the Cookie Wow dashboard. If content exists for each language, the banner will automatically display the correct version based on the current language setting.
