To add a new version of content in a new language, open the content from the Content Search tab and select the language from the language dropdown in the top left corner.
The first time you create a version of content in a new language, you'll be prompted to choose if you want to populate the content from the existing content in another language. To preserve the placement of links, images, files and other references in the content, choose Yes.
Previewing Content by Language
To preview content in a specific language, go to the Site Browser and open a page that displays the content. Change the display language for the page, and the content pulled by the page will be displayed in the selected language.
Pulling Content in the Default Language
Whenever a page is displayed in a specific language, all content on the page that exists in the chosen language will be displayed. However dynamic pages can (and should) be built to pull a default language version of content if there is not a version of the content that matches the front end user's language choice on a particular page. In addition, dotCMS system properties can be configured to automatically display the version of content in a default language if versions do not exist in the current display language (regardless of the page configuration).
For more information on configuring dynamic pages to pull default language versions of content see the Building Multilingual Sites documentation.
