Explain the multilingual capabilities in Communities.
Community content can be maintained in different languages within a single community. A default language serves as the base language and additional community languages enabled. Content can be translated in Community Builder or using XML files.
Before additional languages can be added to a community, a default language must be defined. It serves as the base language when creating new community content.
The default language and the additional community languages can be added, removed, and configured under Settings > Languages in Community Builder.
The order of languages in the list defines how the languages appear in the language selector. Additionally, the label of the languages can be changed and is reflected in language selectors.
Languages can also be set to active or inactive in live communities. Inactive community languages do not appear in the Language Picker component to external users.
For each community language, a fallback language can be specified. This defines which languages version of a piece of content should be displayed if no translation for the selected community language exists.
Community members cannot change the language of communities by default. To allow members to choose an active community language, the Language Selector component must be added to a community page.
