Users with the ADMIN or PORTAL_ADMIN role can use the Localized label component to add interface labels available in multiple languages. When the user changes their interface language (using the Interface language selector component, or the selector available in the Profile menu), the labels adapt to the choice of the user.
If a label has no translation, it defaults to the fallback language.
If the design of a page differs from one language to another, it is possible to create one page per language.
