Multilingual

Volto provides support for Plone's multilingual feature through the Plone core add-on plone.app.multilingual. It is included with Plone 5 and later. You can enable it through the Add-ons control panel in the administrative interface.

Volto configuration

You need to enable multilingual in Volto's configuration object.

import config from '@plone/volto/registry'

config.settings = {
  ...config.settings,
  isMultilingual: true,
  supportedLanguages: ['en', 'de', 'ca', 'pt-br'],
  defaultLanguage: 'en'
}

Declare the language you want to support in your site in the supportedLanguages array, and which is the default language of your site.

Warning

The default language and the supported languages must match those set in the Plone backend. Those should be set either using GenericSetup using your policy package or manually via the Languages control panel. Examples include en for English, or pt-br for Portuguese (Brazil).
