Localization

Note: You are currently reading the documentation for Bolt 4.0. Looking for the documentation for Bolt 3.7 instead?

Bolt comes with built-in localization for all fields by default. You do not have to install anything to use this. All it takes to use the localization feature in Bolt is to configure your Content Types and Fields to be translatable.

Localize Content Types

Bolt allows you to specify which languages are enabled for each Content Type. This is done using the locales setting in the contenttypes.yaml file:

pages:
    name: Pages
    singular_name: Page
    fields:
        heading:
            type: text
            class: large
            group: content
            localize: true
        subheading:
            type: text
            class: large
            localize: true
        slug:
            type: slug
            uses: [ heading ]
            localize: true
        photo:
            type: image
            label: "Eén plaatje"
            placeholder: https://source.unsplash.com/1280x768/?business,workplace/__random__
    locales: ['en', 'nl', 'ja', 'nb']

This will produce the following result in the editor:


Note: The locales setting for a content type only defines the allowed languages for the content type. You can control which fields are localizable on a per-field basis using the localize option (see below).

The above example will make the pages content type localizable: that means, editors will be able to create different versions of the same page in the specified 4 languages: English, Dutch, Japanese and Norwegian. To learn more about locales, visit the locales page.

Localize fields

Bolt allows you to specify which fields are localized within a content type separately. For example, you may want the title and content fields of your records to be translated, but not the image or file fields.

To configure a field as localizable (can be translated), use the localize option. Check the example above again:

pages:
    name: Pages
    singular_name: Page
    fields:
        heading:
            type: text
            class: large
            group: content
            localize: true # <- This field will be available in en, nl, ja and nb.
        subheading:
            type: text
            class: large
            localize: true # <- This field will be available in en, nl, ja and nb.
        slug:
            type: slug
            uses: [ heading ]
            localize: true # <- This field will be available in en, nl, ja and nb.
        photo:
            type: image
            label: "Eén plaatje" 
            placeholder: https://source.unsplash.com/1280x768/?business,workplace/__random__
            # <- This field will only be available in your default locale
    locales: ['en', 'nl', 'ja', 'nb']

By default, localize is set to false so that you only need to use localize: true if you want the field to be translatable.

Tip: The example above says that the photo field will be available in the default locale only. To read more about that, check the locales page.

Overriding the default locale

The example above says that the photo field will be available in the default locale only. That is, the locale configured in the services.yaml file.

Bolt provides 2 ways to specify the default locale:

  • To override the default locale for all your content types, visit the locales page
  • To override the default locale for a single field, use default_locale on that field, as shown below:
pages:
    name: Pages
    singular_name: Page
    fields:
        heading:
            type: text
            localize: true # <- This field will be available in en, nl, ja and nb.
            default_locale: 'nl'
    locales: ['en', 'nl', 'ja', 'nb']
