Multilingual Data Layer

Configure a custom window.dataLayer payload for every enabled Drupal language using YAML—without writing PHP or JavaScript.

Features

• Provides optional global YAML and one YAML field for each enabled language.
• Lets site builders choose their own keys, values, nested objects, and lists.
• Merges language-specific values over shared global data.
• Can add the current request URI and Drupal language ID under configurable keys.
• Shows a JSON preview of the merged YAML for each language.
• Safely initializes window.dataLayer and pushes one object.
• Produces no script when the effective payload is empty.
• Provides an alter hook for developers who need additional logic.

The module supplies data only. It does not install Google Tag Manager, add a container snippet, or send analytics events.

Post-installation

Go to Configuration > Regional and language > Multilingual Data Layer. Add optional shared YAML, then add values for each language that needs them. Save the form and inspect the previews or window.dataLayer in the browser.

Additional requirements

Requires the Drupal core Language module. No external service or JavaScript library is required.

Recommended modules/libraries

Use a Google Tag Manager or other analytics integration when the configured values need to be collected externally.
