CKEditor 5 Enhances Drupal Modules with Merge Fields, Email Export, and Source Editing Updates
CKEditor has rolled out updates to its Premium Features and Plugin Pack modules for Drupal, adding Merge Fields, inline CSS export, and a dark theme for source editing—key tools for building structured email content and improving editing workflows.
Announced by Gökçe Tosun in a CKEditor blog post, the September 2025 release includes Premium Features v1.6.0 and Plugin Pack v1.4.1. These updates target high-precision content tasks such as personalized email generation, HTML formatting, and embedded media integration.
Key Feature: Merge Fields
The Merge Fields plugin, part of the CKEditor 5 Premium Features module, integrates with the Drupal Token API to allow placeholder-based personalization inside the editor. Placeholders remain intact during editing and are dynamically replaced during export or email delivery.
Email Styling: Export with Inline CSS
Also within the Premium Features module, the new plugin exports HTML content with inline styles, ensuring compatibility across varied email clients. This builds on previous features like the Email Configuration Helper and Layout Tables plugin.
Dark Theme for Source Editing
The Enhanced Source Editing plugin now includes a dark mode interface, improving usability for developers working in low-light environments. This is part of the Premium Features module and enhances readability for raw HTML editing.
Other Premium Module Improvements
- Deprecated functions removed; core version requirement raised to Drupal 10.3
- PHP 8.4 compatibility added
- Improved version checks and OpenAI model settings
- Fixes for collaborative workflows and documentation links
Plugin Pack Updates
The CKEditor 5 Plugin Pack module adds a Media Embed plugin for direct insertion of rich media content. Version 1.4.1 also includes improvements such as:
