Features

CKEditor 5 Definition List Fix improves support for semantic HTML definition lists in Drupal's CKEditor 5 integration.

By default, CKEditor 5 may transform or normalize definition list markup in unexpected ways, including:

Converting <dt> elements into paragraphs
Inserting unwanted

tags inside <dt> or <dd>
Altering valid semantic definition list structures during editing

This module provides a lightweight CKEditor 5 plugin that preserves proper definition list markup while editing content.

Features include:

  • Preserves <dl>, <dt>, and <dd> elements in CKEditor 5
  • Prevents unwanted paragraph insertion inside <dt>
  • Supports semantic HTML definition lists
  • Works directly inside the CKEditor 5 editing experience
  • Lightweight implementation with no external libraries required
  • Compatible with Drupal 10 and Drupal 11

Typical use cases include:

  • Accessibility-focused websites
  • Government and enterprise websites
  • Technical documentation
  • Glossaries and dictionaries
  • FAQ layouts using semantic HTML
  • Structured editorial content

Post-Installation

After enabling the module:

  1. Go to: Administration » Configuration » Content authoring » Text formats and editors
  2. Edit the text format where CKEditor 5 is enabled.
  3. In the CKEditor 5 toolbar configuration, enable: Definition List Fix Plugin
  4. Save the text format configuration.

The module works automatically after the plugin is enabled for a text format.

No additional configuration pages are required.

Example supported markup:

<dl>
  <dt>Term</dt>
  <dd>Description</dd>
</dl>

The module is designed to preserve valid semantic definition list markup during editing and saving.

Additional Requirements

No additional modules or external libraries are required.

Requirements:

  • Drupal 10 or Drupal 11
  • CKEditor 5 (included with Drupal core)
