The Drupal 11.4.0 release notes (1 July 2026) say CKEditor was updated to CKEditor 5 version 47.6.2. Patch releases can move it: in Drupal 11.4.10, core/core.libraries.yml declares version 47.6.3-drupal.1 for the ckeditor5 library. Look in that file on your own site for the exact number.
' - '@type': Question name: 'Why is the Allowed HTML tags field read-only?' acceptedAnswer: '@type': Answer text: 'With CKEditor 5, the enabled toolbar buttons and plugins decide which tags and attributes are allowed, so Drupal generates the list and locks the field. Core's own help text says that removing tags by hand would break enabled features. To allow more tags, enable the Source editing plugin and list them under Manually editable HTML tags.
' - '@type': Question name: 'Can I still use CKEditor 4 with Drupal 11?' acceptedAnswer: '@type': Answer text: 'Not from core. Drupal.org states that CKEditor 4 was removed from core in Drupal 10 and calls it end-of-life. The contributed CKEditor 4 project page (checked 26 October 2026) marks the module Unsupported and Obsolete and outside the security advisory policy. Drupal.org strongly recommends moving to CKEditor 5.
' - '@type': Question name: 'Is CKEditor 5 free to use in Drupal?' acceptedAnswer: '@type': Answer text: 'CKEditor's licensing page says its open-source distribution is licensed under GPL 2 or later, and that it sells commercial plans. The contributed CKEditor 5 Premium Features module adds paid plugins such as real-time collaboration and requires a license key; its project page lists a stable release 1.8.6 from 14 October 2026 for Drupal 10.3 or 11.

It gives editors a toolbar for headings, bold text, links, lists and images inside text fields, and Drupal stores what they write as HTML. Each text format decides which editor it uses and which HTML tags survive. In Drupal 11.4, it is the only rich text editor that ships in core. ## How it works in Drupal 11 CKEditor 5 is a core module named `ckeditor5`. It builds on the core Editor module, which keeps one editor configuration for each [text format](/hc/documentation/learn-drupal/drupal-glossary/text-format). For CKEditor 5, that configuration lists the toolbar items and the settings of each plugin. In Drupal 11.4.10, the Standard installation profile ships this configuration for Basic HTML and Full HTML; it ships none for Restricted HTML. You manage it at `/admin/config/content/formats`. In the admin menu the link sits under Configuration › Content authoring, and the page title is Text formats and editors. The editor form has the sections *CKEditor 5 toolbar configuration* and *CKEditor 5 plugin settings*. Every toolbar button belongs to a plugin. Core defines its plugins in `ckeditor5.ckeditor5.yml`. A module adds its own in a file named `{module_name}.ckeditor5.yml` and can change existing definitions with `hook_ckeditor5_plugin_info_alter()`. The editor and the HTML filter work as a pair. When a format uses the filter named *Limit allowed HTML tags and correct faulty HTML*, CKEditor 5 fills in its Allowed HTML tags field from the enabled plugins and makes the field read-only. To allow tags that no enabled plugin covers, you use the Source editing plugin and its field *Manually editable HTML tags*. ## Status and history Checked on 26 October 2026: Drupal 11.4.0 came out on 1 July 2026, and its announcement says text formats using CKEditor can now include a Fullscreen plugin, which expands the editor to the whole browser viewport. The plugin is defined as `ckeditor5_fullscreen` in the core plugin file. ## Example An editor asks for a distraction-free writing view on long articles. A site builder opens `/admin/config/content/formats` and configures the Full HTML format. In the toolbar configuration, the builder moves *Fullscreen* from the available items into the active toolbar and saves. In the Standard profile of Drupal 11.4.10, the Full HTML toolbar does not include this button, so it has to be added. The same screen answers another request. If a page needs a definition list, the builder enables Source editing and types `
