WYSIWYG templates (CKEditor Templates)

As of September 2023, the CKEditor Templates module has no upgrade path to Drupal 10 but work is being done. Seeing that this is a major migration issue on the upgrade path, we will keep an eye on the issue. 

Introducing embedded content

The ability to add and edit rich design patterns using the WYSIWYG editor is a primary Sector content authoring feature. Looking ahead to Sector 10, we decided to provide an alternative solution using the Embedded Content module

If there is a Drupal 10 CKEditor Templates version available before the end of 2023, both solutions can work in tandem and site owners can decided which to choose. 

Other alternatives

The CKEditor 5 Template module is another alternative worth keeping in mind, but the CK5 templates are built more for editorial use cases in apps rather than websites. Try the templates button on the feature-rich editor demo

Migrating CK4 to CK5
