Initial release of CKEditor Content Groups.
Adds three content-grouping widgets to CKEditor 5 — accordion, horizontal tabs and vertical tabs — configured from inside the editor, producing semantic, framework-free markup (/ and ARIA tab roles).
Includes an optional submodule, CKEditor Content Groups Schema, that outputs JSON-LD structured data (FAQPage for accordions, ItemList for tabs) for SEO.
Requires Drupal core 10 or 11 and the core CKEditor 5 module. See the project page for full installation and configuration documentation.
