Hello,
Is it possible to add the Chapitre template to the list of structured sources - along with the already available Site web (Cite web), Ouvrage (Cite book) and Article (Cite journal) - in the VisualEditor? With these three templates, Chapitre (="Chapter") is one of the main structured sources in the French Wikipedia: we can link the sfn templates to it, for instance.
The template and its TemplateData are well documented in French.
Regards,
