Hi Arno,
Thanks for your message.
Yes, I know. But my request is not to integrate a file in the body of the article, but to link an article to a related file and to have a link in the header of the article.
Furthermore, regarding the categories, these are a completely separated from the category structure of the articles. I would be great to have the possibility of a "match" between both category structures, or simply to reflect the category structure of the articles.
Rgds,
