Hi Leo,
in fact I was looking for the possibility of customizing the pages of the categories.
By doing a search I saw this plugin
https://wordpress.org/plugins/enhanced-category-pages/
pity that it is no longer updated
The result I want to get for the category pages is to have a page that can be customized with an image at the top under the menu and then, defaul all posts for that category will be inserted.
If you have a plugin or other solution I would be grateful.
Thanks
Paolo
