I want to set a field group after the title. But in Edit Field Group" > Settings I can only choose "After content" and "Side". Where are the other alternatives, such as "After Title" (there seems to be more "Context" options - https://docs.metabox.io/creating-meta-boxes/)? Are they only available if I code the Field Group? If so, why?
I see now that it is because I have the Gutenberg Editor AND that the custom post type Supports "Editor" (https://support.metabox.io/topic/advise-on-implementing-subtitle-custom-field/). If I deactivate "Editor", I also get the Position options "After post title" and "Before post title". And then I can use the field "WYSIWYG" to get a traditional editor.
