So I'm trying to set up a custom field type where I can save references to scientific articles (including the link to the article).
Then I want to use a shortcode to show these references as an ordered list in the content.
I think for this, I need a custom field type of type HTML.
But I can't seem to make it work with custom HTML field type. That field type doesn't allow me to put in any content in the editor of a specific post.
Is there any way to do this?
