I'm new to drupal 8. I have a content with couple of custom fields in it. Let's say its name is Title In Header. So whenever you need to add new content you have to fill this too.
Now this whole content is in Content Block (And Content Block is in Content region).
My template has Header region, Content region and Footer region.
My problem is that I want to have access to that custom field (Title In Header) in a block in header region. But I don't know how to do this and what block should I use to add it in header region. I think it's not a good approach to add another Content Block in Header region to show just a custom field as it shows the whole content. So what should I do?
