Read-only Tree view

Hi, I wonder if there is a way to show only the Tree view (no Code view) in read-only mode. We don't want the left toolbar as well as the top blue toolbar. Is there an option to turn those off?
Also, it is possible to show a line from the beginning of an array/object to the last element of the array/object as the jstree in this link? https://codepen.io/jjsjjja/pen/VoGYRB. (You can look at the bottom left white dashboard in that link)

Thanks,
Vanessa
