I'm not sure. However, from the docs for set-selective-display

C-x $ runs the command set-selective-display
    which is an interactive compiled Lisp function in `simple'.
(set-selective-display ARG)

Set `selective-display' to ARG; clear it if no arg.
When the value of `selective-display' is a number > 0,
lines whose indentation is >= that value are not displayed.
The variable `selective-display' has a separate value for each buffer.
