There are a couple of folding mode packages available on the emacs wiki.
I sometimes use one that works quite well. There was an older one which
I used a lot back in emacs 20 days. From memory, some of the folding
modes became a little dated and some a little unstable once overlays
were introduced into emacs. The biggest problem appears to have been
lack of maintenance. 

The mode I sometimes use (many of them are just called folding.el or
folding-mode.el, which makes it a bit confusing

;;; Commentary:

;;{{{ Introduction

;; Preface
;;
;;      This package provides a minor mode, compatible with all major
;;      editing modes, for folding (hiding) parts of the edited text or
;;      program.
;;
;;      Folding mode handles a document as a tree, where each branch
;;      is bounded by special markers `{{{' and `}}}'. A branch can be
;;      placed inside another branch, creating a complete hierarchical
;;      structure.
;;
;;      Folding mode can CLOSE a fold, leaving only the initial `{{{'
;;      and possibly a comment visible.
;;
;;      It can also ENTER a fold, which means that only the current
;;      fold will be visible, all text above `{{{' and below `}}}'
;;      will be invisible.
;;
;;      Please note, that the maintainers do not recommend to use only
;;      folding for you your code layout and navigation. Folding.el is
;;      on its best when it can "chunk" large sections of code inside
;;      folds. The larger the chunks, the more the usability of
;;      folding will increase. Folding.el is not meant to hide
;;      individual functions: you may be better served by hideshow.el
;;      or imenu.el (which can parse the function indexes)
