title: Emacs: Is it possible to fold (collapse/expand) json objects/collections?
body: <p>Windows 10 (64 bit), Emacs 25.1.</p>
  
  <p>Suppose I have big json file. And it's very comfortably if I can folding (collapse/expand) any node of this json. I do this by Notepad++. </p>
  
  <p>Here example:</p>

  <p>Is it possible to do same in Emacs? 
  Thanks.</p>
