I have tried to insert the AutoCollapse command defined in this nice answer

How to Keep Input Cells Hidden After Evaluating Notebook

inside a Button

  Button["Input Délétion OK", 
  AutoCollapse[] := (If[$FrontEnd =!= $Failed, 
  SelectionMove[EvaluationNotebook[], All, GeneratedCell];
  FrontEndTokenExecute["SelectionCloseUnselectedCells"]])]
  AutoCollapse[]

But AutoCollapse[] stay blue and unevaluated or is evaluated and then unevaluated --- MA 10.1. Any idea ?

  • What are you trying to accomplish? Do want a button that can enable and perhaps disable the action of having AutoCollapse[ ] as the last evaluation item in a multi-expression input cell? – m_goldberg Nov 15 '16 at 15:36
  • Mainly, I want to hide the code, but I do not want to to it globaly but after verification of each input. – cyrille.piatecki Nov 15 '16 at 18:14
  • AutoCollapse is not defined unless you click a button. And button itself does not evaluate AutoCollapse[] so I'm quite confused why it was left outside. Can you clarify? – Kuba Apr 13 '18 at 08:05
