I use expressions to create "control panels" to set dynamic variables to control the evaluation of other expressions in a large notebook. For example: enter image description here I would like the expressions that create these grids to hide themselves after evaluation, so I have a cleaner notebook showing controls, but hiding expressions. How can I do this?

    $\begingroup$ You could add SetOptions[EvaluationCell[], CellOpen -> False] as last command in the cell (to open it, see @kglr's comment). You can also put this code in the CellEpilog option, possibly connected to a custom style, so that you can just set the cell style to make it auto-hide. $\endgroup$ – Lukas Lang Sep 5 '19 at 16:49

Probably the best what you can do is to collapse the cell group keeping visible only the output cell(s).

If your input cell produces only one output cell, you can define an auxiliary function printAndCollapseInputCell as follows:

printAndCollapseInputCell = 
 Function[CellPrint[ExpressionCell[#, "Output"]]; 
  SelectionMove[EvaluationCell[], Next, "Cell"]; FrontEndTokenExecute["OpenCloseGroup"]];

Now you can apply it to your expression:



Or alternatively if your input cell outputs/prints more than one cell, you can define an auxiliary function hideInputCell which should be put at the last (and separate!) line of the input cell:

hideInputCell := (SelectionMove[EvaluationCell[], All, "CellGroup"]; 
  Module[{nb = EvaluationNotebook[], group}, group = NotebookRead[nb]; 
    group /. CellGroupData[cells_, ___] :> 
      CellGroupData[cells, Range[2, Length[cells]]]]];)
