This question is a follow up question to Exporting Summary Boxes.
When cutting away the "Head" of a summary box is there a better way than doing the following?
result = ConvolutionLayer[4, 8]; boxData = (result // ToBoxes // ReplaceAll[HoldPattern[Typeset`open = _] :> (Typeset`open = True)] ) boxData[[1, 1, 1, 1, 3]] // RawBoxes
Since just accessing the particular element seems very inelegant and might be prone to errors in the future. Ideally it would cut the + aswell.
