CellGroup

CellGroup[{cell1, cell2, ...}]
gives an open group of cells that can appear in a Mathematica notebook.
CellGroup[{cell1, cell2, ...}, 1]
gives a cell group in which only the first cell is open.
CellGroup[{cell1, cell2, ...}, -1]
gives a cell group in which only the last cell is open.
CellGroup[{cell1, cell2, ...}, {i1, i2, ...}]
gives a cell group in which cells i1, i2, ... are open.
  • If any celli is a string or Text object, it will be wrapped with TextCell. If it is any other type of expression, it will be wrapped with ExpressionCell.
You can nest one cell group within another:
Show only the first cell in the group:
Show only the second cell in the group:
Show only the first and last cells:
By default, notebooks use automatic grouping that ignores CellGroup structures:
