AI-generated Key Takeaways
-  Spreadsheet groups associate contiguous rows or columns that can be expanded or collapsed to hide or show content. 
-  Each group has a control toggle to expand or collapse the group as a whole. 
-  The depth of a group indicates its nested position within larger groups. 
-  The collapsed state determines if a group remains collapsed or expanded after a parent group is expanded. 
-  Groups can be manipulated using methods like collapse(), expand(), and remove(). 
Access and modify spreadsheet groups. Groups are an association between an interval of contiguous rows or columns that can be expanded or collapsed as a unit to hide/show the rows or columns. Each group has a control toggle on the row or column directly before or after the group (depending on settings) that can expand or collapse the group as a whole.
The depth of a group refers to the nested position of the group and how many larger groups contain the group. The collapsed state of a group refers to whether the group should remain collapsed or expanded after a parent group has been expanded. Additionally, at the time that a group is collapsed or expanded, the rows or columns within the group are hidden or set visible, though individual rows or columns can be hidden or set visible irrespective of the collapsed state.

Detailed documentation
 collapse() 
 
 Collapses this group.
const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; const range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 2 , 1 ); // Collapses this group. group . collapse ();
Return
  Group 
 
— This group, for chaining.
Authorization

 get  
 
 Returns the control toggle index of this group. This is the index just before the range when the control toggle is shown before the group, or the index just after the range otherwise.
const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; sheet . setRowGroupControlAfter ( true ); const range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 2 , 1 ); // Returns 4 const controlIndex = group . getControlIndex ();
Return
 Integer 
— The control toggle index of this group.

const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; const range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 2 , 1 ); // Returns 1 if the group is at depth 1. const depth = group . getDepth ();
Return
 Integer 
— The depth of this group.

 get  
 
 Returns the range over which this group exists.
const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; let range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 1 , 1 ); // Returns the range 2:3 if the group is over rows 2:3 range = group . getRange ();
Return
  Range 
 
— The range over which the group exists.

 is  
 
 Returns true 
if this group is collapsed.
const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; const range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 2 , 1 ); // Returns true if the group is collapsed. const isCollapsed = group . isCollapsed ();
Return
 Boolean 
— true 
If this group is collapsed; returns false 
otherwise.

 remove() 
 
 Removes this group from the sheet, reducing the group depth of the  range 
 
by
one. This may modify other groups. After calling this, the group object becomes invalid to use.
const sheet = SpreadsheetApp . getActiveSpreadsheet (). getSheets ()[ 0 ]; let range = sheet . getRange ( '2:3' ); range . shiftRowGroupDepth ( 1 ); const group = sheet . getRowGroup ( 2 , 1 ); // Removes this group range = group . remove ();
