  I am using Angular with Wijmo grid.

  I followed this to do my custom grouping.
  
  https://www.grapecity.com/wijmo/demos/Grid/columns/columngroups

  I found “collapseTo” is the property to control which column to display after grouping.
  
  The problem is “collapseTo” is a string type, so just one column is displayed after grouping.

  Is it possible to display more columns after grouping?
  
  For example, in this case https://www.grapecity.com/wijmo/demos/Grid/columns/columngroups. Under “Perf” header, instead of “YTD” column, I hope to display “1M” and “6M” columns after I click the minus button on the header,…

  Hi Wang,

  We are sorry but this is not possible. The collapseTo property only works with a single column.

  Hello ashwin.saxena,

  Thanks for you reply.
  
  Maybe I can do something with onColumnGroupCollapsedChanged event?
  
  How do I prevent the default behavior of the collapse? So I could use columns.hide() or something to do my custom grouping.

  Hi again,

  I tried with the columnGroupCollapsedChanged and it seems to work according to your requirements. Thank you for the suggestion.
  
  Instead of a hide method, you may use the visible property of the Column to display the child column. You may refer to the sample link below for reference:

  The tricky is SetTimeout…

  Thank you very much for your support !
