I have a spreadsheet I'm working on where I'd like checkboxes to be able to "open" subsequent columns when checked-off. To give more information, I currently have Checkboxes in every row in "column C" and I would like them to reveal the hidden columns of D & E only for specific rows in which the check box has been marked off. Is that possible?

I'd be open to using methods that don't include checkboxes if it's possible to achieve this in other ways.

Thanks!
