List amounts hidden in a cell that total the amount in that cell

[duepro2014]

Might be a stupid question. I have an amount in a cell. I have items with amounts that total up to the amount in the cell that i do not want the viewer to see unless they click on it. Is there a formula that can create the hidden list?

From the data ribbon you can create a collapsible group or subtotal.
