To enable a dropdown with an "all" option you can use data validation for the dropdown list, and a formula based on IF, SUM, and SUMIF functions to calculate a conditional sum. In the example shown the formula in G5 is:


where "color" (C5:C15) and "qty" (D5:D15) are named ranges.


When F5 is selected, the following dropdown appears:

Dropdown sum with all option in action

When the user makes a selection, the correct sum is returned.

Generic formula



The dropdown is set up with a simple data validation rule based on a "list":


The named ranges "color" (C5:C15) and "qty" (D5:D15) are for convenience only.

The formula in G5 performs a conditional sum based on the current dropdown selection in F5. The outermost function is an IF statement, which checks if the selection is "all":


If so, the formula returns the sum of quantity column as a final result.

If F5 is any value except "all" (i.e. "red", "blue", or "green"), the logical test returns FALSE and IF routes the formula to the SUMIF function:


SUMIF calculates a conditional sum based on the value in F5 and returns the result.
