If it’s OK for people to leave the cell empty, check the Ignore blank box. Note that we left out the header row, because we don't want that to be a selection option: We put ours on a sheet called Cities, in range A2:A9.
On the Settings tab, in the Allow box, click List.Ĭlick in the Source box, then select your list range. Unlock specific areas of a protected workbook or stop sharing the worksheet, and then try step 3 again. Note: If you can’t click Data Validation, the worksheet might be protected or shared.
