I am creating a spreadsheet for work which contains all different customers on it. The top row is frozen, and i am trying to make a pull down menu on that top row so i can just click on a certain customer and have all of them come up. I know that it can be done, I just can't figure out how. I figured out how to create the drop down list through the Validate option, but that just fills in that cell with whatever customer I choose, I am trying to sort them. Can someone please help!!
