Anybody can add drop-down lists in his/her workbook. Select a cell or a group of cells (ex: A1:A12) go to the menu bar Data/Validation, select "List" in the "Allow" text box and in the "Source" text box submit a list of values separated by commas (John, Mark, Joe, Peter) or a range of cells (ex: =B1:B5). Click OK. Now when you select any of the cells A1 to A12 a small arrow appears at the right of the cell. Click on it and you are offered a selection of the values that you have submitted or of the values that you have entered in cells B1 to B5. |
