With Excel data validation you can create drop down lists on a worksheet. In this example, you can select multiple items from the drop down list, and the new items are automatically added to the existing selections in the cell.
If an item has been selected before, in the current cell, that item will be removed, if you select it again.
This video shows how the multiple select and remove features works. You can also see the Excel VBA code, and the steps that it goes through, when you make a selection in the drop down list.
You can download the sample Excel file for this technique, at the link shown at the start of this description.
Nice tutorial but I've one question. How do I get the code from the SameCell sheet to work in protected sheet? The code works in nonprotected as shown.
