How to Add a Drop Down Box in Excel 200

Adding a drop-down box, also known as a drop-down list or data validation, in Excel 2003 is a simple process that can help ensure data accuracy and consistency. Here's how to do it:

1. Open the Excel spreadsheet where you want to add the drop-down box.

2. Select the cell or cells where you want to add the drop-down box.

3. Go to the "Data" menu at the top of the screen and select "Validation."

4. In the "Validation" window that appears, select the "Settings" tab.

5. Under "Allow," select "List" from the dropdown menu.

6. In the "Source" field, enter the list of items you want to appear in the drop-down box, separated by commas. For example, if you want the drop-down box to contain a list of fruit, you could enter "apple, banana, cherry" (without the quotes).

7. Optional: Under "Input Message" and "Error Alert," you can enter text that will appear when the user selects the cell or enters invalid data.

8. Click "OK" to close the "Validation" window.

Now, when you click on the cell with the drop-down box, a small arrow will appear next to it. Clicking on the arrow will display the list of items you entered in step 6. The user can then select one of these items from the list.
