The steps to create a drop-down list in Excel are as follows: 1. Prepare the option content, list the options in a certain area of the table, such as G1:G5, and make sure it is not repeated; 2. Use the data verification function, select the target cell, enter the "Data Verification" window, select "Sequence", specify the source area and check the "Provide drop-down arrow"; 3. Optionally set the input prompts and error warnings, and fill in the corresponding content in the "Input Information" and "Error Warning" tabs respectively to improve the user experience. After the above steps are completed, the user can select the preset option through the drop-down arrow to avoid manual input errors.

Creating a drop-down list in Excel is actually quite simple and very practical, especially suitable for data entry forms. It can limit users to only select from preset options to avoid typing incorrect content.

1. Prepare the options

The content of the drop-down list is not written directly in the settings, but requires listing all the options somewhere in the table first. For example, if you want to create a "department" drop-down box, you can write "Human Affairs Department, Technology Department, Marketing Department, Finance Department, Operation Department" in a certain area (such as G1:G5).

• Try not to repeat the options
• It is recommended to place it in a separate area or worksheet for subsequent maintenance

If you want to change the options later, you only need to update this area without resetting the entire drop-down box.

2. Use the data verification function to add a drop-down menu

Select the cell where you want the drop-down box to appear, and then click "Data" → "Data Verification" → "Data Verification" pop-up window on the menu bar.

Select Sequence in the "Allow" drop-down, and then select the option area you just prepared in "Source". Remember to check the "Provide drop-down arrow" item, otherwise the small triangle icon will not be displayed.

Note: The source must be a fixed range in the same table and cannot be referenced across tables unless it is named ranges.

After setting, click "OK", and you should see a small triangle on the right side of the cell.

3. Set error prompts and input information (optional)

In the same data verification window, you can switch to the "Input Information" tab and fill in the title and prompt information when entering, such as "Please select the department name". In this way, the user will automatically pop up when the mouse clicks in.

You can also set warning information if the user enters non-optional content in "Error Warning", such as "Manual input is not allowed".

Although these settings do not affect the function, they can make users more clear about how to operate and reduce misoperation.

Basically these are the steps. It seems a bit too much, but it is very fast to operate and can be done in one minute after proficiency. The key is to list the options first and don’t miss the “providing drop-down arrow” check.
