How to add a drop-down list in Excel (3 easy ways)

We come across drop-down lists on the internet and other software applications all the time. They are useful because they limit the options available to the user, as only pre-validated items can be selected. In this post, we’ll look at how to add a drop-down list in Excel.

In Excel, there are three different types of worksheet-based drop-down lists:

  • Data validation
  • Form control
  • ActiveX

So how do you know which one you should use? As with so many things, the answer is “it depends”. Let’s take a look at these three options and understand where to use each one.

Data validation drop-down list

The most common form of drop-down list is a data validation list. Let’s create one of these.

Enter the values to be used in the drop-down list into a range of cells; these are known as the ‘list items’.

Then select the cell in which the drop-down should exist.

Scenario for drop-down list

Click Data > Data Validation (drop down) > Data Validation…

The data validation dialog box opens. On the Settings tab, select list from the allow box, and enter the range of cells containing the list in the source box.

Data validation drop-down options

Click OK to close the data validation dialog box.

To use the drop-down, click on the cell containing the data validation list. We can now only select a value from the list.

Using a data validation drop-down list

Typing an invalid entry in the cell will result in an error message.

Other data validation list options

There is lots of flexibility in this type of drop-down list.

List input as hardcoded values

The list doesn’t have to be on a worksheet; the values can be hardcoded into the source field. The screenshot below shows how to include the options Yes, No and Maybe without using cells; each list item is separated by a comma

A drop-down list created in this way would look like this:

Yes No Maybe drop-down list

TOP TIP: If we need to use a comma in the list item text, press ALT+0130 to enter the comma, instead of a regular comma character.

List input as rows or columns

If using values in worksheet cells as the source, the list of values can be arranged in rows or columns (but not both at the same time)

List input as a named range

The list of values can be stored in a named range, provided it is a continuous range of rows or columns.

TOP TIP: If you can’t remember the name of the named range, press F3 and select from the Paste Name dialog box.

List input as a Table

I love Tables, but they don’t work as well with data validation lists as they should. Check out this post to find out how to make it work.

List input as dynamic arrays

If you have a dynamic array enabled version of Excel (only Microsoft 365 and Excel 2021), then data validation lists can contain the result of a dynamic array.

If the first cell in the output array were in cell A2, we could use =A2# as the reference in the source box. This method is excellent for advanced techniques, such as shrinking lists, or dependant lists.

Input messages

The Input Message tab of the data validation dialog box provides the settings to display a message when a user clicks the data validation cell.

The message is intended to provide guidance for the user so they know what type of information to enter.

We only need to provide a title and an input message.

Data validation drop down with input message

Make sure show input message when cell is selected is checked; otherwise, the message will not appear.

Error alerts

The purpose of a drop-down list of to select valid entries from a list. As a result, the chance of invalid data entry is significantly reduced. However, users can still enter text directly into the cell; therefore, invalid data entry is still possible.

The default message doesn’t provide any guidance regarding why the entry is invalid. But we can provide custom messages inside the Error Alert tab.

To provide a custom message, we only need to provide a title, an error message, and select a style icon.

Make sure show error alert after invalid data is entered is checked; otherwise, no error message will appear; a user could enter any value.

Useful notes

Before we move on, I want to make you aware of a few issues with data validation drop-down lists in Excel:

Identifying the cells containing data validation

The drop-down arrow is only visible when a user clicks on the cell. Therefore, here is no visual indicator that a cell contains a drop-down list exists until it is selected. Formatting the cell may be useful to provide a better user experience.

Copy and Paste dangers

When we copy and paste cells containing the data validation to other cells, the drop-down list is transferred as part of the format. This is great if we want to create a lot of drop-down lists containing the same items.

However… now for the danger part…

A user can copy and paste values into a cell, even if those values are not in the data validation list. If a user types into a cell, the data validation process runs; if a user pastes values into a cell, the validation is not triggered at all. This is a big problem

Here is another quirk…

If the worksheet is protected, the copy and paste overwrites the value, but retains the drop-down list. However, if the sheet is not protected, copy and paste applies the format from the source cell. As a result, the data validation drop-down list can disappear completely.

Highlight all cells with invalid options

Excel can perform a check to identify any cells containing values that do not meet the data validation criteria. Click Data > Data Validation (drop-down) > Circle Invalid Data

Data validation circles

This will highlight the cells as follows:

Data validation circle invalid data

To remove the circles, click Data > Data Validation (drop-down) > Clear Validation Circles.

Form control drop-down list

Form controls can be used as another type of drop-down list in Excel. While they remove some of the negatives from data validation drop-downs, they come with their own unique challenges. VBA can be used to control form control elements; however in this post, we’ll be keeping things simple and looking at the basic non-VBA functionality (which is still pretty powerful).

Let’s start by creating a form control drop-down list. These are contained within the Developer ribbon.

Click Developer > Insert > Combo Box (Form Control)

Developer - Insert Form Control Drop-Down

The mouse pointer will change to a cross. Click and hold the mouse while you draw the location to place the drop-down list. Holding the ALT key while placing the object will also snap the drop-down to the grid.

Right-click on the drop-down list and select format control…

Right-click Form Control for options

The format object window will open. Click on the control tab. The key fields are:

  • Input range – the range of cells to include in the drop-down list.
  • Cell link – the cell in which to output the value.
Format Object - Options

The cell selected for the cell link shows the chosen position in the drop-down box. As East is the third item in the list, cell F2 displays 3.

Linked cell show index of select item

The biggest issue with the form control drop-down is that the cell link shows the position in the drop-down rather than the value itself. By using the INDEX function and the input range cells, we can retrieve the value from the list.

INDEX function to display result as text

The formula in cell G2 is:

=INDEX(A2:A6,F2)

Input range options

With Form Control drop-down lists, the input range can be a standard cell range or a named range. Hardcoded lists and dynamic arrays are not compatible. However, we can use a dynamic array placed inside a named range as a workaround.

Useful notes

If we wish to have lots of drop-down lists, we can copy and paste a form control object. However, we must go into each drop-down individually to repoint to a new cell link.

We cannot enter text into the drop-down list; therefore, it is not possible to select an invalid entry.

Form controls are not compatible with Excel Online.

ActiveX drop-down list

Now for the final type of drop-down list in Excel; ActiveX drop-down list.

Click Developer > Insert > Combo Box (ActiveX Control)

Insert ActiveX Drop-Down

Just like the form control option shown above, draw the drop-down box on the worksheet.

Right-click on the drop-down and select properties from the menu.

ActiveX Drop-Down Properties

The properties dialog box opens. The critical parameters for our purposes are LinkedCell and ListFillRange. These are similar to the form control drop-down list; enter equivalent ranges into these fields. Click on the [x] in the top right corner to close the Properties window.

VBA Properties for ActiveX drop-down

Clicking Developer > Design Mode toggles between using and editing the drop-down list. When in design mode, the drop-down can be edited, but not used. Vice versa, when in display mode, the drop-down can be used, but not edited.

Developer - Design Mode

Unlike the form control version, the ActiveX drop-down displays the selected value directly in the linked cell.

ActiveX inserts value into a cell

ActiveX has more extensive formatting options than form controls.

Useful notes

ActiveX drop-down boxes have many features to be aware of:

  • When in design mode, the ActiveX drop-down can be copied or deleted, but not when in display mode.
  • ActiveX doesn’t work on a Mac or Excel Online. So, if you want a genuinely cross-platform workbook, this is not the option for you.

Which option to choose?

So, which option should you choose for a drop-down list in Excel? As I said in the introduction, it depends. My general advice is:

  1. Avoid ActiveX, if possible.
  2. Use Form Controls for single-cell selections where strict input is required.
  3. Use Data Validation, where a drop-down may need to be copied.

That’s just a basic rule I use. In all cases, suitable worksheet protection needs to be applied to prevent accidental changes. Ultimately, you’ll need to experiment with all the options and work out what is best for your circumstances.

About the author

Hey, I’m Mark, and I run Excel Off The Grid.

My parents tell me that at the age of 7 I declared I was going to become a qualified accountant. I was either psychic or had no imagination, as that is exactly what happened. However, it wasn't until I was 35 that my journey really began.

In 2015, I started a new job, for which I was regularly working after 10pm. As a result, I rarely saw my children during the week. So, I started searching for the secrets to automating Excel. I discovered that by building a small number of simple tools, I could combine them together in different ways to automate nearly all my regular tasks. This meant I could work less hours (and I got pay raises!). Today, I teach these techniques to other professionals in our training program so they too can spend less time at work (and more time with their children and doing the things they love).


Do you need help adapting this post to your needs?

I'm guessing the examples in this post don't exactly match your situation. We all use Excel differently, so it's impossible to write a post that will meet everybody's needs. By taking the time to understand the techniques and principles in this post (and elsewhere on this site), you should be able to adapt it to your needs.

But, if you're still struggling you should:

  1. Read other blogs, or watch YouTube videos on the same topic. You will benefit much more by discovering your own solutions.
  2. Ask the 'Excel Ninja' in your office. It's amazing what things other people know.
  3. Ask a question in a forum like Mr Excel, or the Microsoft Answers Community. Remember, the people on these forums are generally giving their time for free. So take care to craft your question, make sure it's clear and concise.  List all the things you've tried, and provide screenshots, code segments and example workbooks.
  4. Use Excel Rescue, who are my consultancy partner. They help by providing solutions to smaller Excel problems.
