Need to figure out how to create drop down list in Powerpoint using developer option

Bridget Shoulders 0

I've watched the few videos and read articles I can find on this topic but still cannot figure out how to create a drop down list in powerpoint, using developer option. When I get to the point of entering my data in the code field:

End Sub

ComboBox1.AddItem "Problem"

ComboBox1.AddItem "Acute Respiratory Failure"

ComboBox1.AddItem "Cardiogenic Shock"

ComboBox1.AddItem "Pneumonia"

ComboBox1.AddItem "Hypovolemic Shock"

ComboBox.ListRows = 5

End Sub

Once saved, I get a message "compile error: invalid outside procedure" I'm not a coder or programmer and have never done this before (able to do without a problem in Word). Most of the information available assumes everybody knows how to do this and seems like basic steps are left out. Please help!

Hi @Bridget Shoulders ,

The error "Compile error: Invalid outside procedure" occurs because the code you pasted is not enclosed within a valid procedure block (a Sub or Function). You also have an extra End Sub at the very beginning of your code. In VBA, any executable code (like adding items to a ComboBox) must live inside a procedure.

Additionally, near the bottom of your code, you refer to ComboBox.ListRows = 5 lacking the 1 — it should be ComboBox1 to match the rest of the lines.

To fix your issue, clear out your old code and replace it with a properly formulated Subroutine.

For example, if you place the code within the module for the slide containing the ComboBox (e.g., double-clicking the ComboBox in Developer Mode will usually take you there), you can use the DropButtonClick event to populate the list the moment you try to open the dropdown in Slide Show mode:

Private Sub ComboBox1_DropButtonClick()
    ' Ensure the list hasn't already been populated to prevent duplicates
    If ComboBox1.ListCount = 0 Then
        ComboBox1.AddItem "Problem"
        ComboBox1.AddItem "Acute Respiratory Failure"
        ComboBox1.AddItem "Cardiogenic Shock"
        ComboBox1.AddItem "Pneumonia"
        ComboBox1.AddItem "Hypovolemic Shock"

        ' Fixed typing error: ComboBox -> ComboBox1
        ComboBox1.ListRows = 5
    End If
End Sub

Alternatively, if you just want to run a macro manually to populate the dropdown once while designing, you can use:

Sub PopulateComboBox()
    ComboBox1.Clear ' clear any old items

    ComboBox1.AddItem "Problem"
    ComboBox1.AddItem "Acute Respiratory Failure"
    ComboBox1.AddItem "Cardiogenic Shock"
    ComboBox1.AddItem "Pneumonia"
    ComboBox1.AddItem "Hypovolemic Shock"

    ComboBox1.ListRows = 5
End Sub

To run this manual setup, just click anywhere inside the Sub PopulateComboBox() and press F5 or click the green "Run" arrow in the VBA Editor toolbar.

If you found my response helpful or informative, I would greatly appreciate it if you could follow this guidance or provide feedback.

Thank you.

Thank you so much for your response. I made the changes and was able to view the drop-down box in PowerPoint presentation mode. When I clicked on the slide, it opened in another window, I’m assuming that’s how it’s supposed to work, right?

My plan was to include 2 drop down list boxes in one slide (2 separate responses to answer a 2-part question). I was able to add the 2 boxes, using the MS Forms 2.0 combo box in developer option. After opening VBA editor, I entered the following data into the code window:

Private Sub ComboBox1_DropButtonClick()

        ComboBox1.AddItem "Acute Respiratory Failure"

        ComboBox1.AddItem "Cardiogenic Shock"

        ComboBox1.AddItem "Pneumonia"

        ComboBox1.AddItem "Hypovolemic Shock"

        ComboBox1.ListRows = 4

End Sub

Private Sub ComboBox2_DropButtonClick()

        ComboBox2.AddItem "Poor oxygenation"

        ComboBox2.AddItem "Renal losses"

        ComboBox2.AddItem "GI bleeding"

        ComboBox2.AddItem "Tachycardia"

        ComboBox2.ListRows = 4

End Sub

I had to clear the information that was initially entered with first attempt, before adding above info. I did not get an error message, but when I tried to view in presentation mode, nothing was in the drop-down boxes. I returned to VBA editor, and the original code data (that I had cleared) was still there. I tried to figure this out with an on online search, tried to remove it but the option to remove was greyed out.

From what I read, I should have written the code inside a slide object module versus a standard module (since I only want to use the code for an individual slide). If this is the case, I’m not clear if I can make the changes in my current presentation. Again, this is all new to me, and most of the information available was in an AI summary (with a lot of information in the summary but not in the referenced material) so not sure of the accuracy. I would appreciate any assistance you can provide. And is there a detailed instructional resource available you can refer me to? Thanks in advance for your help.

Hi @Bridget Shoulders ,

The reason your dropdowns were empty in presentation mode is likely that the code was placed in a general "Standard Module" rather than attached directly to the slide itself.

Here is how to get both dropdowns working:

1. Removing the Old Code If that old cleared code won't go away, it's likely stuck in a Standard Module.

Open the VBA Editor (Developer tab -> Visual Basic).

On the left side, look for the Project pane. (Press Ctrl + R if you don't see it).

Expand the Modules folder. You will likely see Module1.

Right-click Module1, choose Remove Module1..., and click No when asked to export. This deletes the old code.

2. Putting Code on the Correct Slide To ensure the code connects to the specific drop-downs on your slide:

Return to your PowerPoint slide in Normal (Edit) View.

Double-click the first dropdown box directly on the slide. This automatically opens the VBA editor exactly where you need to be (a slide module, usually named like Slide1).

Delete the auto-generated line that says Private Sub ComboBox1_Change().

Paste the updated code below into the window.

3. The Updated Code (added ComboBox.Clear so the list doesn't duplicate itself every time it's clicked)

Private Sub ComboBox1_DropButtonClick() ComboBox1.Clear ComboBox1.AddItem "Acute Respiratory Failure" ComboBox1.AddItem "Cardiogenic Shock" ComboBox1.AddItem "Pneumonia" ComboBox1.AddItem "Hypovolemic Shock" ComboBox1.ListRows = 4 End Sub Private Sub ComboBox2_DropButtonClick() ComboBox2.Clear ComboBox2.AddItem "Poor oxygenation" ComboBox2.AddItem "Renal losses" ComboBox2.AddItem "GI bleeding" ComboBox2.AddItem "Tachycardia" ComboBox2.ListRows = 4 End Sub

Regarding the Code Window Opening When playing the presentation in Slide Show Mode, clicking the drop-down will only show the list. Double-clicking it during Normal (Edit) view opens the VBA editor so you can program it—this is totally normal behavior while designing!

Resources Because PowerPoint VBA dropdowns share logic with Excel VBA ComboBoxes, the programming concepts are very similar. Here are some official Microsoft documentation links to help you understand how ComboBoxes work in VBA:

ComboBox control | Microsoft Learn

DropDown method example | Microsoft Learn

Hope this gets it working for you.

Hi @Bridget Shoulders , just checking in. Do you have any update on this post?

I had already followed the directions you provided to remove the old code in the Standard Module, but unable because the option to remove is greyed out. I tried again with the same results. Is there any way to activate the remove option, so I can remove the code?

Thanks

Hi @Bridget Shoulders ,

If the Remove option is greyed out, it usually means one of two things in the VBA Editor:

1. You are trying to remove a Slide Object Module (like Slide1) PowerPoint will not allow you to delete a Slide module because they are permanently attached to the physical slides in your presentation. If the old code is in here:

You don't need to delete the module itself. Double-click the module to open the code window, press Ctrl + A to select all the text inside, and press the Delete key on your keyboard. Once the window is clean and empty, the code is gone and won't interfere.

2. The code is currently running or paused (Break Mode) If you are definitely right-clicking a Standard Module (like Module1) and "Remove" is greyed out, the VBA editor likely thinks the code is still running in the background.

Look at the toolbar at the very top of the VBA Editor window and click the Reset button (it looks like a small blue square "Stop" button). Once you stop the code editor, you should be able to right-click Module1 and select Remove.

Try clicking the Reset (Stop) button, or just completely clearing the text out of the window if it's a Slide module. Let me know if that clears it up!
