This version is for a document-level customization. To use this code, paste it into the ThisDocument class in your project, and call the AddComboBoxControlAtRange method from the ThisDocument_Startup method.

Dim comboBoxControl2 As Microsoft.Office.Tools.Word.ComboBoxContentControl

Private Sub AddComboBoxControlAtRange()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    comboBoxControl2 = Me.Controls.AddComboBoxContentControl(Me.Paragraphs(1).Range, "comboBoxControl2")
    With comboBoxControl2
        .DropDownListEntries.Add("Red", "Red", 0)
        .DropDownListEntries.Add("Green", "Green", 1)
        .DropDownListEntries.Add("Blue", "Blue", 2)
        .PlaceholderText = "Choose a color, or enter your own" 
    End With 
End Sub

private Microsoft.Office.Tools.Word.ComboBoxContentControl comboBoxControl2;

private void AddComboBoxControlAtRange()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();

    comboBoxControl2 = this.Controls.AddComboBoxContentControl(this.Paragraphs[1].Range,
        "comboBoxControl2");
    comboBoxControl2.DropDownListEntries.Add("Red", "Red", 0);
    comboBoxControl2.DropDownListEntries.Add("Green", "Green", 1);
    comboBoxControl2.DropDownListEntries.Add("Blue", "Blue", 2);
    comboBoxControl2.PlaceholderText = "Choose a color, or enter your own";
}

This version is for an application-level add-in. To use this code, paste it into the ThisAddIn class in your project, and call the AddComboBoxControlAtRange method from the ThisAddIn_Startup method.

Private Sub AddComboBoxControlAtRange()
    If Me.Application.ActiveDocument Is Nothing Then 
        Return 
    End If 

    Dim vstoDoc As Document = Me.Application.ActiveDocument.GetVstoObject()
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    comboBoxControl2 = vstoDoc.Controls.AddComboBoxContentControl( _
        vstoDoc.Paragraphs(1).Range, "comboBoxControl2")
    With comboBoxControl2
        .DropDownListEntries.Add("Red", "Red", 0)
        .DropDownListEntries.Add("Green", "Green", 1)
        .DropDownListEntries.Add("Blue", "Blue", 2)
        .PlaceholderText = "Choose a color, or enter your own" 
    End With 
End Sub

private Microsoft.Office.Tools.Word.ComboBoxContentControl comboBoxControl2;

private void AddComboBoxControlAtRange()
{
    if (this.Application.ActiveDocument == null)
        return;

    Document vstoDoc = this.Application.ActiveDocument.GetVstoObject();
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();

    comboBoxControl2 = vstoDoc.Controls.AddComboBoxContentControl(
        vstoDoc.Paragraphs[1].Range,
