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

private Microsoft.Office.Tools.Word.DropDownListContentControl dropDownListControl1;

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

    dropDownListControl1 = this.Controls.AddDropDownListContentControl("dropDownListControl1");
    dropDownListControl1.DropDownListEntries.Add("Monday", "Monday", 0);
    dropDownListControl1.DropDownListEntries.Add("Tuesday", "Tuesday", 1);
    dropDownListControl1.DropDownListEntries.Add("Wednesday", "Wednesday", 2);
    dropDownListControl1.PlaceholderText = "Choose a day";
}

Dim dropDownListControl1 As Microsoft.Office.Tools.Word.DropDownListContentControl

Private Sub AddDropDownListControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Select()
    dropDownListControl1 = Me.Controls.AddDropDownListContentControl("dropDownListControl1")
    With dropDownListControl1
        .DropDownListEntries.Add("Monday", "Monday", 0)
        .DropDownListEntries.Add("Tuesday", "Tuesday", 1)
        .DropDownListEntries.Add("Wednesday", "Wednesday", 2)
        .PlaceholderText = "Choose a day"
    End With
End Sub

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 AddDropDownListControlAtSelection method from the ThisAddIn_Startup method.

private Microsoft.Office.Tools.Word.DropDownListContentControl dropDownListControl1;

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

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

    dropDownListControl1 = vstoDoc.Controls.AddDropDownListContentControl("dropDownListControl1");
    dropDownListControl1.DropDownListEntries.Add("Monday", "Monday", 0);
    dropDownListControl1.DropDownListEntries.Add("Tuesday", "Tuesday", 1);
    dropDownListControl1.DropDownListEntries.Add("Wednesday", "Wednesday", 2);
    dropDownListControl1.PlaceholderText = "Choose a day";
}

Dim dropDownListControl1 As Microsoft.Office.Tools.Word.DropDownListContentControl

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

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Select()
    dropDownListControl1 = vstoDoc.Controls.AddDropDownListContentControl("dropDownListControl1")
    With dropDownListControl1
        .DropDownListEntries.Add("Monday", "Monday", 0)
        .DropDownListEntries.Add("Tuesday", "Tuesday", 1)
        .DropDownListEntries.Add("Wednesday", "Wednesday", 2)
        .PlaceholderText = "Choose a day"
    End With
End Sub
