This is a solution how to make autocomplete drop down list with VBA :

Firstly you need to insert a combo box into the worksheet and change its properties, and then running the VBA code to enable the autocomplete.

1. Get into the worksheet which contains the drop down list you want it to be autocompleted.

2. Before inserting the Combo box, you need to enable the Developer tab in the ribbon.

a). In Excel 2010 and 2013, click File > Options. And in the Options dialog box, click Customize Ribbon in the right pane, check the Developer box, then click the OK button.

b). In Outlook 2007, click Office button > Excel Options. In the Excel Options dialog box, click Popular in the right bar, then check the Show Developer tabin the Ribbon box, and finally click the OK button.

3. Then click Developer > Insert > Combo Box under ActiveX Controls.

4. Draw the combo box in current opened worksheet and right click it. Select Properties in the right-clicking menu.

5. Turn off the Design Mode with clicking Developer > Design Mode.

6. Right click on the current opened worksheet tab and click View Code.

7. Make sure that the current worksheet code editor is opened, and then copy and paste the below VBA code into it.

Code borrowed from extendoffice.com

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'Update by Extendoffice: 2018/9/21
    Dim xCombox As OLEObject
    Dim xStr As String
    Dim xWs As Worksheet
    Dim xArr



    Set xWs = Application.ActiveSheet
    On Error Resume Next
    Set xCombox = xWs.OLEObjects("TempCombo")
    With xCombox
        .ListFillRange = ""
        .LinkedCell = ""
        .Visible = False
    End With
    If Target.Validation.Type = 3 Then
        Target.Validation.InCellDropdown = False
        Cancel = True
        xStr = Target.Validation.Formula1
        xStr = Right(xStr, Len(xStr) - 1)
        If xStr = "" Then Exit Sub
        With xCombox
            .Visible = True
            .Left = Target.Left
            .Top = Target.Top
            .Width = Target.Width + 5
            .Height = Target.Height + 5
            .ListFillRange = xStr
            If .ListFillRange = "" Then
                xArr = Split(xStr, ",")
                Me.TempCombo.List = xArr
            End If
            .LinkedCell = Target.Address
        End With
        xCombox.Activate
        Me.TempCombo.DropDown
    End If
End Sub

Private Sub TempCombo_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
    Select Case KeyCode
        Case 9
            Application.ActiveCell.Offset(0, 1).Activate
        Case 13
            Application.ActiveCell.Offset(1, 0).Activate
    End Select
End Sub

9. Click File > Close and Return to Microsoft Excel to close the Microsoft Visual Basic for Application window.

10. Now, just click the cell with drop down list, you can see the drop-down list is displayed as a combo box, then type the first letter into the box, the corresponding word will be completed automatically.

Note: This VBA code is not applied to merged cells.
