excel下拉多选

Excel下拉框一般只能单选，但有时候需要多选，多选的方法如下：

以office 2016中的excel为例：
1、数据验证入口

 

2、设置数据

3、sheet页右击查看代码

 

 4、复制下面代码进去：

源码地址: Excel Data Validation Drop Down Select Multiple Items (contextures.com)

Private Sub Worksheet_Change(ByVal Target As Range)
' Developed by Contextures Inc.
' www.contextures.com
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
If Target.Count > 1 Then GoTo exitHandler

On Error Resume Next
Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitHandler

If rngDV Is Nothing Then GoTo exitHandler

If Intersect(Target, rngDV) Is Nothing Then
   'do nothing
Else
  Application.EnableEvents = False
  newVal = Target.Value
  Application.Undo
  oldVal = Target.Value
  Target.Value = newVal
  If Target.Column = 3 Then
    If oldVal = "" Then
      'do nothing
      Else
      If newVal = "" Then
      'do nothing
      Else
      Target.Value = oldVal _
        & ", " & newVal
'      NOTE: you can use a line break,
'      instead of a comma
'      Target.Value = oldVal _
'        & Chr(10) & newVal
      End If
    End If
  End If
End If

exitHandler:
  Application.EnableEvents = True
End Sub

5、效果如下：
