Option Explicit

Sub Worksheet_Change(ByVal Target As Range)
\'让数据有效性选择 可以多选,重复选
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 = 11 Then \'这里规定好哪一列的数据有效性是多选的，A列是第1列，依次类推，如3就是C列，7就是G列
    If oldVal = "" Then
      \'do nothing
      Else
      If newVal = "" Then
      \'do nothing
      Else
        If InStr(1, oldVal, newVal) <> 0 Then  \'重复选择视同删除
          If InStr(1, oldVal, newVal) + Len(newVal) - 1 = Len(oldVal) Then \'最后一个选项重复
            Target.Value = Left(oldVal, Len(oldVal) - Len(newVal) - 1)
          Else
            Target.Value = Replace(oldVal, newVal & ",", "") \'不是最后一个选项重复的时候处理逗号
          End If
        Else \'不是重复选项就视同增加选项
        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
End If

exitHandler:
Application.EnableEvents = True
End Sub
