1、使用LISTBOX插件，选中后回车录入
维护好数据，并新增一个activeX列表框插件

Private Sub Worksheet_SelectionChange(ByVal Target As Range)If Target.Count > 1 Then Exit SubIf Target.Row >= 2 And Target.Row <= 10 And Target.Column = 2 Then '选择操作范围With ListBox1.MultiSelect = 1 '多选模式.ListStyle = 1.List = ActiveSheet.Range("F1:F7").Value.Top = Target.Top.Left = Target.Left + Target.Width.Height = Target.Height * 5.Width = 90.Visible = TrueEnd WithElseListBox1.ClearListBox1.Visible = FalseEnd If
End Sub' 双击切换选中状态
Private Sub ListBox1_DblClick(ByVal Cancel As MSForms.ReturnBoolean)Dim clickedIndex As IntegerclickedIndex = ListBox1.ListIndex ' 获取双击的选项索引If clickedIndex >= 0 Then ' 确保双击的是有效选项' 切换选中状态ListBox1.Selected(clickedIndex) = Not ListBox1.Selected(clickedIndex)End If
End Sub' 回车键录入 Excel 单元格
Private Sub ListBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)If KeyCode = vbKeyReturn ThenDim selectedItems As StringDim i As IntegerselectedItems = ""'遍历选中的项目For i = 0 To ListBox1.ListCount - 1If ListBox1.Selected(i) ThenIf selectedItems = "" ThenselectedItems = ListBox1.List(i)ElseselectedItems = selectedItems & ", " & ListBox1.List(i)End IfEnd IfNext iActiveCell.Value = selectedItemsEnd If
End Sub

效果

2、使用有效性的序列 +VBA。
正常情况下有效性的序列只能选择一个选项，参照excel表格设置下拉框选项并具有多选功能
设置好序列的内容，直接复制代码就能用了
唯一点就是多选时不能同时多选，要一个一个选上去。
