Question

需要知道是否可以在Excel中创建多选下拉列表，然后动态链接到另一个多选下拉列表。

例如，考虑两列，即国家和城市，如下所示

India -> Delhi, Mumbai, Bangalore;
Australia -> Sydney, Hobart, Brisbane, Perth;
USA -> CA, NYC, LA;
Pakistan -> Lahore, Karachi, Peshawar

如果我在第一次下拉菜单中选择印度和澳大利亚，我应该可以选择在德里，孟买，班加罗尔，悉尼，霍巴特，布里斯班和珀斯选择一个或多个选项。

编辑：我已经能够创建一个多选下拉列表和一个选择下拉列表，根据父列中选择的单个值动态更新。我无法将两者结合起来
