您可以使用e.stopPropagation()

这将防止关闭任何下拉菜单":

This will prevent close of any 'dropdown-menu':

$('.dropdown-menu').on('click', function (e) {
    e.stopPropagation();
})

如果只需要特定的下拉菜单，则可以相应地更改jQuery选择器$('.dropdown-menu').

If you want only a specific dropdown you'd change the jQuery selector $('.dropdown-menu') accordingly.

这是一个可行的示例
