Hi All,

我有3个下拉列表具有以下数据格式的列表。

Dropdown-1 下拉-2 下拉-3- -------------- -------------- --------------- $ Parent-1 男孩-1 Girl-1 Parent-2 男孩-2 Girl-2 Parent-3 男孩-3 Girl-3

Dropdown-1 Dropdown-2 Dropdown-3 -------------- -------------- --------------- Parent-1 Boy-1 Girl-1 Parent-2 Boy-2 Girl-2 Parent-3 Boy-3 Girl-3

根据下拉框中的选择;

Based on the selection from the dropdown boxes;

如果我选择 Parent-2来自Dropdown-1 男孩1来自Dropdown-2 Girl-2来自Dropdown-3

If I select Parent-2 from Dropdown-1 Boy-1 from Dropdown-2 Girl-2 from Dropdown-3

然后我需要以下结果 hierarchical 格式：

Parent 1 男孩1 名称1： 年龄1： 女孩1 名称1： 年龄1： 女孩2 名称2： 年龄2： 家长2 Boy 1 姓名1： 1岁： Girl 1 姓名1： 1岁： Girl 2 姓名2： 年龄2：
