To help users enter data in a spreadsheet, you can create drop down lists with Excel's Data Validation feature. For example, in an order form, you could provide drop down lists of customers, products, colours, sizes and shipping methods.

为了帮助用户在电子表格中输入数据，您可以使用Excel的“数据验证”功能创建下拉列表。 例如，在订单中，您可以提供客户，产品，颜色，尺寸和运输方式的下拉列表。

Usually, each of these lists would need a different Source in the Data Validation dialog box. The Customer list would have =CustList as its source, while the Product drop down would have =ProdList as its source.

通常，这些列表中的每个列表在“数据验证”对话框中都需要一个不同的“来源”。 客户列表将以= CustList作为其源，而产品下拉列表将以= ProdList作为其源。

使用相同的来源 (Use the Same Source)

Instead of using a different source for each data validation list, AlexJ has devised a simple way to use the same source for all the lists. This makes it much easier to create and maintain a set of drop down lists.

AlexJ没有为每个数据验证列表使用不同的来源，而是设计了一种简单的方法为所有列表使用相同的来源。 这使创建和维护一组下拉列表变得更加容易。

In AlexJ's sample file, he's recording farm information, with drop down lists for Fruit, Vegetable, Farm Equipment and Farmer. He's typed these lists in the workbook, and named them: DD.Fruit, DD.Veg, DD.Equip and noDD.

在AlexJ的样本文件中，他记录着农场信息，以及水果，蔬菜，农场设备和农夫的下拉列表。 他在工作簿中键入了这些列表，并将其命名为：DD.Fruit，DD.Veg，DD.Equip和noDD。

The noDD list is just a blank cell, and it can be used when you want users to be able to type freeform in a column.

noDD列表只是一个空白单元格，当您希望用户能够在列中键入自由格式时可以使用它。

In row 2, above the table where users will select from the drop down lists, AlexJ has typed the name of the source range for the column below.

在用户将要从下拉列表中选择的表上方的第2行中，AlexJ为以下列键入了源范围的名称。

Then, AlexJ selected all the blue cells, where drop down lists will be created. In the Data Validation dialog box, he selected Allow: List. As the Source, he entered: =INDIRECT(C$2)

然后，AlexJ选择了所有蓝色单元格，将在其中创建下拉列表。 在“数据验证”对话框中，他选择了“允许：列表”。 作为来源，他输入： = INDIRECT(C $ 2)

The column reference (C) is relative, and the row reference ($2) is absolute.

列引用(C)是相对的，行引用($ 2)是绝对的。

设定提示 (Setup Tips)

• AlexJ hides row 2, using Outlining, so users aren't distracted by the range names.AlexJ使用大纲隐藏第2行，因此用户不会被范围名称所分散。
• In the sample file, the named ranges are on the same sheet as the data entry range. In his actual files, AlexJ would have these on another sheet, hidden from users.在示例文件中，命名范围与数据输入范围在同一页上。 在他的实际文件中，AlexJ将这些文件放在另一张纸上，对用户隐藏。
• Instead of selecting noDD, cell F2 could be left blank, so no dropdown list would appear.代替选择noDD，单元格F2可以留为空白，因此不会出现下拉列表。
• No Error Alerts or Input Messages are used in the sample file, but you could add these to your application, if needed.示例文件中没有使用错误警报或输入消息，但是可以根据需要将它们添加到应用程序中。
• The drop down range names in cells J6:M6 are in a range named DD.Ranges. That range is used to create the drop down lists in row 2.单元格J6：M6中的下拉范围名称在一个名为DD.Ranges的范围内。 该范围用于在第2行中创建下拉列表。

你怎么看？ (What Do You Think?)

I frequently use the INDIRECT function to create dependent data validation lists. However, I hadn't seen this idea used before, to create different drop down lists from the same source formula. To me, it seems like a great way to create several adjacent lists, and makes it easy to maintain them.

我经常使用INDIRECT函数来创建相关的数据验证列表 。 但是，我以前从未见过使用同一想法从同一源公式创建不同的下拉列表的想法。 对我而言，这似乎是创建多个相邻列表并使其易于维护的好方法。
