Create conditional drop-down lists

In Excel 2007 (and earlier), it’s possible to create a drop-down list. By using the INDIRECT function, you can then create additional drop-down lists that are conditional to the first drop-down list.

In this example we’ll create the following table:

	A	B	C	D
1		Country	City	Street
2	David	Netherlands	Rotterdam	Abraham van Stolkweg
3	Linda	Germany	Munich	MunichStreet1
4	Peter	Britain	London	Bacon Street (E1)

Columns B, C, and D contain drop-down lists. If you select Netherlands in the drop-down list in column B, only Dutch cities will be displayed in the drop-down list in Column C. If you select Germany, only German cities will be displayed in the drop-down list in Column C. Similarly, when you select a city in Column C, only the street names of that city will be displayed in column D.

To create conditional lists, complete the following procedures.

Enter the data

First, we’ll create the table as shown below.

Now, we’ll create a few lists.

First, we’ll create a list of countries. In this example, we create the following countries:

• In Cell F1, type Netherlands.
• In Cell G1, type Britain.
• In Cell H1, type Germany.

As you can see I made a horizontal list instead of a vertical list. This isn’t really necessary, but it is easier to maintain to keep the cities under the right country.

Second, we’ll add three cities to pick from for each country.

Cell F2: Amsterdam	Cell G2: London	Cell H2: Bonn
Cell F3: Rotterdam	Cell G3: Canterbury	Cell H3: Berlin
Cell F4: Eindhoven	Cell G4: Manchester	Cell H4: Munich

Now, we’ll create a list of streets for each city. In the example, you can then choose from two streets per city.

Cell F8: AmsterdamStreet1	Cell G8: LondonStreet1	Cell H8: BonnStreet1
Cell F9: AmsterdamStreet2	Cell G9: LondonStreet2	Cell H9: BonnStreet2
Cell F11: RotterdamStreet1	Cell G11: CanterburyStreet1	Cell H11: BerlinStreet1
Cell F12: RotterdamStreet2	Cell G12: CanterburyStreet2	Cell H12: BerlinStreet2
Cell F14: EindhovenStreet1	Cell G14: ManchesterStreet1	Cell H14: MunichStreet1
Cell F15: EindhovenStreet2	Cell G15: ManchesterStreet2	Cell H15: MunichStreet2

The worksheet should look like this now:

Define the names

Ok, all content is provided. Now we can start creating a name for each range.

• Select the cells F2:F4 and name the range: Netherlands
• Select the cells G2:G4 and name the range: Britain
• Select the cells H2:H4 and name the range: Germany
  
• Select the cells F7:F8 and name the range: Amsterdam
• Select the cells F10:F11 and name the range: Rotterdam
• Select the cells F13:F14 and name the range: Eindhoven
  
• Select the cells G7:G8 and name the range: London
• Select the cells G10:G11 and name the range: Canterbury
• Select the cells G13:G14 and name the range: Manchester
  
• Select the cells H7:H8 and name the range: Bonn
• Select the cells H10:H11 and name the range: Berlin
• Select the cells H13:H14 and name the range: Munich

For information about how to define names, see Define and use names in formulas.

Create the drop-down lists

After defining the names, we can create the drop-down lists.

First, we’ll make a drop-down list for Country.

1. Select cell B2.

2. On the ribbon, click the Data tab.

3. In the Data Tools group, click Data Validation.

4. Fill the values as follows:

   In the Allow box, select List.
   In the Source box, type =$F$1:$H$1



Note: Dollar signs ($) are used in the formula so that we can drag the cell downwards from David to Peter.

5. Click OK.

6. Drag the cell content downwards.

Now, we’ll make the first conditional drop-down list.

1. Select Cell C1.

2. On the ribbon, click the Data tab.

3. In the Data Tools group, click Data Validation.

4. Fill the values as follows:

     In the Allow box, select List.
   In the Source box, type =INDIRECT($B2)
      


Note: In the formula, a Dollar sign ($) is not placed before the row. That is because we want to drag the cell formula downwards.

5. Click OK.

Note: If you click OK, you may get an error message indication that the evaluation of the formula was an error. This is correct, because the cell where this list depends on (B2) is empty.

6. Drag the cell content downwards.

Now, we’ll make our second conditional drop-down list.

1. Select cell D2.

2. On the ribbon, click the Data tab.

3. In the Data Tools group, click Data Validation.

4. Fill the values as follows:

     In the Allow box, select List.
   In the Source box, type =INDIRECT($C2)
     


Note: In the formula, a Dollar sign ($) is not placed before the row. That is because we want to drag the cell formula downwards.

5. Click OK.

Note: If you click OK, you may get an error message indicating that the evaluation of the formula was an error. This is correct, because the cell on which this list depends (C2) is empty.

6. Drag the cell content downwards.

Done!
If you choose a country, the City field displays only cities for that country. And only streets for the selected city will be shown.
