Create conditional drop-down lists

You have a misstype in the data validation for City. one have to select cell C2, not "Select Cell C1" as you said.

Any link to download the file?

Be Careful that Country or City names don't have spaces in them or else it wont work

Using an _ instead of a space fixes it

Nice tip.

I would enhance it so that if country changes, then the corresponding city field should be set to "* TBD"  [otherwise the old city is out of sync with the new country].  Do the same thing if the city changes.  I would then conditionally format the cells to highlight the "* TBD" cells.

In the code below, the names "Country", "City" and "Street" refer to cells B2:B4, C2:C4 and D2:D4, respectively.

Private Sub Worksheet_Change(ByVal Target As Range)

   Dim r               As Long

   Dim c               As Long

   Dim Cell            As Range

   Dim rngCountry      As Range

   Dim rngCity         As Range

   Dim rngStreet       As Range

   Set rngCountry = Range("Country")

   Set rngCity = Range("City")

   Set rngStreet = Range("Street")

   For Each Cell In Target.Cells

       r = 0

       c = 0

       If Not Intersect(Cell, rngCountry) Is Nothing Then

           r = Cell.Row

           c = rngCity.Column

       ElseIf Not Intersect(Cell, rngCity) Is Nothing Then

           r = Cell.Row

           c = rngStreet.Column

       End If

       If r <> 0 And c <> 0 Then

           ' clear dependent cell

           Cells(r, c).Value = "* TBD"

       End If

   Next Cell

End Sub

its a nice tip,

i created with other test name...i have a pax filtration of adult,child&infant. i need to display date of birth in col C2, if i select infant in B2.it worked, after selecting infant and 'date of birth' in c2, i need to change b2 as 'adult' for which i do not have any optional selection in c2.  the earlier selection of date of birth is not disappearing...

(selections are only 'date of birth' for c2)

could u revert pls

"I would enhance it so that if country changes, then the corresponding city field should be set to "* TBD"  [otherwise the old city is out of sync with the new country].  Do the same thing if the city changes.  I would then conditionally format the cells to highlight the "* TBD" cells."

Better would be to use the first value in each list, so that the user doesn't have to select something 100% of the time. The user would obviously be aware that he/she can make other choices from the drop downs. This is not uncommon behavior in data entry forms.

A few more countries & cities can result in city name explosion. One solution would be to create a city/street table, sorted in ascending order by city. You can then create a lookup formula that selects only the street range for the appropriate city, thus eliminating all of the city names.

I'm not a fan of always defaulting a value to the first value in the list.  My philosophy for whether to default a value or not depends on a combination of:

1.  What are the chances that I can guess the value correctly?  If I can't guess it with a sufficiently high degree of confidence, then I don't default it to anything.  For example, if one option is used 10% of the time and all the others are only used 5%, the "big" option isn't "big" enough for me to default to it.

2.  What's the risk if the user doesn't notice that the value has been defaulted and blindly accepts my default?  If this process was to delete information for a city, I wouldn't want to risk that the user blindly accepts my default city.

Its nice being a member of this group. Because I found it so interesting learning on line. especially on Microsoft excel.

thanks regards

Can you provide a link to the example so that we can see it in action.

Thanks

Hi there,

this can be actually done totally dynamically. I mean that it's not necessary to create named ranges for every set of values so that you can freely add new values and they are automatically considered in the validation. It can be also combined with an array function retrieving distinct values from a 'raw' list so that you can feed your validation list from basically any source of data.

The validation formula is then of course a bit more complicated but it works perfectly.

I'd send a sample file but I don't know where.

Below is how the validation works but without the excel it's not very understandable.

Validations:

Practice

=CCsHeader

CC

"=OFFSET(CCsData;0;MATCH(I26;CCsHeader;0)-1;

  COUNTA(OFFSET(CCsData;0;MATCH(I26;CCsHeader;0)-1;

  14;1));1)"

"What does it do:

- takes value in cell I26 (the practice for which we are creating list of CCs) and finds it's position in the CCsHeader (the first MATCH function)

- creates a range of the CCs under the selected practice (Microsoft in our case) (the outter OFFSET function)

- the inner COUNTA function (and everything inside) counts number of CCs under the selected practice. It's pretty the same as the stuff before that but we need to limit the area where to count the values (max. 14 values in our case but it can also be e.g. whole column)."

Name

"=OFFSET(NamesData;0;MATCH(J26;NamesHeader;0)-1;

COUNTA(OFFSET(NamesData;0;MATCH(J26;NamesHeader;0)-1;

13;1));1)"

"What does it do:

Exactly the same thing as the CC validation except that it looks for range of Names under the CC selected in cell J26"

Hi!

I can not proceed following:

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)

Unknown valus but not question if I want continue.

Any idea why?

Dear jirina42

Can u show the table and one formula somehow?

BR

Add the following EVENT to your workbook, when you change your second option (2nd data validation option), the 1st option will dissapear.

eg. when you selected the wrong city 1st time, you

re-select again, the country will appear blank immediately. That means you need to re-select again the correct country based on the re-selected city.

rgds,

I can get this to work great without using an underscore or period, but entering anything other than a single value and the drop-down box fails to open??

Any Help?

indirect work well with drop down. however,it is not working with combo box. any one can help me how to use indirect in combo box
