Selective Validation

W

WildWill

I have a cell (in column A) that may either contain a value of "1", "2" or
"3". These values are contained in a validation list and appear in a
drop-down box when clicking on the cell. I want the selection of the specific
value for the cell in column A to trigger a second drop down list for column
B. I.e. If the user clicks on the cell in column A and selects value "2" from
the drop down list, then the moment that "2" is input into that cell, a
second drop down menu appears in the adjacent cell in column B, containing
the options "A", "B" or "C" for the user to choose from, alternatively if the
user selected "3" as the value for the cell in column A, then the drop down
box for the cell in column B will contain the options of "D", "E" or "F", and
so on. Isthis possible?

Hi,


Here are the steps for creating a dynamic data validation list:

1. Create three or more list in the spreadsheet. For example:
A B C
New York Quebec Canada
Seattle Toronto US
Miami Victoria

You would name lists: US (A1:A3), Canada (B1:B3), Countries (C1:C2) this
last is optional

2. Select the cell where you want the initial validation list, for this
example, D1
3. Choose Data, Validation
4. From the Allow drop-down and choose List
5. In the Source box enter the following formula
=Countries
6. Move to the location where you want the dynamic (changing) list to
appear, say for example E1
7. Choose Data, Validation, List and in the Source box enter the formula
=INDIRECT(D1)
