Custom Validation - Dependent Drop Down Lists
- by Holysmoke
Hi,
I've two columns in a sheet that are interdependent and I want to use validation, drop-down lists, on both as follows:
Column A (TYPE) | Column B (Sub-TYPE)
------------------------------------------|
TypeA, TypeB | If TypeA SubTypeA1, |
... TypeN | SubTypeA2 ... SubTypeAN |
------------------------------------------|
Creating the column A drop down is trivial. How do I create the Column B drop down, that in turn depends on what was chosen in Column A?
TIA
