Creating Drop-down menus with subset drop-down menus

[Benjamin]

I'm creating an excel sheet with drop-down menus using validations. I'd like
to create a second row that looks up a list of equipment types from the first
row's selection. i.e. column 1 = pumps, electrical, vessels.
column 2 = types of pumps,
or types of electrical
or types of vessels.
Is there a way to do this with formulas
or if not how do I do it with code?

Debra Dalgleish's web site has exactly what you're looking for.

It's called a "Dependent List":

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)

I need to do this for 300-2000+ fields. Each with the same Parent Categories
and Child Categories?
Will I be able to copy and paste or fill the fields?

I need to do this for about 2000+ entries....
Can I copy and paste the formula down the column?
opening the validation box isn't practical for this many.
