I'm trying to make a drop-down list in my spreadsheet, my spreadsheet has a couple of sheets but the main two sheets are "Master" and "Sheet3".
I have made the drop-down list using the Data -> Data validation as shown in the below screenshot:

And in the "Sheet3" sheet there is a big table (1000 columns) of data that I want to make a drop-down list from, from each column in it.
Now what I want is to drag copy this cell down so that the criteria will be like this:
- =Sheet3!A1:A
- =Sheet3!B1:B
- =Sheet3!C1:C
- =Sheet3!D1:D
- ...etc
and so forth for 1000 rows, but when I do this, it does not increment the column letter, it's just like the first cell criteria value (=Sheet3!A1:A) for all other rows.
Is there a way to make this work without me having to edit each row in this 1000-row column manually?
Thank you all.
