Excel data validation with suggestions/autocomplete

Question

Apologies for my low level of Excel understanding, maybe what I am looking to do is not possible.

I have a list of 120 entries that I want to use as data validatio

Answer 1

There's a messy workaround at http://www.ozgrid.com/Excel/autocomplete-validation.htm that basically works like this:

1. Enable "Autocomplete for Cell Values" on Tools - Options > Edit;
2. Recreate the list of valid items on the cell immediately above the one with the validation criteria;
3. Hide the lines with the list of valid items.
