You can't show a data validation list in the standard data form.
If you can use add-ins, you could try John Walkenbach's Enhanced Data

list of items.

I have a drop-down menu containing the months of the year in my
spreadsheet. I want to train people to enter data using the data entry
form (Data -- Form). Is there any way to make this drop-down menu
appear in the data entry form?
