Ash Chip said, Data Validation dropdown lists don't support
autocomplete. If you can use programming, there are instructions here
for adding a combobox from which you can select one of the values from
the data validation list. In the combobox, you can enable autocomplete:

Is it possible to have a validation drop-down jump through the list as a user
keys in text? For example, for a list of items: Apple, Bamboo, Cat, and Dog
if the user keys C, it automatically jumps to Cat. We have a drop-down with
about 1500 text values and it gets a bit tedious scrolling down every time.
Thanks in advance.
