I am looking for a box where a user can enter text or select
from the dropdown list.
In other words, a combining of input type=“text”
and select options.
Is there a way to do this in ColdFusion, Java, or html?
It's actually called a combobox and is generally used in
desktop apps, not on the web. However, activSoftware has a combobox
tag for CF that you can try.
