What I’ve heard:
Autocomplete
Autosuggest(ion)
Combo box
Search (suggestion) box
My thoughts:
1. “Search” is implied (it’s happening in real time)
2. “Combo” is ambiguous jargon
3. “Auto” is helpful
4. “Complete” and ”suggest” are interchangeable
“Autocomplete” is most common. But that’s an actual HTML attribute, so I don’t like it here.
Autosuggest is my preference. WITH single-select or multi-select as an important qualifier.
