I am developing some HTML for a program which uses Chromium Embedded Framework (CEF), specifically CefSharp.

The exact functionality I want is already perfectly handled with use of datalist elements: an input where the user can freetype and enter any value, but as they type suggestions from a list of expected values can easily be selected to autofill.

However, it appears that datalist is not supported.

I am wondering if it would be possible to emulate the behavior of a datalist linked input using JavaScript? The select tag isn’t appropriate for this case because free-typing new values will be just as common as selecting a pre-existing value.
