Text area auto complete for multiple items without a token

I want to have a textarea that auto complete from the collection but without using a token

Is that possible ?

so that the user whenever he types a letter it suggests from the collection and let him add multiple not just one.

Thanks in advance,
Nader Ikladious.

The issue names no files, tests, or entry points. Start by reading the existing autocomplete behavior for collection suggestions, tokens, and multiple selections, then determine whether textarea input is supported. Done means suggestions appear as the user types without a token and multiple collection items can be added.
