[autocomplete] render list of items as empty result

[pondorasti]

Feature request

Summary

I'm building a command palette using <Autocomplete>, and I would like to be able to render some default list items when there's no search results. The key point is that I still want to render the Empty children as a List with Items so I can keep all the interactivity.

Default	No search results

Motivation

Maybe it's not the most popular pattern, but there are a handful of real world examples like this. For reference, here's Raycast showing a list of default results when there's no match.

This is supported if you control the filtering externally: https://codesandbox.io/p/sandbox/wonderful-hellman-gqpqd9

For uncontrolled usage, a separate prop like emptyItems would probably be necessary

ooo, thanks!

is the useFilter/controlled way undocumented? I swear a looked for this and couldn't find any references at the time of writing this issue.

agreed, that would be very nice.

Small suggestion, the docs would be much nicer if you push examples above API reference

Combobox has the hook documented, but Autocomplete is missing an API reference to it, outside of the async search demo. Agree it should be there as well
