NSTextField with suggestions drop-down

Question

Instead of implementing my own, I am looking into reusing an existing custom NSTextField that has support for suggestions drop-down - Same as the one in the browser as you type you get a list of suggestions underneath.

Do you know any good ones?

Thank you!

They're called completions. You still use a regular text field but add this:

control:textView:completions:forPartialWordRange:indexOfSelectedItem

The biggest problem is you need to provide the list of words that can be autocompleted.
