That sounds like the regular behavior of NSPopUpButton: after clicking to pop
up the menu, you can type-select items from it.

I was going to suggest the same thing. NSPopUpButton should do what you want.

Typing to select from NSPopUpButton works OK for short lists. I just made a

popup with 300 items and it's already awkward. 10K would be absurd.

It also
has a NSPopUpButton on the side to use as an additional option (handy for short

Yes, exactly. When you have 20K customer records, you don't remember how
each was entered, or how spelled. You may need to type a letter or 2 and then
