Overall lgtm

I was a little on the fence about explicitly moving logic out of the template back into the user side (for options, selected states). The initial idea for templates was to require minimal user input, and let a user track the internal state via informational callbacks but not have to be responsible for directly managing it. But that said, typeahead is a pretty complex use case for select with a wide variety of applications and requirements, and a user is probably tracking both states already, so maybe some additional necessary user-side code is inevitable and helpful.
