I agree they are great but isn't most of the work in fetching & sorting the data? I can't see how this would work as a general widget. In terms of the UI - I made a react component for showing dynamic suggestions (essentially a wrapper for downshift). And I've found the options out there for the sorting part quite good (e.g. match-sorter for sync or Elasticsearch completion suggester for async) https://dan-kwiat.github.io/filter-suggest/ https://dan-kwiat.github.io/filter-suggest/
