Just wanted to share a package I have been working on. React is my main gig but all my freelance and side projects work is in elm.
We use the react-select library a fair bit at work and I really wanted to use something like it in my elm projects but with better accessibility, and in pure Elm. I basically combined most of the feature set and styling of react-select with the combobox style accessibility which you can read more about here.
I hope it can provide some value for folks wanting a handsome looking single and multi select implemented in Elm.
Check out the package here
