This is a terrific demonstration of how far the platform has come: a richly styled select that leans on native semantics, native accessibility, and progressive enhancement instead of fighting the browser.

What I especially appreciate here is the restraint. Yes, there’s some clever CSS and a little JavaScript to help with positioning, but the whole thing is built on top of the platform, not in spite of it. That’s the interesting takeaway for me: we can build interfaces that feel bespoke without throwing away the reliability and accessibility native controls already give us.
