I was wondering how you would handle the occasion where the dropdown overflows off the page?

Always look forward to the revival of this site every December!

Agreed, accessible custom selects are necessary and we should not always push the native if use cases are not solved by it. I would also like to share my learnings when diving into this problem: https://www.technica11y.org/making-custom-selects-accessible

Custom Selects are not going away, so I think it’s important that we explore ways to make this usable for everyone.

I’m familiar with the aria concepts, but find them hard to put together for anything non-trivial. Thanks for running through a complete example. It’s especially useful to see the part about the hidden “count” while typing, since that’s not an obvious thing (as a sighted user).
