Building an accessible autocomplete control
Here’s a great in-depth post from Adam Silver about his journey to create an autocomplete field that’s as accessible as possible. There are so many edge cases to consider! There are old browsers and their peculiar quirks, there are accessibility best practices for screen readers, and not to mention dealing with the component design when there’s no JavaScript, etc.
Adam offers a warning before he begins:
[…] I’ve been looking at ways to let users enter a destination country. Unfortunately, native HTML form controls just aren’t good enough for this type of interaction. And so we need to build a custom autocomplete control from scratch. A word of warning though: this is one of the hardest UI components I’ve ever had to make—they’re just way harder than they look.
I also just bought Adam’s book, Form Design Patterns, and this post now makes me extra excited to read it.
