Form Design Patterns Book by Adam Silver
Oh, this will be good! Adam has been working on, thinking and writing about forms for quite a while and he has distilled that down into ten patterns. You just know that progressive enhancement will be at the heart of this book.
By the end of the book, you’ll have a close-to exhaustive list of ready-to-go components, delivered as a design system that you can fork, contribute to and use immediately on your projects. But more than that, you’ll have the mindset and rationale behind when or when not to use each solution, which is just as important as the solution itself.
