alt Hacker NewsJust a heads up but datalist is not really a great solution if you need a strong contract. The user can still type whatever they want into the field and there is no fuzzy filtering or typo mitigation. Once you add those requirements, a library that gives you a more fully featured combobox is likely going to make a lot of sense in your project.

There’s still browser/OS typo mitigation.
Wow, yeah - years later and I still get nothing in Firefox, and support is quite spotty in general (and clearly still buggy): https://caniuse.com/?search=datalist
Hard pass, that's essentially unusable.
That's the whole sanitize vs. validate argument debate that keeps coming up.
How you handle it is project-dependent. But if you're doing a real web site, not an SPA, you can show an error/help page, or re-load the current page with the error/help message.
Very true, and ran into this one specifically myself when going down the "HTML can do this!" road. HTML can NOT, in fact, replace a good combobox with search input. Datalist has significant shortcomings. I wound up using a React island for this single input inside otherwise normal HTML, despite my own objections, because it really it just that much better than the native options.
