alt Hacker NewsI didn't know about <datalist>, but how are you supposed to use it with a non-trivial amount of items in the list? I don't see how this can be a replacement for javascript/XHR based autocomplete.

It can't do complex autocomplete. It's ok for simple cases only. I use it with a 25k long list to ease the input. Works well enough for this.

You can't. It's only supposed to be used for a limited list.
And even if you allow XHR and add options to a <datalist>, it still has terrible UX.
Don't use it, it totally blows. For another oddity to not use, check out the multiple select: https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/...
Expecting users to press modifiers when clicking on these is so funny.
