Existe la posibilidad de hacer un combobox dependiente solo con HTML5?

Question

combobox dependiente de tres niveles

Answer 1

I don't believe HTML does that by itself, but combined with JavaScript, yes. Also, it'll depend where you want to pull the info from, so you could even use PHP (or similar) with it to populate it from a database so it's dynamic. Even jQuery could be useful with that and you could use AJAX to send your requests to a PHP file to handle.
