Using JavaScript / HTML, I want the users of my site to only be allowed to choose Year-Month-Date-Hour and not minutes. The html element allows to also pick minutes. Maybe the right way to solve this is simply not using the datetime-local type of input, in that case please guide me to the correct tool. Otherwise, I'd appreciate to learn how to remove minutes from this element so users can't choose the minutes of the selected datetime. Also, I tried the step attribute but it doesn't seem to do the trick. Any help is appreciated.
