Browser - Prevent autocompletion box from showing?

Question

Is it possible to prevent the autocompletion box from showing?

As you can see I am showing a datetime picker, but there is a autocompletion box in the way. Can I prevent it from showing?

Answer 1

have you tried autocomplete="off"

Answer 2

You probably have the autocomplete attribute on your calendar input which may appear something like this:

<input autocomplete="username">

Try switch to false?

<input autocomplete="false">
