It just does not work, the up button appears but none of the type buttons work. I have already tried using materialize via CDN and local but there was no change. I believe that there is no error in the code because after much trying and not working I took the example of the site itself and even then nothing ... code follows:
<!DOCTYPE html>

<meta charset="utf-8">
