Preset values keeping values after a page is reloaded

[itepifanio]

Describe the bug When it's used the items parameter the values are kept after the user reload the page.

To Reproduce Steps to reproduce the behavior:

1. Go to the demo page.
2. Check the "Preset values passed through options" and reload the page. The values are been kept on firefox.

Expected behavior I think the choices input should have autocomplete="off" as default. This fixes the problem.
