- Add
autocomplete="off"
onto<form>
element; - Add hidden
<input>
withautocomplete="false"
as a first children element of the form.
<form autocomplete="off" method="post" action="">
<input autocomplete="false" name="hidden" type="text" style="display:none;">
...
This formation is going to prevent Chrome and Firefox to offer autofill and autocomplete for all input fields inside the form.
This works for me on fresh Chrome v. 122.0 (more info here)
(I test it in my angular dropdown component - works also without
<form>
wrapper)
