autocomplete Attribute
The autocomplete attribute specifies that the form or input field should have an autocomplete function.Note: The autocomplete attribute works with <form>, and the following <input> types: text, search, url, telephone, email, password, datepickers, range, and color.
When the user starts to type in an autocomplete field, the browser should display options to fill in the field:
Example
<form action="demo_form.asp" method="get" autocomplete="on">
First name: <input type="text" name="fname" /><br />
Last name: <input type="text" name="lname" /><br />
E-mail: <input type="email" name="email" autocomplete="off" /><br />
<input type="submit" />
</form>
First name: <input type="text" name="fname" /><br />
Last name: <input type="text" name="lname" /><br />
E-mail: <input type="email" name="email" autocomplete="off" /><br />
<input type="submit" />
</form>
Note: In some browsers you may need to activate the
autocomplete function for this to work.
Note: The autofocus attribute works with all <input> types.
autofocus Attribute

<input type="submit" />
</form>
Last name: <input type="text" name="lname" form="user_form" />
First name:<input type="text" name="fname" />
