Hi, i want to adress a textfield in a html page, but its not part of any form

Seeing how WWW::Mechanize uses HTML::Form which only deals with stuff in forms, you cannot adress any such textfield, it doesn't exist in the HTML::Form object

The good news is you don't need to submit any form object to make get/post requests, just use the get/post method as documented

 $ua->get( $url , $field_name => $value, ... )
