I want to have a form textfield automatically uppercase the text entered as it is typed in. I was hoping that there was as set-able property that would allow for this but I’m unable to find one.
$form['elementName'] = array( '#type' => 'textfield', '#title' => $this->t('Address'),... )
The searches I have done so far point to the use of ‘Plugins.’ However if there is a simple(er) solution I prefer that. Any ideas appreciated;
