CakePHP disable some radio buttons?

Question

I have a simple form with some radio buttons. I want to disable some of the radio buttons, is this possible?

$sixMonths = true;
$twelveMonths = true;
$twentyfourMonths = false;

echo $this->McForm->create('Wizard',  array ('url'=>'/wizard/create'));

$options = array('24' => '24 months','12' => '12 months', '6' => '6 months');
$attributes = array('legend' =>false, 'default' => '6');
echo $this->McForm->radio('period', $options, $attributes);

echo $this->McForm->submit('Save');
echo $this->McForm->end();

So in this case I'd like to disable the first radio button and enable the other two.

I know I could probably do it with jQuery, but I'd prefer to do it without using it, is it possible? Any ideas?

Thanks!

You can add a disabled array in $attributes that contains the values ​​of the radios:

$attributes = [
    'legend' => false, 
    'default' => '6', 
    'disabled' => ['6', '24']
];
