如何使用表单助手禁用cakephp中的select的单个选项？

Question

I need to disable a single particular option of a selectbox with form helper in cakephp. I am creating selectbox with below way :

<?php 
    $options = array(1=>'Option 1',2=>'Option 2',3=>'Option 3')
    echo $this->Form->input('Model.field', array('options' => $options, 'empty' => '--select--')); 
?>

So now i need to disable Option 2 in selectbox like :

<select id="dropdown" name="dropdown">
    <option value="1">Option1</option>
    <option value="2" disabled="disabled">Option2</option>
    <option value="3">Option3</option>
</select>

So is there any disable property available in options array to disable single options?

Thanks in adavance.

As per the reference of CakePHP .

Your can add disabled attribute like the below:

    $options = array(1=>'Option 1',2=>'Option 2',3=>'Option 3')
    echo $this->Form->input('Model.field', array('options' => $options, 'disabled' => array(2), 'empty' => '--select--'));
