Hi,
It seems like the <optgroup> tag only accepts 2 attributes:
Zend\Form\View\Helper\FormSelect.php [Line:61]
protected $validOptgroupAttributes = array(
'disabled' => true,
'label' => true,
);
Is there a way to add a valid HTML5 global parameter to it?
for example:
..array(
'label' => 'Optgroup Label',
'options' => array(...options...),
'attributes' => array(
*'class' => 'optgroup-class'*,
),
),
As per the following doc:
http://www.w3.org/TR/html-markup/optgroup.html
Permitted attributes: * global attributes
<http://www.w3.org/TR/html-markup/global-attributes.html> * & label &
disabled
Thanks!
Roman.
