I'm making custom admin extension, where I have the grid, where one column is checkbox column.
$this->addColumn('is_holiday', array( 'header' => Mage::helper('plan')->__('Holiday'), 'align' =>'center', 'width' => '120px', 'index' => 'is_holiday', 'type' => 'checkbox', 'values' => array(1), 'disabled' => true, 'readonly' => true, ));
It is rendered ok, but it is editable - user can change the value. I'd like to disable this functionality.
How can I do that?
Have you seen any checkbox in the admin panel with a un-editable checkbox?
That will be the first point as reference.
