        $this->getMassactionBlock()->addItem('assign_group', array(
             'label'        => Mage::helper('customer')->__('Assign a Customer Group'),
             'url'          => $this->getUrl('*/*/massAssignGroup'),
             'additional'   => array(
                'visibility'    => array(
                     'name'     => 'group',
                     'type'     => 'select',

  • could you show us your complete code as this snippet is probably not enough to get a good answer from. May 18 '15 at 16:18
  • this method i used in observer to add action in order gird but after ajax call sub option are not working. May 18 '15 at 16:22
  • update my question check it May 18 '15 at 17:24
  • What do you mean after the ajax call? May 20 '15 at 4:38
  • grid ajax call. when grid content update with ajax May 20 '15 at 4:39

After carefully examine your code so i found where is your problem. it is prototype handler problem. can not create the handler for this action. if i edit the core file it is working other after ajax reload grid it is not working. So i create the simple solution add my javascript function on ajax call and it is working.

so finally you add this function in your code and your problem will be resolved:

<script type="text/javascript">
    $("sales_order_grid_massaction-select").observe("change", function(event) {
  • thanks for your attempt it is not magento way of doing but at least solve the problem.. May 21 '15 at 6:46
