  <?php 
    $data = array('101' => 'Faraz Khan', '102' => 'Depesh Saini', '103' => 'Nalin Gehlot', '104' => 'Hari Maliya');
    $selected   = array(
      '102' => array('selected' => 'selected'),
      '103' => array('selected' => 'selected'),
    );
    $htmlOptions = array('size' => '5', 'prompt'=>'Use CTRL to Select Multiple Staff', 'multiple' => 'true', 'options' => $selected);
    echo $form->listBox($model,'staff_id', $data, $htmlOptions);
  ?>
  <?php echo $form->error($model,'staff_id'); ?>
 </div>

Problem

I have a `multiple select-list-box` for `Staff` in `Create-Service-Form`, used to select multiple staff when creating a new service. for this i can assign multiple staff on a single service. I saved `staff_id` field as: `$model->staff_id = serialize($model->staff_id);` Here the update-view code for multiple-select-list-box: ``` <div class="row"> <?php echo $form->labelEx($model,'staff_id'); ?> <?php $data = array('1' => 'Sam', '2' => 'john', '3' => 'addy'); $htmlOptions = array('size' => '5', 'prompt'=>'Use CTRL to Select Multiple Staff', 'multiple' => 'multiple'); echo $form->ListBox($model,'staff_id', $data, $htmlOptions); ?> <?php echo $form->error($model,'staff_id'); ?> </div> ``` Problem is, when i load form for updating a service. how do i select those staff, which are previously saved in database? I tried this dropDownList-attributes, but it not working. $select | string | the selected value if someone has solution, then suggest me. Thanks All Mates...
