Unable to use multi select box

[OpenCart City 0]

Hello,

We are trying to set multiple select option in select box but getting the issue. So below is the code we are trying to use:

array(
  'type' => 'select',
  'multiple' => true,
  'label' => $this->l('Test'),
  'name' => 'TEST',
  'options' => array(
    'query' => array(
        array('id' => 'demo', 'name' => 'demo'),
        array('id' => 'dummy', 'name' => 'dummy'),
    ),
    'id' => 'id',
    'name' => 'name',
  )
),

We are getting the undefined index issue. So please can some one correct this code.

Thanks!
