How to customize checkboxList in Yii2?

Question

Yii

Good afternoon.
There is a code:

foreach($types as $ck => $cv){
  $naa[$cv['id']] = $cv['name'];
}
echo $form->field($eventMain,'type',[
  'template' => "<label for=''>Выберите тип</label>                                             
  $chechBoxexForTypeFilter
  <div>{input}</div>",
  'options' => ['class' => 'class-radioCheckBox']
])->checkboxList(
  $naa,
  [
                 // 1
    'item' => function($index, $label, $name, $checked, $value) {
      $return = '<label>';
      $return .= '<input type="checkbox" name="' . $name . '"' . 'value="' . $value . '"' . ' >'."\n";
      $return .= '<i class="fa fa-square-o fa-2x"></i>' ."\n" .
      '<i class="fa fa-check-square-o fa-2x"></i>' ."\n";
      $return .= '<span>' . ucwords($label) . '</span>' ."\n";
      $return .= '</label>';

      return $return;
    },
    'id' => 'simpleFilterModal_radioCheckBox'
  ]
);

and the question is, how to forward the array to 'item', in order to put checkboxes on already marked elements by comparing with it?

Answer 1

function($index, $label, $name, $checked, $value)
checked isn't your responsibility for the parameter? check the default template.

Answer 2

In order for checked to be passed, $eventMain->type must have an array with checked values.

$eventMain->type = [1, 2, 5];
// а потом уже
...............
echo $form->field($eventMain,'type',[
  'template' => "<label for=''>Выберите тип</label>                                             
  $chechBoxexForTypeFilter
  <div>{input}</div>",
  'options' => ['class' => 'class-radioCheckBox']
])
