Inheritance	yii\grid\CheckboxColumn » yii\grid\Column » yii\base\BaseObject
Implements	yii\base\Configurable
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/grid/CheckboxColumn.php

CheckboxColumn displays a column of checkboxes in a grid view.

To add a CheckboxColumn to the yii\grid\GridView, add it to the columns configuration as follows:

'columns' => [
    // ...
    [
        'class' => 'yii\grid\CheckboxColumn',
        // you may configure additional properties here
    ],
]

Users may click on the checkboxes to select rows of the grid. The selected rows may be obtained by calling the following JavaScript code:

var keys = $('#grid').yiiGridView('getSelectedRows');
// keys is an array consisting of the keys associated with the selected rows

For more details and usage information on CheckboxColumn, see the guide article on data widgets.

Property Details

$checkboxOptions public property

The HTML attributes for checkboxes. This can either be an array of attributes or an anonymous function (Closure) that returns such an array. The signature of the function should be the following: function ($model, $key, $index, $column). Where $model, $key, and $index refer to the model, key and index of the row currently being rendered and $column is a reference to the yii\grid\CheckboxColumn object. A function may be used to assign different attributes to different rows based on the data in that row. Specifically if you want to set a different value for the checkbox you can use this option in the following way (in this example using the name attribute of the model):

'checkboxOptions' => function ($model, $key, $index, $column) {
    return ['value' => $model->name];
}

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.
