With a model ¶

<?php

?>

<?= Chosen::widget([
    'model' => $model,
    'attribute' => 'selectable_attr',
    'items' => [1 => 'First item', 2 => 'Second item', 3 => 'Third item'],
    'multiple' => true,
]);?>

<?= $form->field($model, 'selectable_attr')->widget(
    Chosen::className(), [
        'items' => [1 => 'First item', 2 => 'Second item', 3 => 'Third item'],
        'disableSearch' => 5, // Search input will be disabled while there are fewer than 5 items
        'clientOptions' => [
            'search_contains' => true,
            'single_backstroke_delete' => false,
        ]
]);?>

Without a model ¶

    'items' => [1 => 'First item', 2 => 'Second item', 3 => 'Third item'],

    ]
]);?>
