New Theme for site Select2 won't display

How Do I...
#1

Hi There,

I’ve used Select2 for years in our school’s Yii2 App. We are updating and changing our theme. Select2 won’t show in our new theme and I’ve been playing with it for days and can’t get it to show up.

Any ideas?

<?= $form->field($model, 'title_id')->widget(Select2::classname(), [
    'data' => ArrayHelper::map(\frontend\models\Titles::find()->where(['school_id'=>Yii::$app->user->identity->school_id])->all(), 'id', 'title'),
    'language' => 'en',
    'theme' => Select2::THEME_KRAJEE,
    'options' => ['placeholder' => 'Select a title ...'],
    'pluginOptions' => [
        'allowClear' => true
    ],
]); ?>
