display index using bootstrap collapse widget

Yii 2.0 Extensions
1

I’ve tried displaying my Faq entries using kartik’s gridview and expand column but I couldn’t get the expanded row’s data to wrap so I’m trying to use the collapse widget to display faq answers to the questions when clicked on. What am I doing wrong here?

I get error:

exception ‘yii\base\InvalidConfigException’ with message ‘The ‘label’ option is required.’ in /home/drcarr/public_html/vendor/yiisoft/yii2-bootstrap/Collapse.php:107

index.php




$faqs = [];


foreach ($dataProvider as $faq => $faqs[]) {

    $faqs[] = [

        'label' => $model->faq_question,

        'content' => $model->faq_answer,

    ];

}

?>


<div class="site-about">

    <h1><?= Html::encode($this->title) ?></h1>

    

   <?= Collapse::widget(['items'=> $faqs]);

    ?>


</div>

controller:




public function actionIndex()

    {

        $searchModel = new FaqSearch();

        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        

        return $this->render('index', [

            'searchModel' => $searchModel,

            'dataProvider' => $dataProvider,

        ]);

    }

I also tried adding an array to the model, but am not really sure if/how to use it in this instance:




public function getFaqs()

    {

        return ArrayHelper::map(Faq::find->all(),'id','faq_question','faq_answer');

    }
