Can you tell me how to make it possible to insert a block through every 3rd element. The picture shows where it should be. How can I do it? Thanks in advance.

Answer 1

<?= ListView::widget([
        'dataProvider' => $dataProvider,
        'itemOptions' => ['tag' => false],
     //'itemView' => '_teaser',
        'itemView' => function ($model, $key, $index, $widget) {
            return $this->render('_teaser', [
                'model' => $model,
                'key' => $key,
                'index' => $index,
                'widget' => $widget,
            ]);
        }
    ]) ?>

in '_teaser.php' $index can be processed

<div class="item" data-key="<?=$model->id?>">
...
</div>

<?php if (($index+1) % 3 == 0) : ?>
я после третьего?
<?php endif; ?>
