I want to use dynamic form widget (wbraganca). I tried it using the tutorial by 'doingItEasy' channel & also by github. And wrote following code :
controller code -
public function actionCreate()
{
$model = new Vendors();
$modelsSubCat = [new BusinessSubCategories];
if ($model->load(Yii::$app->request->post()) && $model->save()) {
$modelsSubCat = Model::createMultiple(BusinessSubCategories::classname());
Model::loadMultiple($modelsSubCat, Yii::$app->request->post());
// validate all models
$valid = $model->validate();
$valid = Model::validateMultiple($modelsSubCat) && $valid;
$modelsSubCat = Model::createMultiple(BusinessSubCategories::classname());
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
foreach ($modelsSubCat as $modelSubCat) {
$model->ven_sub_category_id = $modelSubCat->bsc_id;
if (! ($flag = $modelSubCat->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $model->ven_id]);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
} else {
return $this->render('create', [
'model' => $model,
'modelsSubCat' => (empty($modelsSubCat)) ? [new BusinessSubCategories] : $modelsSubCat
]);
}
}
'_form.php' code -
<?php

'create.php' code -
<?php
use yii\helpers\Html;
/* @var $this yii\web\View */
/* @var $model backend\models\Vendors */
$this->title = Yii::t('app', 'Create Vendors');
$this->params['breadcrumbs'][] = ['label' => Yii::t('app', 'Vendors'), 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="vendors-create">
<h1><?= Html::encode($this->title) ?></h1>
<?= $this->render('_form', [
'model' => $model,
'modelsSubCat' => $modelsSubCat
]) ?>
</div>
But What happens is that the add/remove button is not working. I'm showing it's screenshot - Screenshot with Add/remove buttons
