$ composer require openforce/select2-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...

Step 4: Add select2 to your template

//Add your template file
<script src="//code.jquery.com/jquery-1.9.0rc1.js"></script>
<link href="//cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css" rel="stylesheet" />

How to use

The main options are:

• class Required. Your target entity.
• search_field Required. Entity field name you want to use for your search.
• choice_label Optional. Entity field name you want to display on the label. default value is __toString.
• max_results Optional. Number to display on page.
• filter Optional. It is callback function. If you use this, you don't need to define search_field.
• related_fields Optional. This option allows you to use the values you enter in other fields with the filter option.

// your Controller file
    public function index(){

        $formBuildr = $this->createFormBuilder();
        $formBuilder->add('price', InputType::class);
        $formBuilder->add("product", Select2Type::class,[
            'class' => Product::class, 
            'search_field' => 'name', 
            'choice_label' => 'name',
            'max_results' => 50, 
            'related_fields' => ['price'],
            'filter' => function(EntityRepository $er, $value, $relatedFields){
                return $er->createQueryBuilder("p")
                    ->where("p.description like :word and p.price < :price")
                    ->setParameter("word", "%".$value."%")
                    ->setParameter('price', $relatedFields['price'])
                    ->orderBy("p.productId")
