Wait for about 5 minutes and it will be installed. Then we can start using it as follows
//If your form is ActiveForm, please use

<code class="hljs xquery">use kartik\select2\Select2; 
//$data是键值对数组哦，key-value ,下面所声明的所有$data均为键值对数组，以该数组为例 
$data = [<span class="hljs-number">2 => <span class="hljs-string">'widget', <span class="hljs-number">3 => <span class="hljs-string">'dropDownList', <span class="hljs-number">4 => <span class="hljs-string">'yii2']; 
echo $form->field($model, <span class="hljs-string">'title')->widget(Select2::classname(), [  
    <span class="hljs-string">'data' => $data, 
    <span class="hljs-string">'options' => [<span class="hljs-string">'placeholder' => <span class="hljs-string">'请选择 ...'], 
]);
</span></span></span></span></span></span></span></span></span></span></span></code>

//If your form is non-ActiveForm, you can refer to the following

<code class="hljs php"><span class="hljs-keyword">use <span class="hljs-title">kartik\<span class="hljs-title">select2\<span class="hljs-title">Select2; 
<span class="hljs-keyword">echo Select2::widget([ <span class="hljs-string">'name' => <span class="hljs-string">'title', 
    <span class="hljs-string">'data' => $data, 
    <span class="hljs-string">'options' => [<span class="hljs-string">'placeholder' => <span class="hljs-string">'请选择...'] 
]);

</span></span></span></span></span></span></span></span></span></span></span></code>

When updating data that is not generated by ActiveFomr, it needs to be selected by default. It is easy to handle. Just add value

<code class="hljs php"><span class="hljs-keyword">use <span class="hljs-title">kartik\<span class="hljs-title">select2\<span class="hljs-title">Select2; 
<span class="hljs-keyword">echo Select2::widget([ 
    <span class="hljs-string">'name' => <span class="hljs-string">'title', 
    <span class="hljs-string">'value' => <span class="hljs-number">2, 
    <span class="hljs-string">'data' => $data, 
    <span class="hljs-string">'options' => [<span class="hljs-string">'placeholder' => <span class="hljs-string">'请选择...'] 
]);
<span class="hljs-comment">#但是如果你的表单是ActiveForm生成的，但是往往字段不是表字段怎么办呢？更好办啦，以上面的为例，你只需要指定$model->title = ['title1', 'title2'];即可

</span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>
