+AjaxSubmitButton for Yii 2
+=====================================
+
+This is the AjaxSubmitButton widget that renders an ajax button which is very similar to ajaxSubmitButton from Yii1 for Yii 2. 
+
+Example of usage of the widget with form and other custom widget (in this case Select2).
+
+The view:
+```php
+use demogorgorn\ajax\AjaxSubmitButton;
+
+<?php echo Html::beginForm('', 'post', ['class'=>'uk-width-medium-1-1 uk-form uk-form-horizontal']); ?>
+      
+<?= Select2::widget([
+    'name' => 'country_code',
+    'data' => Country::getAllCountries(),
+    'options' => [
+        'id' => 'country_select',
+        'multiple' => false, 
+        'placeholder' => 'Choose...',
+        'class' => 'uk-width-medium-7-10']
+     ]);
+?>
+       
+<?php AjaxSubmitButton::begin([
+    'label' => 'Check',
+    'ajaxOptions' => [
+        'type'=>'POST',
+        'url'=>'country/getinfo',
+        /*'cache' => false,*/
+        'success' => new \yii\web\JsExpression('function(html){
+            $("#output").html(html);
+            }'),
+    ],
+    'options' => ['class' => 'customclass', 'type' => 'submit'],
+    ]);
+    AjaxSubmitButton::end();
+?>
+            
+<?php echo Html::endForm(); ?>
+
+<div id="output"></div>
+```
+
+Please note: that #output is a div element which will be updated.
+
+In controller:
+```php
+public function actionGetinfo()
+{
+    if(!isset($_POST['country_code']) || empty($_POST['country_code']))
+        return;
+
+    $code = $_POST['country_code'];
+
+    return $this->renderAjax('resultwidget', ['code' => $code]);
+}
+```
+
