Why doesn't DateRangePicker (kartik-v) YII2 work?

Question

Yii

I installed the extension via composer. I display the widget in view:

<?php
echo '<label class="control-label">Date Range</label>';
echo '<div class="drp-container">';
echo DateRangePicker::widget([
    'name'=>'date_range_2',
    'presetDropdown'=>true,
    'hideInput'=>true
]);
echo '</div>';
?>

The widget is displayed, but when you click on it, nothing happens. The console does not give any errors.
What could be the problem? As I understand it, neither
CSS nor JS files were loaded ... how to fix it? When using the usual render, everything worked.

"As I understand it, neither CSS nor JS files were loaded..." how did you understand this? I look at the "Network" tab in the browser console, and there is a javaScript filter. and if something is not loaded, you can see it there.
Most likely you just have two identical $model->date_range_2 fields on the page, one is in the search form in: <?php echo $this->render('_search', ['model' => $searchModel]); ?> and the other one you specified.
And the calendar is hung on the first.
