    'style' => FileInput::STYLE_IMAGE
]);?>

Example 2: `php <?= FileInput::widget([ 'name' => 'Image[name][]', 'style' => FileInput::STYLE_INPUT, //'style' => FileInput::STYLE_CUSTOM, //'customView' => __DIR__ . '/widgets/file_input.php', 'addMoreButton' => true, 'buttonCaption' => 'Дбавить еще', ])?> `

      if ($(this)[0].files) {
        $.each($(this)[0].files, function (i, file) {
          if(file.size) {
            form.append(field_name, file);
          }
