    <li data-filename="file 2">file 2</li>
    <li data-filename="file 3">file 3</li>
</ul>

####2. Call widget

<?= \x1\dragula\Dragula::widget([
    'containers' => ['#files'],
    'options'    => [
        'revertOnSpill' => true,
    ],
    'drop' => new \yii\web\JsExpression('my.dropped'),
]); ?>

####3. Javascript for handling drop event

<script>
    var my = {};

    my.dropped = function(el, container) {
        var c      = $(container);
        var items  = c.find('li[data-filename]');
        var result = [];
        $.each(c.find('li[data-filename]'), function(key, item) {
            result.push($(item).data('filename'));
        });

        console.log('result', result);
        // your logic here, e.g. ajax post
    }
</script>

Note that i used jquery in my example code, which is optional and not referenced by this project.

Also, you have to take care of script loading order yourself!
