Resolved:

<ul class="js-selected-category c-content-categories__selected-list" id="breadcrumbs">

@while ($category->parent != null)
    <?php $lists[] = $category->parent; ?>
    <?php $category = $category->parent; ?>
@endwhile

<?php $lists = array_reverse($lists,true); ?>

@foreach ($lists as $cate)
    <li class="c-content-categories__selected-category">
        {{ $cate->name }}
    </li>
@endforeach

</ul>
