            {% if attribute(structure, 'breadcrumb') is defined %}
                {% for item in structure.breadcrumb(pageInStructure.uid) %}
                    <li class="breadcrumb-item">
                        {%  if attribute(paths, [pageInStructure.sid, item.id]|join(':'))|default(false) %}
                            <a href="{{ path('match_all', {path: attribute(paths, [pageInStructure.sid, item.id]|join(':')) }) }}">
