Block Content Selected

With Block Content Selected you can easily select the nodes to be displayed in current block with autocomplete and also the choice of view mode.

If you want to customize the display of the content of block, just overload the block with the use of variable content['#bcs_items'] in the file of the current block template.

example in block--idBlock.html.twig :

{% block content %}
  {% set items = content['#bcs_items']  %}
  {% for item in items %}
    {{ item.title.value }}
  {% endfor %}
{% endblock %}
