title: How can I reuse a block multiple times?
body: <p>How can I render a block multiple times within a view in a twig template? Currently I do have a block, let's call it <code>something</code> defined in an included (via <code>render</code>) twig file. I then include it at the layout-twig file using the following:</p>
  
  <pre><code>{% block something %}{% endblock %}
  </code></pre>
  
  <p>Everything is fine, however as soon as I call this tag a second time, I get the following error message:</p>
  
  <pre><code>The block 'something ' has already been defined in "::layout.html.twig" 
  </code></pre>
  
  <p>Therefore: How can I render a block multiple times?</p>
