How to split region block render?

Question

Is it possible to split the rendering of the blocks in a region ? I have see this question Drupal 8 - How to split display the blocks separately in region.html.twig attempting to solve this by using {{ elements.search}} and I have tried it, but no success yet.

I also tried {{ elements.children[0] }} but this failed as well.

Is there a possible way of getting the array element out individually.

Many thanks

You can iterate through the blocks in this way:

{% for block_key, block in elements if block_key|first != '#' %}
  <b>{{ block_key }}: </b>
  {{ block }}
{% endfor %}

If you just need to know the blocks that are present in a given region, you could use this:

{{ dump(elements|keys) }}

Then you can print each block as:

{{ elements.key }}
