How to hide html block in MODX if there are no neighbors of the same parent?

Question

MODX

There is a block

<section class="products">
          <div class="cont">
            <div class="data">
              <div class="block_head">
                <div class="title">Другие серии</div>
                <a href="/" class="all_link link transition">
                  Смотреть все
                  <div class="hover"></div>
                </a>
              </div>
              <div class="flex">
                
              </div>
            </div>
          </div>
        </section>

pdoResources displays neighboring resources, but how to make sure that if there are no neighboring resources, then the block is completely hidden?
