Hello!

I have created a hook to implement some html

{
<div class="owl-item active"><div class="featuredItem col_lg_3 radiusCorners">
  <div class="imageArea col_6">
    <img src="https://images.you.gr/ecomfiles/410/410120_150.jpg" /></div>
  <div class="textArea col_6">
    <h3 class="title">Laptop HP 15.6'' (i5-8265U/4GB/1TB+128SSD/MX110 2GB/win10) 15-da1005nv</h3>
    <div class="price">
      <span class="final-price">499,00 €</span>
      <span class="old-price">698,99 €</span></div>
    <div class="productTags">
      <span class="specialTag bgOrange">-29%</span></div>
  </div>
  <a href="/ypologistes-perifereiaka/laptops/ola-ta-laptops/laptop-hp-15-6-(i5-8265u-4gb-1tb-128ssd-mx110-2gb">&nbsp;</a>
</div></div>
}

before the products on one of my category pages but no matter what hook location i choose it doesnt display anything...
I tried even simple html like h2 and it didnt show...

Ηοοk locations i tried after_header, before_content, before_footer...
