Collapsible row problem metafield

Hello! I would like to add a collapsible row; in this case only to the sunglasses pages of my shop. not anywhere else. How can I do this? Here’s my website.

https://www.xmine23.com/collections/occhiali-da-sole-1/products/sbm782-black-copia

I’ve tried with metafields, but i’cant figure out how to use it.

Thanks in advance.

@vivvy1522 Where are the collapses?

sorry, I forgot to save hehe. if you refresh the page you can see where the collapsible row should be. thanks

possible with metafield.
other shortcut method is:
paste in theme.liquid at the end

{% if product.handle == 'products/sbm782-black-copia' %}

  .product-text>.toggle {
    display: block;
}
  {% else %}
    .product-text>.toggle {
    display: none;
}

  {% endif %}
    

Thanks for your answer, but it not work.

@vivvy1522 ohh sorry little mistake

{% if product.handle == 'sbm782-black-copia' %}

  .product-text>.toggle {
    display: block;
}
  {% else %}
    .product-text>.toggle {
    display: none;
}

  {% endif %}
