Thank you for your kind words :)

Please inject the following CSS to style the product category:

input[id*="input_26_1010"] {

  display: none;

}

input[id*="input_26_1010"] + label > .form-product-details {

  display: none;

}

label[for*="input_26_1010"] {

  font-weight: bold;

  text-decoration: underline;

}
