How to hide the lables of product sub-category?

hello i have a similar issue to some people below. The subheadings thing worked but it's still showing FREE. How do i remove this?

I have injected the following custom css code in form and that seems to solved your problem:

input[id*="1003"], input[id*="1066"]{

    display:none;

    pointer-events: none;

}

input[id*="1003"] + label > .form-product-details, input[id*="1066"] + label > .form-product-details{

display:none;

}

label[for*="1003"], label[for*="1066"]{

 font-weight: bold;

    text-decoration: underline;

    pointer-events: none;

}

span#input_23_1003_price {

    display: none;

}

span#input_23_1066_price {

    display: none;

}

Please check the screenshot below of your form:

Hope this helps.
