Hi,
Flexv2.php is not the correct file to make this modification.
Because Custom Fields (inside the "Specification" TAB) are listed in the product details layout by the PHP line of
echo $this->loadTemplate('customfields');
Which triggers this PHP file:
/component/com_virtuemart/views/productdetails/tmpl/default_customfields.php
But i won't suggest you to touch any PHP file in that directory, since those are core files.
Try to achieve what you are looking for with CSS.
That field is the "Descrption" field, and its DIV.class is "product-field-desc"
Using this CSS rule below should do the trick to hide the "description" text:
.product-fields .product-field-desc {
display:none;
}
If this CSS rule doesn't work for you, then try to come up with a different CSS solution,
but since what you are asking is a custom modification; providing you support about this issue is beyond our free support.
Regards.
