Hi there!
I was able to make Nemo1's tutorial work with Prestashop 1.6
There's just one additional step compared to version 1.5. You need to override form.tpl (controllers/admin/templates/products/helpers/form) and there, comment out line 116. Basically, this is the original code:
else if (product_type == product_type_virtual)
{
$('a[id*="Pack"]').hide();
$('a[id*="Shipping"]').hide();
$('a[id*="Combinations"]').hide();
}[
and this should be the final one:
else if (product_type == product_type_virtual)
{
$('a[id*="Pack"]').hide();
$('a[id*="Shipping"]').hide();
//$('a[id*="Combinations"]').hide();
}
Hope this helps
