Thanks for your answer, but you didn’t understand what I need.
I need to remove temporaly a custom option in the variable $product, because I use it to display some custom changes on the custom options ^^
By the way when I was looking to a way I found out how to remove for truth custom options…
This code will delete all custom options for a product (non obligatory option; an error occures for a required custom option but I don’t care to do this).
$options = $product->getOptions();
foreach ($options as $option)
All I need is to delete an option but only in my variable product, not in the whole product.
Maybe I can make a copy or something like this.
I hope you understand
