Product Characteristics all are in Cart by default

-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.3

Hi,
I have product characteristic and varient with my products. When some one add to cart a product all characteristic goes to shoping cart when none of them were selected. Please check my website(its under development) and add to cart a product without selecting any characteristics. You will see in shopin cart module all characteristic are there.
Is there any way to get rid from that. I want the characteristic to show in cart when it was selected.

Thank you.

Hi,
I have selected Yes to "Group options with product". But still those are there with slight changes than previous. Any suggestion please ?

Hello Jerome,
Yes, those articles helped me to solve the issue.
I had to add this line $this->values[] = JHTML::_('select.option', 0,JText::_('HIKASHOP_NO')); and
if($default){
// $value = $variant->product_id;
$value=0;
}
And finally select "No" to Group Options with Product to get individual price for each item in cart.
You can close this issue as sloved

Best Regards.
