I am adding a plugin to Magento 1 that requires a Custom Option on each simple product to add a further charge to the product should this particular service be requested by a customer.
However, if the service is not being requested, I would prefer the drop down menu of the Custom Option not to appear - in fact it does not need to be shown to the customer at all.
Has anyone any idea how, if at all this can be achieved?
I did try the 'Hidden' option in the Magento backend, which did hide the drop down menu, but also removed the functionality of it too.
Thanks for any help on this.
Not a clever solution, but could you hide with CSS instead?
