Hey Medu….you’re sort of correct….it is possible to delete an item in the checkout form…..its not advisable.
However let me suggest a better way to this. In the settings area within the plugin…click on the tab for Checkout….at the very top of the first line of the checkout “defalut” form you’ll see a drop down arrow…to the right of that you’ll see the word Filter and then to the right of that you will see +Add New Form Set.
Create your own form set and then once you’ve completed doing that make sure you click save changes…and then..select it from the drop down and make sure you scroll back down to the bottom and click “Save Changes” again….now that checkout form will be active and the default checkout form will be inactive.
That should help you. Thanks again,
RC
