That works great!
Is there a way that we can have those columns only show if there is an item added to the cart from that column? Right now if we add each "checkbox" item to the column list, we have a very wide cart display page. As an example, we add "Smoked Turkey" to the column (since that is one of the sandwich choices) along with 7 others. If someone selects only 4 sandwiches, we have the other 4 items showing (as column headers) in the cart display, but they are empty. Any way to avoid such a wide cart display???
