I need to customize the sale_view, inserting 20 horizontal column quantity in the order. I tried to use the group tag. A group is a grid with two columns. A field and its label take two columns, so adding fields inside a group will have them stacked vertically. If we nest two group elements inside a top group, we will be able to get two columns of fields with labels, side by side. But i need 20 column, How can manage it?

Thanks
