I have a common list of items in a quote for customer layout (attached).
Sometimes user need to have a subtotal of some of these items (usually not all, just any of them).
I can use a check box for each item to determinate which one will go to do a subtotal, but how can I do this ?
Do I need to re-open a different layout with a resume based upon checked items ?
And what about other items, items that don't need a subtotal ?
