i have modified slae.order report to display the sales order line when the quantity is not zero using the code below
<tr t-att-class="'bg-200 font-weight-bold o_line_section' if line.display_type == 'line_section' else 'font-italic o_line_note' if line.display_type == 'line_note' else ''">
<t t-if="line.product_uom_qty != 0">
this is working well while i am printing the quotation but the line still displaying in the customer preview .
how can i hide the sales order lines when quantity is zero in the customer preview?
