Here is the code for grouping...

<t t-set="product_category" t-value="[]"/>
<t t-foreach="o.order_line" t-as="l">
    <t t-set="product_category" t-value="product_category+[l.product_id.categ_id]"/>
</t>
<t t-foreach="set(product_category)" t-as="category">
    <div><strong t-esc="category.name"/></div>
    <t t-foreach="o.order_line" t-as="l">
        <t t-if="category.id==l.product_id.categ_id.id">
            <div><span t-field="l.product_id"/></div>
        </t>
    </t>
</t>

Hello,
what have I to do group on main product that has several optional products connected ?
Now I got something like this in Order and Invoice.
Main product x ------ 0
Opt prod 1 --- 10€
Opt prod 3 --- 22€
.... so on

I would like to have a grouping on main product like this 

Main product x ------ 32€
Main product y ------ 56€
Main product z ------ 34€
Totale ----------------122€

Thanks
