'm trying to display a list of products group by category on a Qweb Report in Odoo17. I created my list in a python class. After the process, this python list looks like this :

{
    'Office Furniture': 
    [
        {'name': 'Chair floor protection\nOffice chairs can harm your floor: protect it.', 'cat': 'Office Furniture'}, 
        {'name': 'Chair floor protection\nOffice chairs can harm your floor: protect it.', 'cat': 'Office Furniture'}
    ], 
    'Services': 
    [
        {'name': 'Deposit', 'cat': 'Services'}
    ]
}

On the Qweb side I loop through this list to display the name of products after the category. I return the category but can't figure out how display the products related to each category :

Could you please help ?

Thanks a lot
