Brands in order of quantity of products they contain

[Marcso]

Good morning,
I hope you can help me.
I would like to insert a code that would allow me to show the logos of the brands in order of quantity of products that these brands contain. Currently the list of brands is shown in alphabetical order. I would like to insert this code inside a widget that I would put inside the main menu.
I am attaching the code I have at the moment. This code adjusts the display of the widget. Thank you very much.

Marco

    {if isset($widget_heading)&&!empty($widget_heading)}

        {$widget_heading}
