Hi Ivan,

something like (after your layers have been loaded in the map panel):

        map_panello.layers.each(function(record) {
                if (record.get('layer').isBaseLayer == true) {
                     record.set("hideInLegend", true);
                }
            });

Best regards,
Bart
