I solved by myself 😀

Edit themes/default-bootstrap/js/modules/blocktopmenu/js/blocktopmenu.js 
and add line below in function

function mobileInit()
{

    categoryMenu.superfish('destroy');
    $('.sf-menu').removeAttr('style');

// ADD THIS LINE
    $(".sf-contener .cat-title").toggleClass('active').parent().find('ul.menu-content').stop().slideToggle('medium');
