    $('a.mobile-drop-button.sub img').on("click", function(e){
    alert('3rd level');
        $(this).addClass('activeSubNav')

        $(".dropdown-menu-sub").show();
        e.preventDefault();
    })

    /*****
        SUB NAVIGATION ENDS
    ******************/

Appreciate your help!

Thanks!!

I have fixed the Issue by using jQuery "slideToggle & sibblings()", as this HTML was so complicated that i dint find correct DOM Flow.

Finally Fixed :-) JS :

$('#navigation .mobile-drop-button-sub').on('click', function(){
        var abc = $(this).closest('.menu-option-sub').find('.dropdown-menu-sub').css({'height':'auto'}).height();
        //$(this).closest('.menu-option-sub').find('.dropdown-menu-sub').closest('ul.dropdown-menu').css({'height': height + abc})
        $(this).closest('.menu-option-sub').find('.dropdown-menu-sub').closest('ul.dropdown-menu').css({'height': height + abc})
        $(this).closest('.menu-option-sub').find('ul.dropdown-menu-sub').slideToggle('fast', function(){
            $(this).css('height', abc);
            $(this).closest('.menu-option-sub').siblings().find('ul.dropdown-menu-sub').css('display','none');
                /* $(this).closest('.menu-option-sub').parent('ul.dropdown-menu').css({
                    'height':'auto'
                }); */

                $(this).closest('.menu-option-sub').parent('ul.dropdown-menu').css({
                    'height':'auto'
                });

        });
    })
