/* Anything that gets to the document
   will hide the dropdown */
$(document).click(function(){
  $(".Navigation-listItem.is-dropdown").addClass('is-hidden');

/* Clicks within the dropdown won't make
   it past the dropdown itself */
$(".Navigation-listItem.is-dropdown").click(function(e){
  e.stopPropagation();
});

    $('.Navigation-listItem').click(function () {
        $(this).children('.Navigation-list.is-dropdown').toggleClass('is-hidden');
    });


    /* Anything that gets to the document
   will hide the dropdown */
    $(document).on('click', function (event) {
        if ($(event.target).closest('#menu').length == false) {
            $(".Navigation-list.is-dropdown").addClass('is-hidden');
        }
    });

    /* Clicks within the dropdown won't make
   it past the dropdown itself */
    $(".Navigation-listItem.is-dropdown ").click(function (e) {
        e.stopPropagation();
    });
});

You can change the display property of your dropdown in this manner. This is just a rough code.

                       if(dropDownShow.css('display') != 'block'){
                            dropDownShow.css('display', 'block');
                            dropDownShow.css('position', 'absolute');

                        }
                        else{
                            dropDownShow.css('display', 'none');
                        }

有了您提供的信息和代码库，我看不到它起作用，但是我想隐藏的$（document）.click（function（）不会起作用，因为下拉列表位于文档内部，因此当您单击它时，我会建议您看这篇文章如何隐藏/显示HTML中的下拉列表内容 。
