html - Bootstrap nav-tabs 下拉菜单多列

Question

我正在尝试为导航选项卡创建一个 Bootstrap 多列下拉菜单。使用下面的代码，我可以选择每个选项卡。当我切换到另一个选项卡时，我无法返回到之前的选项卡。看起来所有选项卡都保持事件状态。我该如何解决这个问题？

将其添加到底部

 <script type="text/javascript">
        $(function() {

        var active = $('a[data-toggle="tab"]').parents('.active').length;
        var tabClicked = false;

        // Closes current active tab (toggle and pane):
        var close = function() {
            $('a[data-toggle="tab"]').parent().removeClass('active');
            $('.tab-pane.active').removeClass('active');
            active = null;
        }

        // Closing active tab when clicking on toggle:
        $('[data-toggle=tab]').click(function(){
            if ($(this).parent().hasClass('active')){
                $($(this).attr("href")).toggleClass('active');
                active = null;
            } else {
                tabClicked = true;
                active = this;
            }
        });

        // Closing active tab when clicking outside tab context (toggle and pane):
        $(document).on('click.bs.tab.data-api', function(event) {
            if(active && !tabClicked && !$(event.target).closest('.tab-pane.active').length) {
                close();
            }

            tabClicked = false;
        });

        // Closing active tab on ESC key release:
        $(document).keyup(function(e){
            if(active && e.keyCode === 27) { // ESC
                close();
            }
        });
    });

        </script>
