metronic.bootstrap 后台框架疑难点

metronic.bootstrap 对IE9 ，左侧菜单不能居于右侧，解决方案是在app.js里第241行添加代码

menu.parent().css({position:'absolute',left:'0px'});

 即如下：

 var handleFixedSidebar = function () {
        var menu = $('.page-sidebar-menu');
        if (menu.parent('.slimScrollDiv').size() === 1) { // destroy existing instance before updating the height
            menu.slimScroll({
                destroy: true
            });
            menu.removeAttr('style');
            $('.page-sidebar').removeAttr('style');            
        }
		
        if ($('.page-sidebar-fixed').size() === 0) {

//下面行是自己添加的
         	menu.parent().css({position:'absolute',left:'0px'});
            handleSidebarAndContentHeight();
            return;
        }
		
        if ($(window).width() >= 980) {
            var sidebarHeight = _calculateFixedSidebarViewportHeight();
			 
            menu.slimScroll({
                size: '7px',
                color: '#a1b2bd',
                opacity: .3,
                position: isRTL ? 'left' : ($('.page-sidebar-on-right').size() === 1 ? 'left' : 'right'),
                height: sidebarHeight,
                allowPageScroll: false,
                disableFadeOut: false
            });
            handleSidebarAndContentHeight();
        }
         
    }
