我希望手风琴菜单下拉并在点击子菜单时突出显示父级，对于点击的链接，下拉菜单应该保持打开状态，并突出显示父级。如果我单击父级没有子级的父级链接，则突出显示将位于父级。

Answer 1

要突出显示父级，请在CSS中添加名为highlight的类。

.highlight{
    box-shadow: inset 0 3px 3px 0px #fff,inset 0 9px 10px 0px #00abe3 !important;
}

现在，当单击任何特定父元素的子元素时，将添加此类。

$('.smenu > li>a').click( function() { 
                $(this).closest("ul").siblings('a').addClass('highlight');
            });

此外，此类将添加到没有子项的父级

if($(this).has('ul').length==0){
       $(this).children('a').addClass('highlight');
       }

这是一个演示小提琴：http://jsfiddle.net/rrh1c5d8/1/

P.S：根据您的需要改变突出显示的css。
