如何一次只打开一个子菜单

Question

我做了响应式菜单。这工作正常。

但问题是这个。我想一次打开一个菜单。

打开一个子菜单时应该隐藏另一个菜单吗？

我该怎么做？

这是我的脚本代码

$('.moremain').click(function(){
    $(this).next('.hrmenu ul ul').slideToggle();
    $(this).toggleClass("active");
});

这是My Menu

这是一个有效的演示。

$(document).ready(function(){

	$('.hrmenu > ul').before("<span class='main'></span>");	
	$('.hrmenu ul ul').before("<span class='moremain'></span>");	
	
	

	
	$('.main').click(function(){
		
		$('.hrmenu > ul').slideToggle();
	});
	
	$('.moremain').click(function(){
		
		
		$(this).next('.hrmenu ul ul').slideToggle();
        $(this).parents('li').eq(0).siblings().each(function(){
        var _toggle = $(this).find('.moremain').eq(0);
            if(_toggle.hasClass("active")){
                 _toggle.removeClass("active");
                 $(this).find('ul').eq(0).slideToggle();
            }
       
        });
		$(this).toggleClass("active");
	});
	
	
	$(window).resize(function(){
		
		if(window.screen()> 1000)
		{
			$('.hrmenu ul').show();
		}
	});
	
	
});

               	<ul>
                   <li><a href='#'>Sub Product</a></li>
                   <li><a href='#'>Sub Product</a></li>                    </ul>
               </li>
               <li><a href='#'>Sub Product</a></li>
            </ul>
         </li>
      </ul>
   </li>
   <li><a href='#'>About</a></li>
   <li><a href='#'>Contact</a></li>
</ul>
</div>

说明：对于每个slibling li，如果其moremain toggle具有活动类，则切换其第一个ul。

这就是你要找的东西

$(".hr-nav-wrapper").hrNavMenu({ 
        speed:800, //integer in milliseconds  1000,2000
        menuType :"fromLeft", //fromLeft, fromTop
        desktopListWidth : "fluid", // fluid, default
        openEvent : "click", //click, mouseover
        multiple  : false // true, false

    });

只需使用css

，您就不需要使用javascript来执行下拉菜单

/*rules for all li elements*/
li{
    position:relative;/*allow submenu to use the position of its parent as reference */
    display:inline-block;
    padding:5px;
}

/*rules for only submenu li elements*/

/*submenus are displayed only when its li parent is hovered*/
li > ul{
    display:none;
    position:absolute;
}
li:hover > ul{
    display:block;
}

/*submenus of submenus are displayed at the right of their parent and on the same abscisse*/
li li:hover > ul{
    left:100%;
    top:0;
}

*{margin:0px;padding:0px;color:#fff}
ul{ list-style-type:none;}
a{ white-space: nowrap;}

.hrmenu ul{background:#06C;}
.hrmenu ul ul {background:#aaf;}
.hrmenu ul ul ul {background:#06C;}
.hrmenu ul ul ul ul {background:#aaf;}

/*rules for all li elements*/
li{
    position:relative;/*allow submenu to use the position of its parent as reference */
    display:inline-block;
    padding:5px;
}

/*rules for only submenu li elements*/

/*submenus are displayed only when its li parent is hovered*/
li > ul{
    display:none;
    position:absolute;
}
li:hover > ul{
    display:block;
}

/*submenus of submenus are displayed at the right of their parent and on the same abscisse*/
li li:hover > ul{
    left:100%;
    top:0;
}

<div class='hrmenu'>
