This article mainly introduces how to implement the accordion menu based on Jquery Code. The Code is simple and easy to understand. For more information, see:

First look at the page code, nesting of the list:

  

        
  •       B      
              
    • C
    •         
    • C
    •         
    • C
    •       
        
  •     
  •       B      
              
    • C
    •         
    • C
    •         
    • C
    •       
        
  •     
  •       B      
              
    • C
    •         
    • C
    •         
    • C
    •       
        
  •   

Css code, mainly set the background color and the Left Border style of the sub-menu, set the floating and selected style, and start to set the sub-menu not to display (click through js settings and then display ):

#menuDiv{  width: 200px;  background-color: #029FD4;}.parentLi{  width: 100%;  line-height: 40px;  margin-top: 1px;  background: #1C73BA;  color: #fff;  cursor: pointer;  font-weight:bolder;}.parentLi span{  padding: 10px;}.parentLi:hover, .selectedParentMenu{  background: #0033CC;}.childrenUl{  background-color: #ffffff;  display: none;}.childrenLi{  width: 100%;  line-height: 30px;  font-size: .9em;  margin-top: 1px;  background: #63B8FF;  color: #000000;  padding-left: 15px;  cursor: pointer;}.childrenLi:hover, .selectedChildrenMenu{  border-left: 5px #0033CC solid;  background: #0099CC;  padding-left: 15px;}

Next, click the Event code:

$(".parentLi").click(function(event) {    $(this).children('.childrenUl').slideToggle();  });  $(".childrenLi").click(function(event) {    event.stopPropagation();    $(".childrenLi").removeClass('selectedChildrenMenu');    $(".parentLi").removeClass('selectedParentMenu');    $(this).parents(".parentLi").addClass('selectedParentMenu');    $(this).addClass('selectedChildrenMenu');  });

It should be noted that the list nesting will cause event bubbling, so the click event in the sub-menu should organize the bubbling event. stopPropagation ();

The above code is simple. The code is a comment, and the jquery accordion menu is implemented. For more information, see.
