这段代码是在uikit框架中编写的。我想删除那条多余的虚线，并且在将其更新时，手风琴项目也会相应地显示出来。

当我打开手风琴时，它会显示内容和虚线。当我添加更多手风琴项目时，除了所有这些项目之外，还会显示一条虚线。当我添加更多手风琴项目时，虚线没有响应，它仅显示了一半。我想使虚线响应（请参见图片）。我想那样做。

希望这就是您想要的。根据需要调整边距

li div.uk-accordion-content{
border-left: 3px dotted red;
margin-top:0 ;
margin-left:14px
}

$(document).ready(function(){
  $(".uk-accordion-title").click(function(){ 
  $(".itinerary-list-item").removeClass("show")
  $(this).parents(".itinerary-list-item").toggleClass("show");
  });
});

.itinerary-item-span-a::before{
                display: block;
              height: 30px;
              width: 30px;
              text-align: center;
              vertical-align: middle;
              border-radius: 50%;
              background:green ;
              color: #fff;
              line-height: 30px;
              z-index: 1;
              position: relative;
        }


li div.uk-accordion-content{
border-left: 3px dotted red;
margin-top:0 ;
margin-left:14px
}

.uk-accordion li:last-child .uk-accordion-content{
border-left: none}

.uk-accordion li:before{
      content: "";
    border-left: 3px dotted red;
    position: absolute;
    /* top: 0; */
    width: 100px;
    height: 44px;
    left: 14px;
    /* bottom: 0px; */
    transform: translateY(0px);

}

.uk-accordion li.show:before{
display:none}

.uk-accordion li{position:relative}
