Question

所以我正在为一个移动友好网站开发Sidenav。我在侧边栏中有一个可操作的，多级可维护的下拉菜单。

我希望下拉菜单可以像在手风琴菜单中一样按下它们下面的链接，而不是重叠所说的链接。

我已经看过其他解决方案了，但是我无法绕过它们。

提前感谢您的帮助！

这是我目前的菜单代码：

＆＃13;

function openNav() {
  document.getElementById("mySidenav").style.width = "20%";
}

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
}

＆＃13;

  body {
  font-family: Centaur;
}

.sidenav {
  height: 100%;
  width: 0;
  position: fixed;
  z-index: 1;
  top: 0;
  right: 0;
  background-color: black;
  overflow-x: hidden;
  transition: 0.5s;
  padding-top: 60px;
}

.sidenav a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #818181;
  display: block;
  transition: 0.3s;
}

.sidenav a:hover {
  color: #f1f1f1;
}

.sidenav .closebtn {
  position: absolute;
  top: 0;
  right: 25px;
  font-size: 36px;
  margin-left: 50px;
}

@media screen and (max-height: 450px) {
  .sidenav {
    padding-top: 15px;
  }
  .sidenav a {
    font-size: 18px;
  }
  .dropbtn {
    background-color: transparent;
    padding: 2%;
    font-size: 100%;
    border: none;
    cursor: pointer;
  }
  .dropdown {
    position: relative;
    display: inline-block;
  }
  .dropdown1 {
    position: relative;
    display: inline-block;
  }
  .dropdown-content {
    display: none;
    position: absolute;
    right: 0;
    min-width: 160px;
    z-index: 1;
  }
  .dropdown-content1 {
    display: none;
    position: absolute;
    right: 0;
    min-width: 160px;
    z-index: 1;
  }
  .dropdown-content1 a {
    text-decoration: none;
    display: block;
  }
  .dropdown-content a {
    text-decoration: none;
    display: block;
  }
  .dropdown1:hover .dropdown-content1 {
    display: block;
  }
  .dropdown:hover .dropdown-content {
    display: block;
  }

＆＃13;

<div id="mySidenav" class="sidenav">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
  <div style="width: 15%" id="navtaner">
