Bootstrap 侧边栏在右侧展开

Question

我正在尝试水平扩展侧导航栏中的链接。 通过阅读引导程序 4 的教程，我已经很努力了。我的代码如下。

    <li class="active dropright">
        <a href="#homeSubmenu" data-toggle="collapse" aria-expanded="false" aria-haspopup="true" class="dropdown-toggle">
            <i class="fas fa-home"></i>
            Residential
        </a>
        <ul class="collapse list-unstyled" id="homeSubmenu">
            <li>
                <a href="#">Rami Villa</a>
            </li>
            <li>
                <a href="#">Alpine Metals Jafza</a>
            </li>
            <li>
                <a href="#">Home 3</a>
            </li>
        </ul>
    </li>

这段代码的结果如下。

当我单击住宅链接时，它的下拉列表如下。

但是我实际上想要这样的东西。

我对您的代码进行了一些修改，并按照您的要求完成了 output。

HTML


<aside>
  <li class="active dropright">
    <a href="#homeSubmenu" data-toggle="collapse" aria-expanded="false" aria-haspopup="true" class="dropdown-toggle">
      <i class="fas fa-home"></i>
      Residential
    </a>
    <ul class="collapse list-unstyled submenu" id="homeSubmenu">
      <li>
        <a href="#">Rami Villa</a>
      </li>
      <li>
        <a href="#">Alpine Metals Jafza</a>
      </li>
      <li>
        <a href="#">Home 3</a>
      </li>
    </ul>
  </li>

</aside>

CSS


ul,
li {
  list-style: none;
  padding: 0;
  margin: 0;
}

aside {
  width: 100%;
  height: 100%;
  max-width: 200px;
}
aside .dropright {
  position: relative;
  background: yellow;
}
aside .dropright a {
  padding: 10px;
  display: block;
}
aside .dropright .submenu {
  position: absolute;
  background: black;
  left: 100%;
  right: auto;
  width: 100%;
  top: 0;
}
aside .dropright .submenu li a {
  color: #fff;
  display: block;
}

我对编程很陌生，但是为什么不使用 Bootstrap 的示例：

像这样：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <!-- Default dropright button-->
    <div class="btn-group dropright">
      <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        Residential
      </button>
      <div class="dropdown-menu">
        <!-- Dropdown menu links-->
        <a class="dropdown-item" href="#">Rami Villa</a>
        <a class="dropdown-item" href="#">Alpine Metals Jafza</a>
        <a class="dropdown-item" href="#">Home 3</a>
      </div>
    </div>
  
    <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

Answer 3

您需要在<ul>上使用.dropdown-menu而不是.collapse

    <li class="active dropright">
      <a href="#homeSubmenu" data-toggle="collapse" aria-expanded="false" aria-haspopup="true" class="dropdown-toggle">
        <i class="fas fa-home"></i>
        Residential
      </a>
      <ul class="list-unstyled dropdown-menu" id="homeSubmenu">
        <li>
          <a href="#">Rami Villa</a>
        </li>
        <li>
          <a href="#">Alpine Metals Jafza</a>
        </li>
        <li>
          <a href="#">Home 3</a>
        </li>
      </ul>
    </li>
