Bootstrap 5 导航栏菜单右侧

在Bootstrap 5中，导航栏菜单右侧是一个重要的部分，可以放置各种元素，例如按钮、下拉列表等。本文将介绍如何在Bootstrap 5中实现导航栏菜单右侧的设计。

添加内容

可以通过在 navbar 中添加 .navbar-nav、.ms-auto 和 .me-3 类，来使导航栏菜单右侧对齐并与菜单栏分隔开。以下是示例代码：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">Brand</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      
      <!-- 右侧内容 -->
      <ul class="navbar-nav ms-auto me-3">
        <li class="nav-item">
          <a class="nav-link" href="#">Sign in</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Sign up</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

添加按钮

如果需要在导航栏菜单右侧添加按钮，可以在上一步骤基础上进行扩展。以下示例代码将在右侧添加一个按钮：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">Brand</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      
      <!-- 右侧内容 -->
      <ul class="navbar-nav ms-auto me-3">
        <li class="nav-item">
          <a class="nav-link" href="#">Sign in</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Sign up</a>
        </li>
        
        <!-- 添加按钮 -->
        <li class="nav-item">
          <button class="btn btn-primary" type="button">Get started</button>
        </li>
      </ul>
    </div>
  </div>
</nav>

添加下拉列表

如果需要在导航栏菜单右侧添加下拉列表，可以使用Bootstrap中的 dropdown 类实现。以下示例代码将在右侧添加一个下拉列表：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">Brand</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      
      <!-- 右侧内容 -->
      <ul class="navbar-nav ms-auto me-3">
        <li class="nav-item">
          <a class="nav-link" href="#">Sign in</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Sign up</a>
        </li>
        
        <!-- 添加下拉列表 -->
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Menu
          </a>
          <div class="dropdown-menu" aria-labelledby="navbarDropdown">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <div class="dropdown-divider"></div>
            <a class="dropdown-item" href="#">Something else here</a>
          </div>
        </li>
      </ul>
    </div>
  </div>
</nav>
