如果你想要首页，功能和定价在左侧紧跟着你的nav-brand，然后登录和注册在右侧，然后包装两个列表在<div>和使用.justify-content-between:

<div class="collapse navbar-collapse justify-content-between">
<ul>....</ul>
<ul>...</ul>
</div>

在bootstrap v4.3中，只需在<ul class="navbar-nav">中添加ml-auto 示例:<ul class="navbar-nav ml-auto">

我是栈溢出的新手，也是前端开发的新手。这对我来说很管用。所以我不希望显示列表项。

.hidden { display:none; } #loginButton{ margin-right:2px; } <nav class="navbar navbar-toggleable-md navbar-light bg-faded fixed-top"> <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <a class="navbar-brand" href="#">NavBar</a> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav mr-auto"> <li class="nav-item active hidden"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item hidden"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item hidden"> <a class="nav-link disabled" href="#">Disabled</a> </li> </ul> <form class="form-inline my-2 my-lg-0"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit" id="loginButton"><a href="#">Log In</a></button> <button class="btn btn-outline-success my-2 my-sm-0" type="submit"><a href="#">Register</a></button> </form> </div> </nav>

使用flex-row-reverse类

<nav class="navbar navbar-toggleable-md navbar-light">
    <div class="container">
        <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false"
          aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <a class="navbar-brand" href="#">
            <i class="fa fa-hospital-o fa-2x" aria-hidden="true"></i>
        </a>
        <div class="collapse navbar-collapse flex-row-reverse" id="navbarNavAltMarkup">
            <ul class="navbar-nav">
                <li><a class="nav-item nav-link active" href="#" style="background-color:#666">Home <span class="sr-only">(current)</span></a</li>
                <li><a class="nav-item nav-link" href="#">Doctors</a></li>
                <li><a class="nav-item nav-link" href="#">Specialists</a></li>
                <li><a class="nav-item nav-link" href="#">About</a></li>
            </ul>
        </div>
    </div>
</nav>

在我的案例Bootstrap v5中，我只想在右侧设置一组导航选项:

只需在ul中添加“ms-auto”即可。

它帮助了我。

<div class="collapse navbar-collapse" id="navbarCollapse">
    <ul class="navbar-nav ms-auto mb-2 mb-md-0">
      <li class="nav-item">
        <a class="nav-link " aria-current="page" href="index.php">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link " href="services.php" tabindex="-1" aria-disabled="true">Services</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="aboutus.php">About Us</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="Portfolio.php">Portfolio</a>
      </li>
    </ul>
    
  </div>

只需在ul中添加mr-auto类:

<ul class="nav navbar-nav mr-auto">

如果你在两边都有菜单列表，你可以这样做:

<ul class="navbar-nav mr-auto">
  <li class="nav-item active">
    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#">Disabled</a>
  </li>
</ul>
<ul class="navbar-nav ml-auto">
  <li class="nav-item active">
    <a class="nav-link" href="#">left 1</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">left 2</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#">left disable</a>
  </li>
</ul>
