将下拉列表菜单添加到列表项 CSS

如何解决将下拉列表菜单添加到列表项 CSS

我想在我的导航栏中的第四个元素中添加一个下拉列表。 在“ESPACE PARTICULIER”下，我需要获得 2 个选项。

<div class="collapse navbar-collapse" id="navbarSupportedContent">
  <ul class="navbar-nav ml-auto">
    <li class="nav-item active">
      <a class="nav-link" href="#">A PROPOS NOUS</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">COURS</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">SERVICES</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">ESPACE PARTICULIER</a>
    </li>
    <li class="nav-item">
      <a class="button-highlight" href="#">Sign in</a>
    </li>
  </ul>
</div>

解决方法

您正在使用 Bootstrap，因此很容易做到这一点，请查看此 Bootstrap Dropdown

<div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav ml-auto">
        <li class="nav-item active">
          <a class="nav-link" href="#">A PROPOS NOUS</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">COURS</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">SERVICES</a>
        </li>
        <li class="nav-item dropdown">
        
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown"role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">ESPACE PARTICULIER</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>
        <li class="nav-item">
          <a class="button-highlight" href="#">Sign in</a>
        </li>
      </ul>
    </div>
