如何防止 bootstrap 导航栏在折叠时分成几行

Question

我一直在搜索它一整天都找不到解决方案，所以我希望我不会看起来像个白痴，因为 2 分钟后有人会 post 回答 link 确切的问题。

我正在尝试创建一个类似于 steamdb 的导航栏导航栏折叠后搜索框保留的位置，只是尺寸缩小了。

但是我运行遇到了一个问题，如果我将导航栏设置为 <nav class="navbar-expand-lg" </nav> 然后当它折叠时它分成 3 行，一行用于 b运行d，一行用于搜索，一个用于切换下拉菜单。

如果我删除“-lg”，它就不会拆分，但它也不会更改要切换的项目。

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container">
      <a class="navbar-brand" href="/">My Company Name</a>
      <form class="d-flex w-100 d-inline-block">
        <div class="input-group">
          <input class="form-control no-border" type="text" placeholder="search for game..." id="example-search-input">
            <span class="input-group-append">
              <button class="btn rounded-pill" type="button">
              <i class="bi bi-search"></i>
              </button>
            </span>
        </div>
      </form>
      <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent"
        aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>

      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
          <li class="nav-item">
            <a class="nav-link active" aria-current="page" href="/">Home</a>
          </li>
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown"
              aria-expanded="false">
              content
            </a>
            <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
              <li><a class="dropdown-item" href="/test1">test1</a></li>
              <li><a class="dropdown-item" href="/test2">test2</a></li>
              <li><a class="dropdown-item" href="/test3">test3</a></li>
            </ul>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#">Donate</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

您需要在容器内使用 2 个内部 div。使它们都 w-100 和第一个 d-flex 以便品牌和表单水平布局...

  <nav class="navbar navbar-expand-lg navbar-light bg-light">
      <div class="container">
          <div class="d-flex w-100">
              <a class="navbar-brand" href="/">My Company Name</a>
              <form class="d-flex w-100 d-inline-block">
                  <div class="input-group">
                      <input class="form-control no-border" type="text" placeholder="search for game..." id="example-search-input">
                      <span class="input-group-append">
                          <button class="btn rounded-pill" type="button">
                              <i class="bi bi-search"></i>
                          </button>
                      </span>
                  </div>
              </form>
              <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                  <span class="navbar-toggler-icon"></span>
              </button>
          </div>
          <div class="collapse navbar-collapse w-100" id="navbarSupportedContent">
              <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                  <li class="nav-item">
                      <a class="nav-link active" aria-current="page" href="/">Home</a>
                  </li>
                  <li class="nav-item dropdown">
                      <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false"> content </a>
                      <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                          <li><a class="dropdown-item" href="/test1">test1</a></li>
                          <li><a class="dropdown-item" href="/test2">something</a></li>
                          <li><a class="dropdown-item" href="/test3">bla bla</a></li>
                      </ul>
                  </li>
                  <li class="nav-item">
                      <a class="nav-link" href="#">Donate</a>
