小型设备上的Bootstrap 4菜单

Question

笔记本电脑或台式机上的菜单就像我想要的那样，但是在小屏幕上，我正在“丢失”选项；搜索图标和翻译菜单。我想要实现的是徽标，搜索图标，翻译栏和汉堡菜单相互对齐。另外，徽标和汉堡菜单下方第二行的输入字段也可以使用。

到目前为止，我一直在使用各种Bootstrap导航栏组件，但没有设法正确使用它。在下面的代码中，也使用了一些技巧，但我认为这对解决方案没有任何影响。

希望有人可以向我指出正确的方向，以使其更进一步。

谢谢！

根据添加一些HTML的请求，首先添加标题：

<div class="page-header page-header-small">
            <div class="page-header-image" style="background-image: url('data:image/jpeg;base64,.........;">
  </div>
  <div class="content-center">
    <div class="row">
      <div class="col-md-8 ml-auto mr-auto">
        <div class="rellax" data-rellax-speed="-3" style="transform: translate3d(0px, 0px, 0px);">
          <h1 class="title">Downloads</h1>
        </div>
        <h4>
            Downloaden van (technische) bootdocumenten
        </h4>
        <nav aria-label="breadcrumb" role="navigation">
          <nav aria-label="breadcrumb">
            <ol class="breadcrumb">
              <li class="text-info">U bent hier:&nbsp;</li>
                                        <li class="breadcrumb-item">
                <a href="https://develop.some-site.eu/" title="Home">
                  Home
                </a>
                </li>
                <li class="breadcrumb-item">
                    <a href="#" title="Links">Links</a>
                </li>
                <li class="breadcrumb-item active" aria-current="page">Downloads</li>
           </ol>
          </nav>
        </nav>
      </div>
    </div>
  </div>
</div>

以及在小屏幕模式下菜单中的代码

在开发环境中，如果您调整大小，您会明白我的意思并尝试实现development site
