Bootstrap 4 Alpha 6. 导航栏折叠时搜索框溢出容器答案

【问题标题】：Bootstrap 4 Alpha 6. Searchbox overflows container on navbar collapseBootstrap 4 Alpha 6. 导航栏折叠时搜索框溢出容器

【问题描述】：

我是相当新的 Bootstrap 4，所以这里可能有很多错误。

我想创建一个响应式导航栏，它可以折叠我的 4 个菜单按钮，但仍将搜索栏保持在其右侧。我还不确定如何处理展开后按钮的显示，但我现在的目标是将搜索栏保持在正确的宽度。

当屏幕变“小”时，导航切换按钮会出现，折叠菜单按钮。这很酷。但是搜索栏只是从它所在的容器中长出来的。如何将其保留在容器中？

感谢任何建议和改进:)

nav {
  background: brown;
}

nav .container {
  white-space: nowrap;
}

编辑：我稍微调整了一下，得到了以下结果 -> https://jsfiddle.net/Taliesin84/qL35nejo/

我当前的目标是防止搜索栏在尺寸太小时包裹在折叠按钮的下方。我还需要在更大的屏幕尺寸下使搜索栏更宽，但目前这是次要的。有什么新想法吗？

【解决方案1】：

来自 Bootstrap 4 的 github repo 中包含的示例：

<form class="form-inline my-2 my-lg-0">
  <input class="form-control mr-sm-2" type="text" placeholder="Search">
  <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>

【讨论】：

不幸的是，这不起作用。折叠菜单项后，搜索框将换行到下面的一行:(
