带有输入字段的输入组，选择（silviomoreto）和按钮未正确显示

Question

我目前有一个输入组，由一个输入字段、一个选择菜单和一个按钮组成。

我知道您必须使用下拉菜单而不是在引导程序中选择，但我想避免在 javascript 中使用下拉菜单。

我使用的选择菜单来自：https://silviomoreto.github.io/bootstrap-select/examples/，所以它不是引导版本，但是我在这里使用引导选择来回答这个问题。

目前选择菜单位于输入字段下方，我不确定它为什么这样做，但我希望输入组位于一行。

我不想给选择一个特定的宽度，因为那行不通，我已经尝试过了，它只会产生问题，所以如果可以的话，我希望它采用默认宽度。

有什么想法吗？

据我所知，您必须自己执行此操作，我认为 Bootstrap 中不支持使用按钮对多个输入字段进行分组。

其中绝大多数是基于视口定义每个输入的边界半径，因为它们被放置在列内（*也移除了填充以将输入保持在一起）。

以下是三个示例，具体取决于您可能希望或不希望如何在不同设备上处理此问题。

（*确保将片段打开到整页，然后缩小浏览器以查看更改）

工作示例：

$('.select-group').selectpicker();

/**CSS BELOW THIS LINE IS FOR EXAMPLE ONLY: NOT RELEVANT TO ANSWER**/

body {
  padding-top: 20px;
}
.the-form,
.the-form-2,
.the-form-3 {
  padding: 0 15px;
}
/**CSS ABOVE THIS LINE IS FOR EXAMPLE ONLY: NOT RELEVANT TO ANSWER**/

.no-gutter > [class*='col-'] {
  padding-right: 0;
  padding-left: 0;
}
/**FORM 1**/

@media (min-width: 768px) {
  .the-form .form-control.new-form-control {
