html - 删除导航项下拉列表之间的空格，默认行为无法正常工作

Question

我正在尝试在应用程序的标题上添加 Bootstrap 菜单，几乎一切正常，但在 <nav> 上使用时<li class='nav-item dropdown'> ，它会添加一个空白空间并且不会在响应模式下折叠。

我在右侧添加了一个带有品牌的简单菜单，其结构如下:

>Menu
--Home
--Link
--Dropdown
---Action
---Another action
---Something else
--Another dropdown
---Action
---Another action
---Something else
--Disabled
>Brand

在桌面模式下，菜单正确显示。

尝试在 CSS 中编辑它们。

.nav-item{
    line-height: normal;
 }
