html - 第二个位置绝对包装器的行为与第一个不同

标签 html css bootstrap-4

我准备了一个 css，其中相同的样式在一个案例中按预期工作，而进一步，嵌套导航不再。

我的目标是在下拉菜单下方显示导航。

该应用程序用于引导 4，但导航非常自定义

.nav-center-nested 与 first nested nav 和 second nested nav 一起使用 - 但与第二个相同style(相同的html)工作方式不同

问题 当我将 kuguar-sport-color 添加到嵌套导航时，如何将嵌套导航从右侧移动到下拉列表的底部 - 颜色剂量工作

谢谢!

最佳答案

我已将嵌套子菜单移动到 nav-btn-margin 内的相对位置。还为子菜单添加了 inner-dropdown 类。

尝试此解决方案并发表评论以获得进一步的帮助。
