【问题描述】：
我试图为我的问题寻找答案，但我似乎找不到答案。如果有任何机会确实有解决方案，那么，对不起，我的错！
我似乎遇到了 Bootstrap 的默认导航栏的问题：下拉菜单：.navbar-right 由于某种原因向左浮动。您可以查看here。
我正在使用 rails 5，我的导航代码目前看起来像：
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<%= link_to "Prodemex", root_path, class: "navbar-brand", id: "logo" %>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li><%= link_to "Articulos", articles_path %></li>
<li><%= link_to "Usuarios", users_path %></li>
<% if logged_in? %>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Actions <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><%= link_to "Nuevo articulo", new_article_path %></li>
<li role="separator" class="divider"></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
<% end %>
<form class="navbar-form navbar-left">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
<% if logged_in? %>
<ul class="nav navbar-nav navbar-right">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="true">Mi cuenta<%= " - Admin " if current_user.admin? %><span class="caret"></span></a>
<ul class="dropdown-menu">
<li><%= link_to "Modificar mis datos", edit_user_path(current_user) %></li>
<li><%= link_to "Ver mi perfil", user_path(current_user) %></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><%= link_to 'Cerrar sesión', logout_path, method: :delete %></li>
</ul>
</li>
</ul>
<% else %>
<ul class="navbar-right nav navbar-nav">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="true">Mi cuenta <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><%= link_to 'Iniciar sesión', login_path %></li>
<li><%= link_to 'Registrarse', signup_path %></li>
</ul>
</li>
</ul>
<% end %>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
您可以在github 上检索更多代码 我有一个包含所有内容的自定义 CSS，并且已经尝试删除与导航栏相关的所有部分，但它什么也没做......

box-shadow: 4px 1px 10px 0px rgba(50, 50, 50, 0.27);
}
奇怪的是，当我登录时，下拉菜单又回到了它应该在的右边...... 检查代码时，我几乎找到了一个修复，删除了这部分的左浮动：
@media (min-width: 768px)
custom.self-839…ss?body=1:5864
.navbar-nav {
float: left;
margin: 0;
}
但很明显，当我这样做时，它会与导航栏的其余部分混淆。 任何机构可以帮助我？提前致谢！！
