移动导航项目和下拉菜单的困难[重复]

Question

我设计了一个包含导航项、下拉按钮、下拉菜单的导航栏 商品未在展示中显示，这就是它的样子

我使用 margin-left 来移动注册导航项，认为它会移出，但它没有响应可以提供哪些其他解决方案？我的代码是...

<div class="collapse navbar-collapse" id="navbarSupportedContent">       
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current) 
   </span></a> 
</li>
<li class="nav-item active">
<a class="nav-link" href="#">About Us <span class="sr-only"> 
(current)</span></a>
</li> 
<li class="nav-item active">
<a class="nav-link" href="#">Contact Us <span class="sr-only"> 
(current)</span></a>
</li>              
</ul>  
<ul class="nav navbar-nav navbar-right">
<li class="nav-item">
<a class="nav-link" href="#">Sign-Up</a>
