I want to add a dropdown menu to my navbar but the menu is always out of the page.我想在我的导航栏中添加一个下拉菜单，但菜单总是在页面之外。

Here is my code:这是我的代码：

 <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.0.0/dist/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <nav class="navbar navbar-dark bg-dark"> <a class="navbar-brand" href="#">PEL</a> <div class="btn-group"> <button type="button" class="btn btn-secondary dropdown-toggle mr-3" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">${pseudo}</button> <div class="dropdown-menu dropdown-menu-right"> <button class="dropdown-item dropdown-menu-right" type="button">Action</button> <button class="dropdown-item dropdown-menu-right" type="button">Another action</button> <button class="dropdown-item dropdown-menu-right" type="button">Something else here</button> </div> </div> </nav>

Dropdown works good but it is always out of the right side of my screen...下拉菜单效果很好，但它总是在我屏幕的右侧之外......

A little space is created by my dropdown menu on the right side of the page.我在页面右侧的下拉菜单创建了一个小空间。

According to the v4.0 doc:根据 v4.0 文档：

https://getbootstrap.com/docs/4.0/components/dropdowns/#menu-alignment https://getbootstrap.com/docs/4.0/components/dropdowns/#menu-alignment

Heads up.小心。 Dropdowns are positioned thanks to Popper.js ( except when they are contained in a navbar ).下拉菜单的位置得益于 Popper.js（除非它们包含在导航栏中）。

Two options:两种选择：

Upgrade your bootstrap version.升级您的引导程序版本。 It's working fine with v4.6它在 v4.6 上运行良好
Use custom classes instead of bootstrap navbar使用自定义类而不是引导导航栏

[EDIT 1] Here is a working example with bootstrap v4.6. [编辑 1] 这是一个使用 bootstrap v4.6 的工作示例。 Also i have removed the mr-3 class for better rendering.我还删除了mr-3 class 以获得更好的渲染效果。
