Bootstrap V4 collapsible Navbar alignment

问题

I got a question about BS4 and the alignment of a collapsible Menu.

Here is the Code I got:

<nav class="navbar navbar-light navbar-fixed-top">
  <div class="container">

    <button type="button" class="navbar-toggler hidden-sm-up pull-xs-right"
            data-toggle="collapse" data-target=".nav-content">
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Test</a>

    <div class="collapse navbar-toggleable-xs nav-content">
      <ul class="nav navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Leagues</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Login</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

Basic without

The Problem is, that I want to have the Menu Items (when not collapsed) aligned to the right and when collapsed, to the left side but below the Hamburger Button and the main nav. It worked fine with BS 3.

I've tried it with float-xs-right, but the it still doesn't work properly.

With float right

Kind regards, Chris

Depending on which version you're using of Bootstrap 4, the syntax has changed to float-**-right (See Responsive floats) as of the current v4.0.0-alpha.5, see this post under Utilities overhaul.

Another issue is when using a Responsive (float) utility against the navbar-toggler button, the list items will appear next the the navbar-brand instead of below it. As of right now I believe you have to handle this yourself by clearing the float within the correct breakpoint for your collapse.

Example CSS:

@media (max-width: 574px) {
    .navbar-header:after,
    .navbar-header:before {
        display: table;
        content: " "
    }
    .navbar-header:after {
        clear: both
    }
}

Working Example:

@media (max-width: 574px) {
  .navbar-header:after,
  .navbar-header:before {
    display: table;
    content: " "
  }
  .navbar-header:after {
    clear: both
  }
}

      <button class="navbar-toggler hidden-sm-up float-xs-right" type="button" data-toggle="collapse" data-target="#nav-content" aria-controls="nav-content" aria-expanded="false" aria-label="Toggle navigation"></button>
    </div>

    <div class="collapse navbar-toggleable-xs" id="nav-content">

      <ul class="nav navbar-nav float-sm-right">
        <li class="nav-item">
          <a class="nav-link" href="#">ABOUT</a>
