Bootstrap 4导航栏/菜单在折叠时保持可见

这是与此类似的问题，但这是针对Bootstrap 4的。

我无法在BS4导航栏上添加右对齐条目，这些条目在折叠和未折叠时都保持可见。我整整一个下午都没有成功。

这是我的目标：

这是我当前的代码（仅在未折叠时有效）：

<nav class="navbar navbar-light navbar-expand-xl border-bottom mainmenu sticky-top">
    <a class="navbar-brand text-capitalize text-blur" href="/">
        <img class="mr-1" src="/images/logo/favicon-32x32.png" alt="Logo">
        <span class="">Portami in Pista</span>
    </a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#myTopMenu"
        aria-controls="collapsableTopMen" aria-expanded="false" aria-label="[Menu]">
        <span class="sr-only">[Menu]</span>
        <span class="navbar-toggler-icon" title="[Menu]"/>
    </button>

    <div class="collapse navbar-collapse" id="collapsableTopMen">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item">
                <a class="nav-link" href="/Schools/">
                    <i class="fa fa-motorcycle fa-rotate-315 text-danger" aria-hidden="true"/>
                    <span class="text-blur-danger">PiP Reparto Corse</span>
                </a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/Tracks/">
                    <i class="fa fa-flag-checkered text-primary" aria-hidden="true"/>
                    <span>Piste</span>
                </a>

                </a>
            </li>
        </ul>
        <ul class="navbar-nav ml-auto">
            <!- START of section should be always visible -->
            <li class="nav-item dropdown">

                    <span class="d-inline d-xl-none">Italiano</span>

                    </a>
                </div>
            </li>
            <!- END of section should be always visible -->

            <li class="nav-item">
                <a class="nav-link" href="/Account/Login"><i class="fa fa-sign-in"/> Log in</a>
            </li>
        </ul>
    </div>
</nav>

由于您使用的是Bootstrap 4，因此此答案与您的问题更相关：

您始终希望保持可见的部分需要与任何可折叠部分分开。然后使用这些order-*类按需放置项目：
