Bootstrap 4 alpha 6 nav-tabs对齐项目

Question

我正在尝试创建一个菜单中最右边有nav-item dropdown的选项卡菜单。

Bootstrap 4 alpha 5，float-xs-right工作：http://codeply.com/go/FCFPpRqhZd

Bootstrap 4 alpha 6，我改为qazxsw poi但它不起作用：qazxsw poi

有想法吗？

Answer 1

由于alpha 6现在是flexbox，float-right将不再适用于这种情况。

使用http://codeply.com/go/5mddDUv1M6实用程序类代替float

ml-auto

margin-left:auto

Answer 2

如果要在导航栏中右对齐多个项目，可以使用一个示例：

<div class="col-md-12">
    <ul class="nav nav-tabs">
        <li class="nav-item">
            <a href="#" class="nav-link active">Link 1</a>
        </li>
        <li class="nav-item">
            <a href="#" class="nav-link">Link 2</a>
        </li>
        <li class="nav-item">
            <a href="#" class="nav-link">Link 3</a>
        </li>
        <li class="nav-item">
            <a href="#" class="nav-link">Link 4</a>
        </li>
        <li class="nav-item dropdown ml-auto">
            <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Account</a>
            <div class="dropdown-menu">
                <a class="dropdown-item" href="#">Action</a>
                <a class="dropdown-item" href="#">Another action</a>
                <a class="dropdown-item" href="#">Something else here</a>
                <div class="dropdown-divider"></div>
                <a class="dropdown-item" href="#">Separated link</a>
            </div>
        </li>
    </ul>
</div>

这里可以找到一个例子：http://www.codeply.com/go/hhV1aM49zz。

这里的技巧是在第一个元素（从左到右）上设置

<div class="container py-3">
    <div class="col-10 mx-auto">
        <ul class="nav nav-tabs small" role="tablist">
            <li class="nav-item"><a class="nav-link active" data-toggle="tab" href="#tab11" role="tab">First</a></li>
            <li class="nav-item ml-auto"><a class="nav-link" data-toggle="tab" href="#tab22" role="tab">More</a></li>
            <li class="nav-item"><a class="nav-link" data-toggle="tab" href="#tab33" role="tab">More 2</a></li>
        </ul>
        <div class="tab-content py-4">
            <div class="tab-pane active" id="tab11" role="tabpanel">
                <h2 class="mb-3">Right Align Individual Tabs</h2>
                <p>The above tabs use `ml-auto` to right align indiviual tabs</p>

            </div>
            <div class="tab-pane" id="tab22" role="tabpanel">
                <div class="card border-primary mb-3">
                    <div class="card-body">
                        <h3 class="card-title">Primary</h3>
                        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
                        <a href="#" class="btn btn-outline-secondary">Outline</a>
                    </div>
                </div>
                <div class="card border-primary mb-3">
                    <div class="card-body">
                        <h3 class="card-title">Primary</h3>
                        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
                        <a href="#" class="btn btn-outline-secondary">Outline</a>
                    </div>
                </div>
            </div>
            <div class="tab-pane" id="tab33" role="tabpanel">
                More..
            </div>
        </div>
    </div>
</div>

类，只想在右边对齐。
