.page-header {
    padding-bottom: 9px;
    margin: 40px 0 20px;
    border-bottom: 1px solid #eee;
    display: flex;
    align-items: center;
    justify-content: space-between;
}

 <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

<div class="container">
  <div class="page-header">
    <h2>Header</h2>
    <div class="btn-group">
        <a class="btn btn-success" href="/Scope/New">Create</a>
        <div class="btn-group">
            <button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown">
                <span class="caret"></span>
            </button>
            <ul class="dropdown-menu pre-scrollable" role="menu">
                <li class="dropdown-header">Create as copy: </li>
                    <li><a href="/Scope/New/1">Test 1</a></li>
                    <li><a href="/Scope/New/2">Test 45</a></li>
                    <li><a href="/Scope/New/3">Lorem ipsum</a></li>
            </ul>
        </div>
    </div>
  </div>
</div>

就是这样，你可以使用 flex。
