html - 想要在右上角出现菜单图标按钮。在 Material Design Lite 中

Question

我想移动右上角的菜单图标按钮。但它出现在标题下。 我应该添加什么样的属性？

    <!-- Simple header with fixed tabs. -->
<div class="mdl-layout mdl-js-layout mdl-layout--fixed-header
            mdl-layout--fixed-tabs">
  <header class="mdl-layout__header">
    <div class="mdl-layout__header-row">
      <!-- Title -->
      <span class="mdl-layout-title">Title</span>
    </div>
    <!-- Right aligned menu below button -->

<button id="demo-menu-lower-right"
        class="mdl-button mdl-js-button mdl-button--icon">
  <i class="material-icons">more_vert</i>
</button>

<ul class="mdl-menu mdl-menu--bottom-right mdl-js-menu mdl-js-ripple-effect"
    for="demo-menu-lower-right">
  <li class="mdl-menu__item">Some Action</li>
  <li class="mdl-menu__item">Another Action</li>
  <li disabled class="mdl-menu__item">Disabled Action</li>
  <li class="mdl-menu__item">Yet Another Action</li>
</ul>
    <!-- Tabs -->
    <div class="mdl-layout__tab-bar mdl-js-ripple-effect">
      <a href="#fixed-tab-1" class="mdl-layout__tab is-active">Tab 1</a>
      <a href="#fixed-tab-2" class="mdl-layout__tab">Tab 2</a>
      <a href="#fixed-tab-3" class="mdl-layout__tab">Tab 3</a>
      <a href="#fixed-tab-4" class="mdl-layout__tab">Tab 4</a>
    </div>
  </header>

要使菜单显示在右侧，您需要在 mdl-layout__header-row 元素中添加以下 div ，然后添加您想要的任何元素头部的右侧。请参阅 Layout 上的 Material Design Lite更多细节。

<div class="mdl-layout mdl-js-layout">
  <header class="mdl-layout__header mdl-layout__header--transparent">
    <div class="mdl-layout__header-row">
      <!-- Title -->
      <span class="mdl-layout-title">Title</span>

      <!-- Add spacer, to align navigation to the right -->
      <div class="mdl-layout-spacer"></div>

      <!-- Navigation -->
      <nav class="mdl-navigation">
        <a class="mdl-navigation__link" href="">Link</a>
        <a class="mdl-navigation__link" href="">Link</a>
        <a class="mdl-navigation__link" href="">Link</a>
        <a class="mdl-navigation__link" href="">Link</a>
      </nav>

      <!-- Right Menu -->
      <button id="demo-menu-lower-right"
              class="mdl-button mdl-js-button mdl-button--icon">
        <i class="material-icons">more_vert</i>
      </button>

      <ul class="mdl-menu mdl-menu--bottom-right mdl-js-menu mdl-js-ripple-effect"
          for="demo-menu-lower-right">
        <li class="mdl-menu__item">Some Action</li>
        <li class="mdl-menu__item">Another Action</li>
        <li disabled class="mdl-menu__item">Disabled Action</li>
        <li class="mdl-menu__item">Yet Another Action</li>
      </ul><!--/Right Menu -->
    </div>
  </header>
  <div class="mdl-layout__drawer">
    <span class="mdl-layout-title">Title</span>
    <nav class="mdl-navigation">
      <a class="mdl-navigation__link" href="">Link</a>
      <a class="mdl-navigation__link" href="">Link</a>
      <a class="mdl-navigation__link" href="">Link</a>
      <a class="mdl-navigation__link" href="">Link</a>
    </nav>
  </div>
  <main class="mdl-layout__content">
  </main>
</div>

另外，如果你想改变Menu的位置，可以把mdl-menu--bottom-right改成你喜欢的方向。请引用MDL Menu页面底部的规范。
