右侧的材料设计精简版（MDL）导航抽屉

Question

我正在将Google Material Design Lite（MDL）用于网络，因此无法将导航抽屉放在右侧。该文档没有有关如何执行此操作的信息。那有可能吗？

默认抽屉总是从左边来。

<header class="custom-header mdl-layout__header mdl-layout__header--waterfall">
    <div class="mdl-layout__drawer-button">
        <i class="material-icons">menu</i>
    </div>
    <div class="mdl-layout__header-row">
        <span class="mdl-layout-title">My App</span>
    </div>
</header>
<div class="mdl-layout__drawer">
    drawer contents...
</div>

Answer 1

实际上没有适当的方法来执行此操作，但是有一种解决方法。

首先，我们必须覆盖抽屉按钮的位置，然后再定位到整个抽屉，使其出现在右侧。然后，我们必须修复抽屉动画。

在您的style之后包括以下mdl-layout__header标签。

<header class="custom-header mdl-layout__header mdl-layout__header--waterfall">
    <div class="mdl-layout__header-row">
        <span class="mdl-layout-title">My App</span>
    </div>
</header>
<div class="mdl-layout__drawer">
    drawer contents...
</div>

<style>
    .mdl-layout__drawer-button, .mdl-layout__drawer{
        left: initial;
        right: 0;
    }

    .mdl-layout__drawer{    
        transform:translateX(250px);
    }
</style>
