是否可以在标签中创建标签？上面最简单的例子（原谅嵌套）并没有真正起作用，“子标签”将无法正确呈现。标签不起作用，内容不显示。
简短回答 - 是的。
我有同样的问题，并且没有任何问题让这个工作：

<md-content class="md-padding">
<md-tabs md-dynamic-height md-stretch-tabs>
<md-tab label="Top Level 1">

干杯，丹
请注意，Material Design中明确不支持嵌套选项卡。请参阅Material Design - Tabs component的最后一个例子或这个github讨论：setting class on nested tabs
你应该考虑另一种方法！
