Question

我想动态更改选中侧边栏上的按钮时显示在我的页面中的纸张选项卡。

即。 （选择要显示的标签）

专家| 3个标签

管理| 4个选项卡

等

我成功当我选择与问候到滚动对话框中显示的数据的标签本身获得的数据绑定工作，我只是停留在此。

页面tabs.html

<!-- THIS IS STILL A PRETTY BASIC EXAMPLE --> 
<paper-tabs selected="{{selected}}" noink> 
    <paper-tab link>

    </paper-tab> 
    <paper-tab link>

    <paper-tab link> 
     <a href="#tab3" tabindex="-1">TAB 3</a>

您可以<iron-pages>管理你的标签页，如

<iron-pages selected="[[page]]"> 
    <!-- Expert | 3 tabs --> 
    <page-tabs-expert></page-tabs-expert> 
    <!--- Admin | 4 tabs --> 
    <page-tabs-admin></page-tabs-admin> 
    <!-- etc. --> 
    <page-tabs-etc></page-tabs-etc> 
</iron-pages> 

而且，让你边栏中选择，能够与可能<iron-selector>，https://www.webcomponents.org/element/PolymerElements/iron-selector

<iron-selector selected={{page}}>
