我是聚合物的新手，基于入门工具包1.3.0，默认情况下，在桌面视图上显示如下：
Desktop View（带toggle menu按钮）
在手机上：
Mobile View（toggle menu按钮丢失！）
如何强制网页在桌面视图上显示toggle menu按钮？
这是index.html，只是入门套件的默认设置，完全没有变化。

答案 0 :(得分：0)
在app-theme.html中添加此css：
#paperToggle {
display: inline-block !important;
}
在app.js的底部添加：
app.toggleDrawer = function() {
var panel = app.$.paperDrawerPanel;
var responsiveWidth = parseInt(panel.responsiveWidth);
if (window.innerWidth > responsiveWidth) {
if (panel.forceNarrow) {
panel.forceNarrow = false;
panel.togglePanel();
} else {
panel.forceNarrow = true;
panel.togglePanel();
}
}
}
在index.html更改行：
<paper-icon-button id="paperToggle" icon="menu" paper-drawer-toggle></paper-icon-button>
包含on-tap="toggleDrawer"
<paper-icon-button id="paperToggle" icon="menu" on-tap="toggleDrawer" paper-drawer-toggle></paper-icon-button>
如果这不起作用，请发表评论，我会调查问题。
