角度、材质侧导航和粘性工具栏 [英] Angular, material side nav and sticky toolbar

问题描述

我正在试验材质侧导航和 Angular 6/7.我想要实现的目标显示在接下来的两张图片中.

I'm experimenting with material side nav and Angular 6/7. What I want to achieve is shown on the next two images.

带有折叠侧边导航的应用:

The app with collapsed side nav:

具有扩展侧导航的应用:

The app with expanded side nav:

简而言之:

• 可以通过按钮打开和关闭的侧面导航.
• 内容上方的固定工具栏.
• 可滚动的内容.

基本结构如下，提示这里.

<mat-sidenav-container>
  <mat-sidenav mode="side" opened>Sidenav content</mat-sidenav>
  <mat-sidenav-content>Main content, toolbar here</mat-sidenav-content>
</mat-sidenav-container>

可以在此处的stackblitz找到最小的工作示例.

A minimal working sample can be found here, at stackblitz.

我的问题:当我开始滚动时，工具栏没有粘性并且与内容一起滚动.

My problem: the toolbar is not sticky and scrolls together with the content when I start scrolling.

我的问题:如何让工具栏固定在顶部而不与内容一起滚动?

My question: How can I make the toolbar stick on the top and do not scroll together with the content?

注意:侧边导航本身是固定的，因为它有fixedInViewport="true".

Note: The side nav itself is fixed because it has fixedInViewport="true".
