Sticky toolbar material 2 and sidenav

Solution 1

To keep the toolbar on top, use position: fixed and z-index: 999. To keep the sidenav outside of scrollable area, it needs to be taken outside of md-sidenav-container

Thanks for creating a the plnkr demo, it helped a lot to quickly find a solution. Here's the modified demo.

app.component.html:

<md-toolbar class="fixed-header">
      <button class="app-icon-button" (click)="start.toggle()">
      <i class="material-icons app-toolbar-menu">menu</i>
      </button>
</md-toolbar>

<md-sidenav-container >
    <div class="text" style="min-height: 99vh">
      {{ text }}
    </div>
</md-sidenav-container>

<md-sidenav #start class="app-sidebar side-nav-style" mode="side" >
        test
</md-sidenav>

app.component.css:

.fixed-header {
  top: 0;
  position: fixed;
  z-index:999;

}

.text { 
  width: 5px;
}

.side-nav-style{
  background-color: grey;
  width: 6em;
  margin-top:62px;
  position: fixed
}

Let me know if that's what you are looking for.

Solution 2

@Nehal the example still has an issue where the <md-sidenav-container> is under the top toolbar shown here in an updated plnkr:

If you follow the official Angular docs, see the "Fixed sidenav" example from the link below, you should get the desired look with the sticky toolbar.

Started recently learning material 2 and ran to issue. My approach is to do a sidenav as in Youtube website. There is a hamburger menu on left which expands/collapses side menu. Code:

<md-toolbar class="fixed-header">
     <button class="app-icon-button" (click)="start.toggle()">
          <i class="material-icons app-toolbar-menu">menu</i>
     </button>
</md-toolbar>

<md-sidenav-container>
    <md-sidenav #start class="app-sidebar" mode="side">test</md-sidenav>

    <div class="text">
      {{ text }}
    </div>
</md-sidenav-container>

Now seems like I achieved the layout, but the positioning is not fixed, if i scroll toolbar moves and sidenav content also moves.

Edit:

On angular material documentation I later found the example which one I have been looking for:

https://stackblitz.com/angular/rmjxrpxdgmx?file=app%2Fsidenav-responsive-example.html

if link will be removed, here is the code:

HTML File:

<div class="example-container" [class.example-is-mobile]="mobileQuery.matches" *ngIf="shouldRun">
  <mat-toolbar color="primary" class="example-toolbar">
    <button mat-icon-button (click)="snav.toggle()"><mat-icon>menu</mat-icon></button>
    <h1 class="example-app-name">Responsive App</h1>
  </mat-toolbar>

  <mat-sidenav-container class="example-sidenav-container"
                         [style.marginTop.px]="mobileQuery.matches ? 56 : 0">
    <mat-sidenav #snav [mode]="mobileQuery.matches ? 'over' : 'side'"
                 [fixedInViewport]="mobileQuery.matches" fixedTopGap="56">
      <mat-nav-list>
        <a mat-list-item routerLink="." *ngFor="let nav of fillerNav">{{nav}}</a>
      </mat-nav-list>
    </mat-sidenav>

    <mat-sidenav-content>
      <p *ngFor="let content of fillerContent">{{content}}</p>
    </mat-sidenav-content>
  </mat-sidenav-container>
</div>

TS File:

import {MediaMatcher} from '@angular/cdk/layout';
import {ChangeDetectorRef, Component, OnDestroy} from '@angular/core';

/** @title Responsive sidenav */
@Component({
  selector: 'sidenav-responsive-example',
  templateUrl: 'sidenav-responsive-example.html',
  styleUrls: ['sidenav-responsive-example.css'],
})
export class SidenavResponsiveExample implements OnDestroy {
  mobileQuery: MediaQueryList;

  fillerNav = Array.from({length: 50}, (_, i) => `Nav Item ${i + 1}`);

  fillerContent = Array.from({length: 50}, () =>
      `Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut

  private _mobileQueryListener: () => void;

  constructor(changeDetectorRef: ChangeDetectorRef, media: MediaMatcher) {
    this.mobileQuery = media.matchMedia('(max-width: 600px)');
    this._mobileQueryListener = () => changeDetectorRef.detectChanges();
    this.mobileQuery.addListener(this._mobileQueryListener);
  }

  ngOnDestroy(): void {
    this.mobileQuery.removeListener(this._mobileQueryListener);
  }
}

CSS File:

.example-container {
  display: flex;
  flex-direction: column;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}

.example-is-mobile .example-toolbar {
  position: fixed;
  /* Make sure the toolbar will stay on top of the content as it scrolls past. */
  z-index: 2;
}

h1.example-app-name {
  margin-left: 8px;
}

.example-sidenav-container {
  /* When the sidenav is not fixed, stretch the sidenav container to fill the available space. This
     causes `<mat-sidenav-content>` to act as our scrolling element for desktop layouts. */
  flex: 1;
}

.example-is-mobile .example-sidenav-container {
  /* When the sidenav is fixed, don't constrain the height of the sidenav container. This allows the
     `<body>` to be our scrolling element for mobile layouts. */
  flex: 1 0 auto;
}

Well okay about header, but what about side bar ? I wish it would not hide the content of container, but container would move also to right, and side nav would be fixed, would not scroll as you scroll down content.
