Locking mat-toolbar and mat-tabs to the top in Angular Material 2

Question

Locking mat-toolbar and mat-tabs to the top in Angular Material 2

As I work on my website, my goal is to fix the < Mat-Toolbar > at the top of the screen and then directly underneath that, lock the < Mat-Tabs >.

The challenge I'm facing is that the position: fixed in CSS is not working as expected. When I inspect the element on the site, it seems to be adding a < div > unnecessarily.

How can I properly fix these two elements at the top? How do I avoid this automatically generated div? In a previous version of Angular/Angular Material, I was able to solve a similar issue using Fixed and Absolute positioning, but it doesn't seem to apply to this newer version.

Answer №1

Are you looking to create a sticky toolbar? You can achieve this by adding a specific class to the toolbar and setting its position to sticky:

.app-toolbar {
    position: sticky;
    position: -webkit-sticky; /* Support for macOS/iOS Safari */
    top: 0; /* Keeps the toolbar fixed at the top of the page */
    z-index: 1000; /* Prevents content from overlapping with the toolbar */
}

Please note: Internet Explorer 11 does not support position: sticky. To check browser compatibility for position: sticky, you can refer to this Can I Use page.

To achieve this, you can use the following styling approach utilizing ::ng-deep:

::ng-deep .mat-toolbar{
  z-index: 998;
  position: fixed
}
::ng-deep .mat-tab-group{
  margin-top:55px !important;
}

::ng-deep .mat-tab-header{
      z-index: 999;
      width:100vw;
      position: fixed  !important;
      background-color: red !important;
}
::ng-deep .mat-tab-body-wrapper{
    position: relative !important;
    margin-top:55px;
}

While working on my project, I encountered the same issue. It can be quite challenging to keep the toolbar fixed when it's nested within <mat-sidenav-container>.

The difficulty arises because both <mat-sidenav-container> and <mat-toolbar> apply transform: translate3d(0,0,0).

To tackle this problem effectively, the recommended approach is to remove <mat-toolbar> from <mat-sidenav-container> and create an external CSS file for styling the toolbar.

mat-toolbar {
    height: 64px;
    position: fixed;
    z-index: 100;
    width: 100%  !important;
}

Implementing this solution yielded positive results for me.

Finally, here is the answer everyone has been waiting for.

1) Start by navigating to the toolbar component and insert this snippet into its css/scss file :

:host {
  // position: sticky;
  // position: -webkit-sticky; /* For macOS/iOS Safari */
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  z-index: 100;
}

2) Next, proceed to your root app which includes both the top bar and the router-outlet (typically named app.component), and enter the following code in its css/scss file :

:host {
    position: absolute;
    top: 64px;  // specify the height of your topbar here
    bottom: 0;
    left: 0;
    right: 0;
}

It took me a few hours of work, but I am pleased to say that I have found the solution at last.
