Overview for toolbar
<mat-toolbar>
is a container for headers, titles, or actions.
Single row
In the simplest case, a toolbar may be placed at the top of your application and have a single row that includes the title of your application.
Multiple rows
The Material Design spec used to describe toolbars with multiple rows. This can
be done by placing <mat-toolbar-row>
elements inside a <mat-toolbar>
.
<mat-toolbar-row>
<span>Custom Toolbar</span>
</mat-toolbar-row>
Note: Placing content outside a <mat-toolbar-row>
when multiple rows are specified is not
supported.
Positioning toolbar content
The toolbar does not perform any positioning of its content. This gives the user full power to position the content as it suits their application.
A common pattern is to position a title on the left with some actions on the right. This can be
easily accomplished with display: flex
:
<mat-toolbar-row>
<span>Second Line</span>
<span class="example-spacer"></span>
<mat-icon class="example-icon" aria-hidden="false" aria-label="Example user verified icon">verified_user</mat-icon>
</mat-toolbar-row>
.example-spacer {
flex: 1 1 auto;
}
Accessibility
By default, the toolbar assumes that it will be used in a purely decorative fashion and thus sets
no roles, ARIA attributes, or keyboard shortcuts. This is equivalent to having a sequence of <div>
elements on the page.
Generally, the toolbar is used as a header where role="heading"
would be appropriate.
Only if the use-case of the toolbar match that of role="toolbar", the user should add the role and
an appropriate label via aria-label
or aria-labelledby
.
