The component is used to create a menu in Angular applications following the Material Design guidelines. It typically consists of a trigger element (e.g., a button) and a hidden menu that appears when the trigger is interacted with (e.g., clicked).
Before writing code in our HTML components, we initially imported and declared the MatMenuModule in "groups.module.ts".
import {MatMenuModule} from '@angular/material/menu';
@NgModule({
declarations: [
// code here
],
imports: [
MatMenuModule
],
exports: [
]
})
Here's a breakdown of the mat-menu component:
Trigger Element: The trigger element is the UI element that, when interacted with, opens the associated menu. It can be any clickable element like a button or an icon. In the example from before, the trigger element is a button with the [matMenuTriggerFor] directive pointing to the mat-menu.
Menu Content: The content of the menu is defined within the <mat-menu> tags. You can include various items inside the menu, such as mat-menu-item for clickable items within the menu.
Configuration: You can configure the menu by using various options. For example, you can use [xPosition] and [yPosition] to control the position of the menu, and [hasBackdrop] to specify whether clicking outside the menu should close it.
<mat-menu #menu="matMenu" [xPosition]="'before'" [yPosition]="'below'" [hasBackdrop]="false">
<!-- menu items go here -->
</mat-menu>
The anticipated output is as follows:
Menu with custom styles
To apply custom styles, we create an HTML class named "custom-menu" and by utilizing this class, we override the existing styles.
<mat-menu #menu="matMenu" class="custom-menu">
<!-- menu items go here -->
</mat-menu>
