Usage
Add SidebarModule to your app module:
import { SidebarModule } from 'ng-sidebar';
@NgModule({
declarations: [AppComponent],
imports: [BrowserModule, SidebarModule.forRoot()],
bootstrap: [AppComponent],
})
class AppModule {}
In your app component, simply use add a <ng-sidebar-container> wrapper, then place your <ng-sidebar>(s) and content within it. Your page content should be in some container with a ng-sidebar-content attribute.
@Component({
selector: 'app',
template: `
<!-- Container for sidebar(s) + page content -->
<ng-sidebar-container>
<!-- A sidebar -->
<ng-sidebar [(opened)]="_opened">
<p>Sidebar contents</p>
</ng-sidebar>
<!-- Page content -->
<div ng-sidebar-content>
<button (click)="_toggleSidebar()">Toggle sidebar</button>
</div>
</ng-sidebar-container>
`
})
class AppComponent {
private _opened: boolean = false;
private _toggleSidebar() {
this._opened = !this._opened;
}
}
If nothing seems to show up, your wrappers' heights may be collapsing. Try adding a height (e.g. height: 100vh;) to the wrapper <ng-sidebar-container> or other wrapper elements you may have. (See issue #100 for more info.)
A directive is also provided to easily close the sidebar by clicking something inside it:
<ng-sidebar>
<a closeSidebar>Closes the sidebar</a>
</ng-sidebar>
You can also use the open() and close() functions:
<ng-sidebar #sidebar>
<button (click)="sidebar.close()">Close sidebar</button>
</ng-sidebar>
<button (click)="sidebar.open()">Open sidebar</button>
Functions
The sidebar has a few public functions:
| Function | Description |
|---|---|
open() |
Opens the sidebar. |
close() |
Closes the sidebar. |
triggerRerender() |
Manually trigger a re-render of the container. Useful if the sidebar contents might change. |
Styling
Various class names are attached to the sidebar and container for easier styling.
If you are using Angular's default emulated view encapsulation, you may have to use the >>> selector to target the sidebar's classes. Check out Angular's documentation for more details. Note that the /deep/ selector will soon be deprecated.
