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.
