## Changelog

See the [releases page](https://github.com/arkon/ng-sidebar/releases) on GitHub.


## Usage

Add `SidebarModule` to your app module:

```typescript
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.

```typescript
@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](https://github.com/arkon/ng-sidebar/issues/100) for more info.)

A directive is also provided to easily close the sidebar by clicking something inside it:

```html
<ng-sidebar>
  <a closeSidebar>Closes the sidebar</a>
</ng-sidebar>
```

You can also use the `open()` and `close()` functions:

```html
<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](https://angular.io/guide/component-styles#deep) for more details. Note that the `/deep/` selector [will soon be deprecated](https://groups.google.com/a/chromium.org/forum/#!msg/blink-dev/68qSZM5QMRQ/pT2YCqZSomAJ).
