Conditionally swap elements position in a row












1















I have a component that displays a row in a grid-system simil-bootstrap. It is as simple as an image on the left and some body text on the right, both pulled dynamically from a CMS.



I am trying to add a condition that would display the text first and then the image, or vice versa.
ng-container and ng-template seems like the way to go, but I can't figure out how.



I am looking for something like:



<ng-container *ngIf="content.switched; then Image and Text; else Text and Image"></ng-container>

<ng-template #Image> ... </ng-template>
<ng-template #Text> ... </ng-template>


Thanks!

          I guess the best way to do this is by using CSS Flexboxes (row vs row-reverse). If you cannot use Flexbox, or just want to to this using Angular, a suitable approach could be using the directive's or component's ViewContainerRef to add the templates in the desired order:



          @Component({
          ...
          })
          public class AnyComponent implements OnInit {
          @ViewChild('Image')
          public imageTemplate: TemplateRef<any;>
          @ViewChild('Text') // grabs a reference to the <ng-template #Text>
          public textTemplate: TemplateRef<any;>

          constructor(private viewContainer: ViewContainerRef) {}

          public ngOnInit(): void {
          if(condition) {
          this.viewContainer.createEmbeddedView(this.textTemplate);
          this.viewContainer.createEmbeddedView(this.imageTemplate);
          } else {
          this.viewContainer.createEmbeddedView(this.imageTemplate);
          this.viewContainer.createEmbeddedView(this.textTemplate);
          }

          }
          }

          It can be done with two ng-container elements, each one displaying a template with the ngTemplateOutlet directive and selecting the template with a conditional expression:



          <ng-container *ngTemplateOutlet="content.switched ? Image : Text"></ng-container>
          <ng-container *ngTemplateOutlet="content.switched ? Text : Image"></ng-container>

          <ng-template #Image>...</ng-template>
          <ng-template #Text>...</ng-template>


          See this stackblitz for a demo.
