Conditionally swap elements position in a row
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);
}
}
}

Thanks! I ended up using the css solution but the Angular one was also very helpful!

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.

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>
