what do you mean with multiple link preview container ?

The mat-link-preview-container component ?

Did you try the multiple input ? It will allow you to render multiple links and url within one container..

Hi @AnthonyNahas
Thank is not what I meant. Let's say we have two input fields for links (i.e. one for media articles, one for youtube videos/interviews)

  <form [formGroup]="pressForm">
       <mat-form-field appearance="outline">
              <mat-label> New Article Links </mat-label>
              <textarea matInput matTextareaAutosize matLinkPreview minRows="6" 
                     formControlName="articles"></textarea>	 
        </mat-form-field>
        <mat-link-preview-container [multiple]="true"></mat-link-preview-container> 
    </form>

    <form [formGroup]="videoForm">
            <mat-form-field appearance="outline">
	 	   <mat-label> Video Links </mat-label>
	            <textarea matInput matTextareaAutosize matLinkPreview minRows="6" 
                                    formControlName="videos"></textarea>	
              </mat-form-field>
               <mat-link-preview-container [multiple]="true"></mat-link-preview-container>
    </form>

Now if we put a link inside the first text area, it renders the preview in both containers

Ideally, it would be nice to be able to link input fields to specific containers so multiple instances can be used in the same component. Similar to how Angular Datepicker is implemented

I see! I will really appreciate a PR from you !!

Sorry I had no time to look into this. Have a quite lengthy backlog on my hands and this is towards the bottom. I am not a front end dev so I need to educate myself in type script a little bit before doing this. If anybody wants to pick it up feel free.

From what I remember during my initial pass, this behavior is coming from the fact that the injected service is a singleton. An easy, obvious work around is to, instead of having a shared service, to init one per component but I think it is bad practice to do so.

I think the best way to do this will be to pass the service some sort of identifier and keep the links in a map instead of a list. Datepicker, I believe achieves this through ViewChilds but as I said, I need to dig into datepicker to see exactly how they do it and the 30 files in the repo doesn't make it much easier. I need to block a good chunk of time to dig into that. Will try to get to this Q1 2020 hopefully.
