How to create a dynamic html template with template literals and *ngFor in Angular

like below fixes the issue I have been working on a toast component which will accept html tags as string. Hence I need to loop through below errorMsgs array and build a list dynamically, but the problem is I have a *ngFor inside that and it's looping the array, but I'm not able to print "msg" in the template. , Finally I solved it using ES6 only.
code :
const errorMsgs = ['Not Found', 'Server Error'];

private getMessagesAsHtml(errorMsgs: string[]){
     return `
              ${errorMsgs.map(msg => `
                  <li> ${msg} </li>

Accessing local variable in HTML template using *ngFor in Angular 2

To fix the issue you can do I am trying to use ngFor in Angular 2, sample code below , *ngFor and *ngIf on the same tag is not supported.
Use instead:
code :
  <ng-container *ngFor="let facet of facet_data">
    <a class="collection-item" (click)="setToSearchBarWithFilter(facet.category)" *ngIf="facet.count > 0">
    {{facet.category}}<span class="badge">{{facet.count}}</span> 
  <template ngFor let-facet [ngForOf]="facet_data">
    <a class="collection-item" (click)="setToSearchBarWithFilter(facet.category)" *ngIf="facet.count > 0">
    {{facet.category}}<span class="badge">{{facet.count}}</span> 

Angular 6: Making events equally dynamic on *ngFor-dynamically-generated-template-elements

it should still fix some issue Normally in Angular to show and hide things I create a variable in the component, create a mouseover-mouseout event on the element that toggles that variable, and place an ngIf on any element that I want effected by that event (display/hide). , Try something like this
create empty array
code :

<tr *ngFor="let object of this.data.arrayOfObjects; let i = index">
    <td (mouseenter)="tooltipHover[i]=!tooltipHover[i]" (mouseleave)="tooltipHover[i]=!tooltipHover[i]" class="id-pointer">
        <div *ngIf="this.tooltipHover[i]" class="tooltip">

To fix this issue Check out StackBlitz demo that I created for you. It's leverage the render function cellFn in which you can customize template as you please. Also notice the usage of safeHtml pipe to render html inside template.
EDIT: As the OP stated in comments, he also wants to use Angular directives etc. in template. So here is the StackBlitz demo for this purpose.

Dynamic template reference variable inside ngFor (Angular 2)

By : Infotech

I wish this helpful for you Template reference variables are scoped to the template they are defined in. A structural directive creates a nested template and, therefore, introduces a separate scope.
So you can just use one variable for your template reference
