Use Jquery with Angular
In this article I will explain with an example, how to use Jquery with Angular
For use *ngIf and *ngFor on same element, You need to use <ng-container> or <template>. both of the uses is same.
What is ng-container
<ng-container> if you need a helper element for nested structural directives like *ngIf or *ngFor or if you want to wrap more than one element inside such a structural directive;
When we use ng-container or template
Angular v6 recommend to use <ng-container> instead of <template>
<ng-container *ngFor="let navLink of navLinks"> <li *ngIf="navLink.show"> ..... </li> </ng-container>
Before Angular v6, we use <template> as a placeholder
<template *ngFor="let navLink of navLinks" > <li *ngIf="navLink.show"> ..... </li> </template>
