SOLUTION 1

Bootstrap dropdown requires these 3 dependencies:

  • jQuery
  • popper.js
  • Bootstrap

Step 1: Install these 3 dependencies into your Angular App with these commands:

npm install jquery
npm install popper.js
npm install bootstrap

Step 2: Add these .js files into angular.json scripts section so that these 3 .js files will be rendered into HTML.

angular.json

"scripts": [
  "node_modules/jquery/dist/jquery.min.js",
  "node_modules/popper.js/dist/umd/popper.js",
  "node_modules/bootstrap/dist/js/bootstrap.js"
]

SOLUTION 2

Angular Bootstrap Dropdown is also suggested to fix the issue.

Step 1: Install Angular Bootstrap (NG Bootstrap).

npm install @ng-bootstrap/ng-bootstrap

Step 2: Add NgbModule into app.module.ts imports section.

import { NgbModule } from '@ng-bootstrap/ng-bootstrap';

@NgModule({
  imports: [.., NgbModule],
  ..
})

Step 3: Apply Angular Bootstrap Dropdown directive to dropdown.

<div ngbDropdown class="nav-item">
  <a ngbDropdownToggle id="dropdownMenuButton" class="nav-link" aria-haspopup="true" aria-expanded="false"> 
    <img [src]="user.displayAvatarURL"> {{ user.username }}
  </a>
  <div ngbDropdownMenu aria-labelledby="dropdownMenuButton">
    <a ngbDropdownItem routerLink="/dashboard">Dashboard</a>
      <hr class="m-1">
    <a ngbDropdownItem routerLink="/logout">Logout</a>
  </div>
</div>
