ng-bootstrap ngbDropdown not working Angular 4

Question

ng dropdowns are not working.

Note: I followed the answer here and upgraded bootstrap to 4-alpha, yet it's not working.

Below is my package.json file:

    "@angular/animations": "^4.3.0",
    "@angular/common": "^4.3.0",
    "@angular/compiler": "^4.3.0",
    "@angular/core": "^4.3.0",
    "@angular/forms": "^4.3.0",
    "@angular/http": "^4.3.0",
    "@angular/platform-browser": "^4.3.0",
    "@angular/platform-browser-dynamic": "^4.3.0",
    "@angular/router": "^4.3.0",
    "@angular/upgrade": "^4.3.0",
    "@ng-bootstrap/ng-bootstrap": "^1.0.0-alpha.28",
    "@types/jquery": "^3.2.8",
    "angular-calendar": "^0.19.0",
    "angular2-ladda": "^1.2.1",
    "angular2-text-mask": "^8.0.2",
    "angular2-toaster": "^4.0.1",
    "animate.css": "^3.5.2",
    "bootstrap": "4.0.0-alpha.6"

html code:

<div ngbDropdown class="d-inline-block">
                <button class="btn btn-outline-primary nav-link dropdown-toggle" id="dropdownBasic1" ngbDropdownToggle>More Actions..</button>
                <div class="dropdown-menu dropdown-menu-right" aria-labelledby="dropdownBasic1">
                    <button class="dropdown-item">Action - 1</button>
                    <button class="dropdown-item">Another Action</button>
                    <button class="dropdown-item">Something else is here</button>
                </div>
            </div>

In my app.module.ts ngbModule is imported too.

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

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    ReactiveFormsModule,
    NgbModule.forRoot()
//more
]

Bootstrap buttons and text inputs working and all the styles are applied, except for dropdown isn't working on click.

Any input is much appreciated.

Solution 1

NgbModule has to be imported within the separate module as well. Credits: HaveSpacesuit

Solution 2

add ngb modules you use, NgbModule has to be imported....

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

@Maddy Just make some minor change to your html code:

<div ngbDropdown class="d-inline-block">
                <button class="btn btn-outline-primary nav-link dropdown-toggle" id="dropdownBasic1" ngbDropdownToggle>More Actions..</button>
                <div class="dropdown-menu dropdown-menu-right" aria-labelledby="dropdownBasic1" ngbDropdownMenu >
                    <button class="dropdown-item">Action - 1</button>
                    <button class="dropdown-item">Another Action</button>
                    <button class="dropdown-item">Something else is here</button>
                </div>
            </div>

ngbDropdownMenu is property added to "dropdown-menu" div.
