Angular 2 : ng bootstrap drop down not working for me

I have been trying to implement ng-bootstrap drop down using plunker http://plnkr.co/edit/?p=preview .

Its not working, I am unable to find an issue

在此输入图像描述 .

Below system.config.js code,

 /** * System configuration for Angular samples * Adjust as necessary for your application needs. */ (function (global) { System.config({ paths: { // paths serve as alias 'npm:': 'node_modules/' }, // map tells the System loader where to look for things map: { // our app is within the app folder app: 'app', // angular bundles '@angular/core': 'npm:@angular/core/bundles/core.umd.js', '@angular/common': 'npm:@angular/common/bundles/common.umd.js', '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js', '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js', '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js', '@angular/http': 'npm:@angular/http/bundles/http.umd.js', '@angular/router': 'npm:@angular/router/bundles/router.umd.js', '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js', '@ng-bootstrap/ng-bootstrap': 'node_modules/@ng-bootstrap/ng-bootstrap/bundles/ng-bootstrap.js', // other libraries 'rxjs': 'npm:rxjs', 'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js' }, // packages tells the System loader how to load when no filename and/or no extension packages: { app: { main: './main.js', defaultExtension: 'js' }, rxjs: { defaultExtension: 'js' }, } }); })(this); 

app.module.ts

 import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { NgbdDropdownConfig } from 'app/dropdown-config'; import { AppComponent } from './app.component'; @NgModule({ imports: [ BrowserModule, ], declarations: [ AppComponent,NgbdDropdownConfig ], bootstrap: [ AppComponent ] }) export class AppModule { } 

app.component.ts code

 import { Component } from '@angular/core'; import { NgbModule } from '@ng-bootstrap/ng-bootstrap'; import { NgbdDropdownConfig } from 'app/dropdown-config'; @Component({ selector: 'my-app', template: ` <div class="container-fluid"> <ngbd-dropdown-config></ngbd-dropdown-config> </div>`, }) export class AppComponent { } 

dropdown-config.ts code

 import {Component} from '@angular/core'; import {NgbDropdownConfig} from '@ng-bootstrap/ng-bootstrap'; @Component({ selector: 'ngbd-dropdown-config', templateUrl: 'app/dropdown-config.html', providers: [NgbDropdownConfig] // add NgbDropdownConfig to the component providers }) export class NgbdDropdownConfig { constructor(config: NgbDropdownConfig) { // customize default values of dropdowns used by this component tree config.up = true; config.autoClose = false; } } 

dropdown-config.html

 <p>This dropdown uses customized default values.</p> <div ngbDropdown> <button class="btn btn-outline-primary" id="dropdownMenu3" ngbDropdownToggle>Toggle</button> <div class="dropdown-menu" aria-labelledby="dropdownMenu3"> <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> 

Since there is no error message , I am unable to find issue. Can any one find out what is the issue could be . Thanks.

With the latest version(1.0.0-alpha.18) it is not working with me either. Downgrade to the previous version:

npm i @ng-bootstrap/ng-bootstrap@1.0.0-alpha.17 --save

and should be fine.

@Manjula D Just make below changes in dropdown-config.html

<div ngbDropdown>
  <button class="btn btn-outline-primary" id="dropdownMenu3" ngbDropdownToggle>Toggle</button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenu3" 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.

I had a similar problem:

I ran

npm install --save @ng-bootstrap/ng-bootstrap

npm install --save bootstrap@4.0.0-beta.2

template/html is provided here: https://ng-bootstrap.github.io/#/components/dropdown/examples

In styles.css:

@import "~bootstrap/dist/css/bootstrap.css";

Still things didn't work by this point so I re-ran

npm install

and things worked.
