What is @ng-bootstrap/ng-bootstrap?
@ng-bootstrap/ng-bootstrap provides Angular widgets built from the ground up using Bootstrap 4 CSS. It allows developers to use Bootstrap components natively in Angular applications without the need for jQuery.
What are @ng-bootstrap/ng-bootstrap's main functionalities?
Accordion
The Accordion component allows you to create collapsible panels. The example demonstrates a simple accordion with two panels, one titled 'Simple' and the other 'Advanced'.
<ngb-accordion [closeOthers]="true">
<ngb-panel title="Simple">
<ng-template ngbPanelContent>
This is a simple accordion panel.
</ng-template>
</ngb-panel>
<ngb-panel>
<ng-template ngbPanelTitle>
<span>Advanced</span>
</ng-template>
<ng-template ngbPanelContent>
This is an advanced accordion panel.
</ng-template>
</ngb-panel>
</ngb-accordion>
Modal
The Modal component allows you to create and control modal dialogs. The example demonstrates a button that opens a modal with a title, body, and footer.
import { Component } from '@angular/core';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';
@Component({
selector: 'app-modal',
template: `<button class="btn btn-lg btn-outline-primary" (click)="open(content)">Launch demo modal</button>
<ng-template #content let-modal>
<div class="modal-header">
<h4 class="modal-title">Modal title</h4>
<button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Hello, world!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-outline-dark" (click)="modal.close('Save click')">Save</button>
</div>
</ng-template>`
})
export class ModalComponent {
constructor(private modalService: NgbModal) {}
open(content) {
this.modalService.open(content, { ariaLabelledBy: 'modal-basic-title' }).result.then((result) => {
console.log(`Closed with: ${result}`);
}, (reason) => {
console.log(`Dismissed ${reason}`);
});
}
}
Tooltip
The Tooltip component allows you to add tooltips to elements. The example demonstrates a button with a tooltip that appears on top when hovered.
<button type="button" class="btn btn-outline-secondary" ngbTooltip="Tooltip on top" placement="top">Tooltip on top</button>
Datepicker
The Datepicker component allows you to add a date selection widget. The example demonstrates a simple datepicker bound to a model.
<ngb-datepicker [(ngModel)]="model"></ngb-datepicker>

Installation
We strongly recommend using Angular CLI for setting up a new project. If you have an Angular ≥ 9 CLI project, you could simply use our schematics to add ng-bootstrap library to it.
Just run the following:
ng add @ng-bootstrap/ng-bootstrap
It will install ng-bootstrap for the default application specified in your angular.json
.
If you have multiple projects and you want to target a specific application, you could specify the --project
option:
ng add @ng-bootstrap/ng-bootstrap --project myProject
If you prefer not to use schematics and install everything manually, please refer to the
manual installation instructions on our website.
Supported browsers
We support the same browsers and versions supported by both Bootstrap 4 and Angular, whichever is more restrictive. See Angular browser support and Bootstrap browser support for more details.
Our code is automatically tested on all supported browsers.
Getting help
Please, do not open issues for the general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on StackOverflow where maintainers are looking at questions tagged with ng-bootstrap
.
StackOverflow is a much better place to ask questions since:
- there are hundreds of people willing to help on StackOverflow
- questions and answers stay available for public viewing so your question / answer might help someone else
- SO voting system assures that the best answers are prominently visible.
To save your and our time we will be systematically closing all the issues that are requests for general support and redirecting people to StackOverflow.
You think you've found a bug?
We want to fix it ASAP! But before fixing a bug we need to reproduce and confirm it.
We ask you to respect two things:
- fill the GitHub issue template by providing the bug description and appropriate versions of Angular, ng-bootstrap and TypeScript
- provide a use-case that fails with a minimal reproduction scenario using StackBlitz (you can start by forking one from our demo page)
A minimal reproduction scenario allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
Please note that we will be insisting on a minimal reproduce scenario in order to save maintainers time and ultimately be able to fix more bugs. We'll mark the issue as non-actionable without it and close if not heard from the reporter.
Interestingly, from our experience users often find coding problems themselves while preparing a minimal StackBlitz. We understand that sometimes it might be hard to extract essentials bits of code from a larger code-base but we really need to isolate the problem before we can fix it.
