Alerts

The Alerts component allows you to display different types of alert messages such as success, info, warning, and danger. This is useful for providing feedback to users.

<input type="text" class="form-control" bsDatepicker>

Tabs

The Tabs component allows you to create tabbed interfaces. This is useful for organizing content into separate sections that can be easily navigated by users.

<tabset>
  <tab heading="Tab 1">Content of Tab 1</tab>
  <tab heading="Tab 2">Content of Tab 2</tab>
</tabset>

Tooltips

The Tooltips component provides a way to display additional information when users hover over or focus on an element. This is useful for providing contextual help or explanations.

Installation

Angular CLI way

Use the Angular CLI ng add command for updating your Angular project.

ng add ngx-bootstrap

Manual way

Install ngx-bootstrap from npm:

npm install ngx-bootstrap --save

Add wanted package to NgModule imports:

import { TooltipModule } from 'ngx-bootstrap/tooltip';

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

Add component to your page:

<button type="button" class="btn btn-primary"
        tooltip="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Simple demo
</button>

You will need to add bootstrap css:

• Bootstrap 3

<!-- index.html -->
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

• Bootstrap 4

<!--- index.html -->
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.3/css/bootstrap.min.css" rel="stylesheet">

Setting up the bootstrap version manually

As you may know ngx-bootstrap support several bootstrap.css versions at the same time and has automatic tool to guess current used version of library, but if this guess fails you can specify version of bootstrap.css manually.

Sometimes, your project might contain some library that could interfere with the bootstrap framework, or you might have a customized version of bootstrap. The consequence is that the process of determining bootstrap version might be failed, which can break the UI. In that case, we can still set the bootstrap version manually in the bootstrapping component (i.e. AppComponent):

import { setTheme } from 'ngx-bootstrap/utils';

@Component({...})
export class AppComponent {
  constructor() {
    setTheme('bs3'); // or 'bs4'
    ...
  }
}

How to build lib for development

First time:

git clone https://github.com/valor-software/ngx-bootstrap.git
cd ngx-bootstrap
npm ci
npm run build
npm start

Troubleshooting

So if you are in trouble, here's where you can look for help.

The best place to ask questions is on StackOverflow (under the ngx-bootstrap tag) You can also join our Slack channel and link your stackoverflow question there. But try to avoid asking generic help questions directly on Slack since they can easily get lost in the chat. You can also search among the existing GitHub issues.

If, and only if, none of the above helped, please open a new issue.
