Introduction

Ngx-Bootstrap has released a package of open-source tools which is native Angular directives for Bootstrap 3 and 4. It contains all core components powered by Angular. In this article we will learn about Typehead component which is a cool feature of Ngx-bootstrap.

What is Typeahead?

Typeahead - also known as autocomplete or autosuggest is a language prediction tool that many search interfaces use to provide suggestions for users as they type in a textbox.This is a method for searching and filtering through text. It is also sometimes known as autocomplete, incremental search, search-as-you-type and inline search.

Prerequisites

Basic knowledge of Angular
Visual Studio Code must be installed
Angular CLI must be installed
Node JS must be installed

Step 1

Let's create a new Angular project using the following NPM command,

ng new typehead-example

Step 2

Now, let's create a new component by using the following command,

ng g c ngx-bootstrap-typehead

Step 3

Install ngx-bootstrap from npm by using the folowing command.

npm install ngx-bootstrap --save

ng add ngx-bootstrap --component typeahead

This will be added to our root module

Step 4

Now let's add bootstrap styles in our index.html file .

For Bootstrap 3,

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

For Bootstrap 4

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">

Step 5

Let add the template in our ngx-bootstrap-typehead.component.html.

<h2>Example of Ngx-Bootstrap Typehead</h2>
<div style="width: fit-content;margin: auto;margin-top: 18px;">
<pre style="background-color: antiquewhite;" class="card card-block card-header mb-3">Selected option: {{selectedOption | json}}</pre>
<input [(ngModel)]="selectedValue" [typeahead]="countries" typeaheadOptionField="name" [typeaheadScrollable]="true"
(typeaheadOnSelect)="onSelect($event)" class="form-control">
</div>

Step 6

Now, open the ngx-bootstrap-typehead.component.ts file and add the following code in this file,

import { Component } from '@angular/core';
import { TypeaheadMatch } from 'ngx-bootstrap/typeahead/typeahead-match.class';
@Component({
selector: 'app-ngx-bootstrap-typeahead',
templateUrl: './ngx-bootstrap-typeahead.component.html'
})
export class NgxBootstrapTypeaheadComponent {
selectedValue: string;
selectedOption: any;
countries: any[] = [

onSelect(event: TypeaheadMatch): void {
this.selectedOption = event.item;
}
}

Step 7

Now, open the app.component.html file and add the following code in the file,

<app-ngx-bootstrap-typeahead></app-ngx-bootstrap-typeahead>

Step 8

Let's open app.module.ts file and add the following code in the file,

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { NgxBootstrapTypeaheadComponent } from './ngx-bootstrap-typeahead/ngx-bootstrap-typeahead.component';
import { TypeaheadModule } from 'ngx-bootstrap/typeahead';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
declarations: [
AppComponent,
NgxBootstrapTypeaheadComponent
],
imports: [
BrowserModule,
TypeaheadModule.forRoot(),
BrowserAnimationsModule,
FormsModule,
ReactiveFormsModule,
HttpClientModule
],
bootstrap: [AppComponent]
})
export class AppModule { }
