How to use select2 in Angular 14?

Hello friends, welcome back to my blog. Today in this blog post, I am going to show you, How to use select2 in Angular 14?

Angular 14 came and if you are new then you must check below link:

1. Angular14 Basic Tutorials

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 14 setup and for this we need to run below commands but if you already have angular 14 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angulardemo //Create new Angular Project

cd angulardemo // Go inside the Angular Project Folder

2. Now friends, here we need to run below commands into our project terminal to install select2 packages:

npm i ng-select2-component --save

ng serve --o

3. Now friends we need to  add below code into your src/app/app.module.ts file:

...
import { Select2Module } from 'ng-select2-component';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
   ...
    Select2Module
  ],
...

4. Now friends we just need to add below code into src/app/app.component.ts file:

import { Component } from '@angular/core';
import { Select2Option, Select2UpdateEvent } from 'ng-select2-component';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angulardemos';
  overlay = false;

  data1:any= [
    {
        label: 'Alaskan/Hawaiian Time Zone',
        options: [
            { value: 'AK', label: 'Alaska' },
            { value: 'HI', label: 'Hawaii', disabled: true },
        ],
    },
    {
        label: 'Pacific Time Zone',
        options: [
            { value: 'CA', label: 'California' },
            { value: 'NV', label: 'Nevada' },
            { value: 'OR', label: 'Oregon' },
            { value: 'WA', label: 'Washington' },
        ],
    },
    {
        label: 'Mountain Time Zone',
        options: [
            { value: 'AZ', label: 'Arizona' },
            { value: 'CO', label: 'Colorado' },
            { value: 'ID', label: 'Idaho' },
            { value: 'MT', label: 'Montana' },
            { value: 'NE', label: 'Nebraska' },
            { value: 'NM', label: 'New Mexico' },
            { value: 'ND', label: 'North Dakota' },
            { value: 'UT', label: 'Utah' },
            { value: 'WY', label: 'Wyoming' },
        ],
    },
    {
        label: 'Central Time Zone',
        options: [
            { value: 'AL', label: 'Alabama' },
            { value: 'AR', label: 'Arkansas' },
            { value: 'IL', label: 'Illinois' },
            { value: 'IA', label: 'Iowa' },
            { value: 'KS', label: 'Kansas' },
            { value: 'KY', label: 'Kentucky' },
            { value: 'LA', label: 'Louisiana' },
            { value: 'MN', label: 'Minnesota' },
            { value: 'MS', label: 'Mississippi' },
            { value: 'MO', label: 'Missouri' },
            { value: 'OK', label: 'Oklahoma' },
            { value: 'SD', label: 'South Dakota' },
            { value: 'TX', label: 'Texas' },
            { value: 'TN', label: 'Tennessee' },
            { value: 'WI', label: 'Wisconsin' },
        ],
    },
    {
        label: 'Eastern Time Zone',
        options: [
            { value: 'CT', label: 'Connecticut' },
            { value: 'DE', label: 'Delaware' },
            { value: 'FL', label: 'Florida' },
            { value: 'GA', label: 'Georgia' },
            { value: 'IN', label: 'Indiana' },
            { value: 'ME', label: 'Maine' },
            { value: 'MD', label: 'Maryland' },
            { value: 'MA', label: 'Massachusetts' },
            { value: 'MI', label: 'Michigan' },
            { value: 'NH', label: 'New Hampshire' },
            { value: 'NJ', label: 'New Jersey' },
            { value: 'NY', label: 'New York' },
            { value: 'NC', label: 'North Carolina' },
            { value: 'OH', label: 'Ohio' },
            { value: 'PA', label: 'Pennsylvania' },
            { value: 'RI', label: 'Rhode Island' },
            { value: 'SC', label: 'South Carolina' },
            { value: 'VT', label: 'Vermont' },
            { value: 'VA', label: 'Virginia' },
            { value: 'WV', label: 'West Virginia' },
        ],
    },
];

change(key: string, event: Event) {
  console.log(key, event);
}

search(text: string) {
  this.data1 = text
      ? (JSON.parse(JSON.stringify(this.data1)) as Select2Option[]).filter(
            option => option.label.toLowerCase().indexOf(text.toLowerCase()) > -1,
        )
      : JSON.parse(JSON.stringify(this.data1));
}
update(key: string, event: Select2UpdateEvent<any>) {
  console.log(event.value);
}
value1 = 'CA';

}

5. Now friends we need to add below code into app.component.html file to get final output on web browser:

<select2
        [overlay]="overlay"
        [data]="data1"
        [value]="value1"
        (update)="update('value1', $event)"
        (change)="change('change1', $event)"
        (search)="search('search1')"
        resettable
        id="selec2-1"
    >
    </select2>

Now we are done friends and please run ng serve command and if you have any kind of query then please do comment below.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding must watch video above.

I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad.
