Dependencies:

Creating Angular Project: 

To create the Angular project using the Angular CLI tool, follow the steps.

1. Install the Angular CLI application in your machine.

npm install -g @angular/cli@11.2.3

2. Now create a new Angular 11 project using the command `ng new` and navigate to that folder.

ng new angular11-app

cd angular11-app

3. Install the ej2-angular-dropdowns package through the npm install command.

npm install @syncfusion/ej2-angular-dropdowns –save

Adding Angular 11 MultiSelect Dropdown

You can add the Angular 11 MultiSelect Dropdown component by using the `ej2-multiselect` directive. The attributes used within this tag allow you to define other MultiSelect Dropdown functionalities. To add the Angular 11 MultiSelect Dropdown, follow the steps:

1. Import the MultiSelectAllModule into the app.module.ts file from the ej2-angular-dropdowns package.
2. Import and inject the other required modules within the providers section of app.module.ts.

[app.module.ts]

import { BrowserModule, } from '@angular/platform-browser';

import { MultiSelectAllModule } from '@syncfusion/ej2-angular-dropdowns';

 

import { NgModule } from '@angular/core';

import { FormsModule }   from '@angular/forms';

import { AppComponent } from './app.component';

 

@NgModule({

  declarations: [

    AppComponent

  ],

  imports: [

    BrowserModule, FormsModule, MultiSelectAllModule

  ],

  bootstrap: [AppComponent]

})

export class AppModule { }

3. Define the Angular MultiSelect Dropdown code within the app.component.html file, which is mapped against the templateUrl option in the app.component.ts file.

 [app.component.html] 

<ejs-multiselect></ejs-multiselect>

4. Refer to the CDN link of CSS reference within the index.html file.

[index.html] 

<link href="https://cdn.syncfusion.com/ej2/material.css" rel="stylesheet" />

Loading data

You can populate the empty MultiSelect Dropdown with data by using the JSON data through the `datasource` property.

import { Component } from '@angular/core';

 

@Component({

  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css'],

})

export class AppComponent {

     // define the JSON of data

     public countries: { [key: string]: Object; }[] = [

        { Name: 'Australia', Code: 'AU' },

            { Name: 'Bermuda', Code: 'BM' },

            { Name: 'Canada', Code: 'CA' },

            { Name: 'Cameroon', Code: 'CM' },

            { Name: 'Denmark', Code: 'DK' },

            { Name: 'France', Code: 'FR' },

            { Name: 'Finland', Code: 'FI' },

            { Name: 'Germany', Code: 'DE' },          

        ];

        // maps the local data column to fields property

        public localFields: Object = { text: 'Name', value: 'Code' };

        // set the placeholder to MultiSelect Dropdown input element

        public localWaterMark: string = 'Select countries';

}

[app.component.html]

<ejs-multiselect id='localData' #local [dataSource]='countries' [fields]='localFields' [placeholder]='localWaterMark'></ejs-multiselect>

Setting initial select value on MultiSelect Dropdown: 

You can populate the empty MultiSelect Dropdown with value by binding the string data through the `value` property initially.

[app.component.ts]

import { Component } from '@angular/core';

 

@Component({

  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css'],

})

export class AppComponent {

         public value: string[] = ['AU'];

}

Now, assign this value to the `value` property of Angular MultiSelect Dropdown within the app.component.html file.

[app.component.html]

<ejs-multiselect id='localData' #local [dataSource]='countries' [fields]='localFields' [placeholder]='localWaterMark' [value]='value'

></ejs-multiselect>

Screenshot

Getting the selected value on form submit.

By using the ngModel, you can get the value from the ngform submit.

[app.component.ts]

import { Component } from '@angular/core';

 

@Component({

  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css'],

})

export class AppComponent {

        onSubmit(form: NgForm): void {

            console.log(form.value.name);

          }

}

[app.component.html]

<form #form='ngForm' (ngSubmit)="onSubmit(form)">

    <div class="form-group"> 

        <ejs-multiselect id='localData' name='name'  #local='ngModel' [(value)]='value'[(ngModel)]='value' [dataSource]='countries' [fields]='localFields' [placeholder]='localWaterMark'></ejs-multiselect>

        <button type="submit" ejs-button>Submit</button>

    </div>

  </form>
