Getting Started


  • The Mutiselect Dropdown package is published on the npm Registry.
  • Install the package :
`npm install angular2-multiselect-dropdown`
  • Once installed import AngularMultiSelectModule from the installed package into your module as follows:


Import AngularMultiSelectModule into NgModule in app.module.ts. Angular's FormsModule is also required.
import { AngularMultiSelectModule } from 'angular2-multiselect-dropdown';
import { FormsModule } from '@angular/forms';

  // ...
  imports: [
  // ...

Declare the component data variables and options in your component where you want to consume the dropdown component.
import { Component, OnInit } from '@angular/core';

export class AppComponent implements OnInit {
    dropdownList = [];
    selectedItems = [];
    dropdownSettings = {};
        this.dropdownList = [
                              {"id":5,"itemName":"South Korea"},
        this.selectedItems = [
                                {"id":5,"itemName":"South Korea"}
        this.dropdownSettings = { 
                                  singleSelection: false, 
                                  text:"Select Countries",
                                  selectAllText:'Select All',
                                  unSelectAllText:'UnSelect All',
                                  enableSearchFilter: true,
                                  classes:"myclass custom-class"
    onSelectAll(items: any){
