Instalation

1. Install NgSelector

1. Include dependencies into angular.cli

"styles": [
  "../node_modules/selectize/dist/css/selectize.bootstrap3.css",
  "styles.css"
],
"scripts": [
  "../node_modules/jquery/dist/jquery.min.js",
  "../node_modules/selectize/dist/js/standalone/selectize.js"
],

1. Add NgSelectorModule as dependency

import { NgModule } from '@angular/core';
import { NgSelectorModule } from 'ng-selector';
 
import { AppComponent } from './app.component';
 
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    ...,
    NgSelectorModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

API

    <ng-selector
      [(ngModel)]="selectedObject"
      [options]="arrayOfObjects"
      [readonly]="disabled"
      [plugins]="['remove_button']"
      (loadValues)="fetchDataFromServer($event.query, $event.result)"
      (renderer)="render($event.item, $event.html)"
      placeholder="A placeholder..."
      id-field="uid" // customize id field name - 'id' by default
      label-field="name" // customize label field name - 'label' by default
      multiple="true" // allow multiple selection
      allow-creation="true" // allow user to manually enter a new value
      >
    </ng-selector>

Usage

Main usage is to let user select an object into an array of object. It is possible to do async data loading and custom rendering.

Simple selection

export class AppComponent {
  selected: any;
 
  values = [
    { id: 1, label: 'First value' },
    { id: 2, label: 'Second value' },
    { id: 3, label: 'Another one' },
    { id: 42, label: 'Best value' },
  ];
}

  <ng-selector name="selector" [(ngModel)]="selected" [options]="values"></ng-selector>

Custom object

export class AppComponent {
  values = [
    { uid: 1, nameOfObject: 'First value' },
    { uid: 2, nameOfObject: 'Second value' },
    { uid: 3, nameOfObject: 'Another one' },
    { uid: 42, nameOfObject: 'Best value' },
  ];
 
  selected = this.values[0];
}

  <ng-selector name="selector" [(ngModel)]="selected" [options]="values" id-field="uid" label-field="nameOfObject"></ng-selector>

Multiple selection

  <ng-selector name="selector" [(ngModel)]="selected" [options]="values"
      multiple="true" placeholder="Choose any values you want...">
  </ng-selector>

Integration with NgForm

export class AppComponent {
  values = [
    { id: 1, name: 'First value' }, { id: 2, name: 'Second value' },
    { id: 3, name: 'Another one' }, { id: 42, name: 'Best value' },
  ];
 
  selected = this.values[0];
 
  get disabled() {
    return this.formConfirmed;
  }
}

  <ng-selector name="selector" [(ngModel)]="selected" [options]="values" [readonly]="disabled" required>
  </ng-selector>

Async data loading

export class AppComponent {
  selected: any;
 
  constructor(private http: Http) {}
 
  fetchServer(event) {
     this.http.get(`${url}?search=${event.query}`)
        .subscribe(response => event.result(response.json()));
  }
}

  <ng-selector name="selector" [(ngModel)]="selected" (loadValues)="fetchServer($event)"></ng-selector>

Custom rendering

/!\ rendering function has to be sync

export class AppComponent {
  selected: any;
 
  customRendering(renderer) {
    const item = renderer.val;
    renderer.html(`<small>${item.id} - ${item.label}</small>`);
  }
}

  <ng-selector name="selector" [(ngModel)]="selected" (renderer)="customRendering($event)"></ng-selector>
