NG2-group-multiselect

ng2-group-multiselect is an Angular 2 component that allows the selection of multiple items from a select style dropdown box.

It allows the entered values to be organized by groups to allow for easier sorting, and selection of all items in a group.

Demo

Installation:

npm install ng2-group-multiselect

Use Example

Declare in module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { DemoAppComponent } from './app.component';
import { MultiSelectComponent } from "../../src/";

@NgModule({
  declarations: [
    DemoAppComponent,
    MultiSelectComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule
  ],
  providers: [],
  bootstrap: [DemoAppComponent]
})
export class AppModule { }

Component usage

import{Component} from '@angular2/core';

@Component({
    template: `
    <div>
        <hyper-multiselect [inbound]="myDataSet" 
        (outbound)="mySelectedValues"
        [displayKey]="'keyName'"></hyper-multiselect>
    </div> `
})

class App {}

Configuration & Options

This section will list out the available attributes to configure the multi-select component

Inbound - Required

This is the data that you're passing into the component to list out. This should be an array of objects. There are no required fields in this data, unless you want some options selected by default. If that's the case then the object must have a hyperMSSelected: true property.

Example

In your template:

<hyper-multiselect [inbound]="demo1"...></hyper-multiselect>

In your class:

this.demo1 = [{id: 1, dispVal: 'Blue Jays'}, 
    {id: 2, dispVal: 'Maple Leafs'}, 
    {id: 3, dispVal: 'Raptors'}, 
    {id: 4, dispVal: 'Argos'}
];

this.demo1 = [{id: 1, dispVal: 'Blue Jays'}, 
    {id: 2, dispVal: 'Maple Leafs', selected: true}, 
    {id: 3, dispVal: 'Raptors'}, 
    {id: 4, dispVal: 'Argos', hyperMSSelected:true}
];

Outbound - Required

This is the callback that the component will trigger when the selected data has been updated. This is an eventEmitter that will call the callback with ONLY the selected items that the component knows about. Example

In your template:

<hyper-multiselect (outbound)="refreshDemo1Values($event)"...></hyper-multiselect>

In your class:

public refreshDemo1Values(value: any): void {
    this.demo1Vals = value;
}

Display Name - Required

This is the property of your objects that you want to use to display in the selected values list, as well as in the list of available options. The value can be whatever you want, as long as it's a key value in your objects - this should be a string.

Example

In your template:

<hyper-multiselect [displayKey]="'dispVal"...></hyper-multiselect>

In your class:

this.demo1 = [{id: 1, dispVal: 'Blue Jays'}, 
    {id: 2, dispVal: 'Maple Leafs'}, 
    {id: 3, dispVal: 'Raptors'}, 
    {id: 4, dispVal: 'Argos'}
];

Group By - optional

Default - none

This is the property that you'd like to group your items by.

** If you use group by, EVERY object in your array must have a property with that name.

Example

In your template:

<hyper-multiselect [groupBy]="'type'"...></hyper-multiselect>

In your class:

this.demo2 = [{ id: 1, name: "Rose Tyler", type: "companion" }, 
    { id: 2, name: "Donna Noble", type: "companion" }, 
    { id: 3, name: "Martha Jones", type: "companion" }, 
    { id: 4, name: "Dalek", type: "enemy" }
];

All Selected - optional

Default - false

This is a boolean option that, if set to true, will automatically set all of your items passed in to be selected on initialization.

Example

In your template:

<hyper-multiselect [allSelected]="true"...></hyper-multiselect>
