Multiselect

This project focuses on serving an intuitive select control. This look and feel of the component has been inspired by AngularJS isteven-multiselect directive, but from coding perspective, this may not be architectured in the similar way. It supports ultimate features like

• 🖱️Virtual scroll
• 📃Forms
• 🎨Theming (bootstrap/material)
• 👀Observable
• 🅰️@angular 6+
• 👨‍👧‍👧Grouping
• etc...

Getting Started

It's super easy to get started with Angular multiselect dropdown. Only three steps are required:

1. Install @ngx-lib/multiselect package

2. Import module NgxMultiselectModule into your app.module.ts

   import { NgxMultiselectModule } from '@ngx-lib/multiselect';
   
   @NgModule({
       imports: [
           ...,
           NgxMultiselectModule // <-- add module in imports
       ],
       bootstrap: [AppComponent],
       providers: [...],
       declarations: [...]
   })
   export class AppModule {
   
   }

3. Use ngx-multiselect on HTML

   <ngx-multiselect [(ngModel)]="selectedCountry" [options]="countries" ngDefaultControl> </ngx-multiselect>

   import { Component, OnInit } from '@angular/core';
   
   @Component({...})
   export class AppComponent implements OnInit {
       countries;
       selectedCountry;
   
       ngOnInit() {
           this.countries = [
               { id: 1, name: "India"},
               { id: 2, name: "USA" },
               { id: 3, name: "China" },
               { id: 4, name: "Japan" }
           ];
   
           this.selectedCountry = [{
               id: 1,
               name: "India"
           }];
       }
   }

Developer tasks

We use npm to manage the dependencies and to run build tasks. You should run all these tasks from the multiselect/docs_app folder. Here are the most important tasks you might need to use:

• npm install - install all the dependencies.

• npm run setup - install all the dependencies and run dgeni on the docs.

• npm run build - create a production build of the application (after installing dependencies, etc).

• npm start - run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary.

• npm run serve-and-sync - run both the docs-watch and start in the same console.

• npm run lint - check that the doc-viewer code follows our style rules.

• npm test - watch all the source files, for the doc-viewer, and run all the unit tests when any change.

• npm test -- --watch=false - run all the unit tests once.

• npm run e2e - run all the e2e tests for the doc-viewer.

• npm run docs - generate all the docs from the source files.

• npm run docs-watch - watch the multiselect source and the docs files and run a short-circuited doc-gen for the docs that changed (don't work properly at the moment).

• npm run docs-lint - check that the doc gen code follows our style rules.

• npm run docs-test - run the unit tests for the doc generation code.

• npm run build-ie-polyfills - generates a js file of polyfills that can be loaded in Internet Explorer.
