Angular Sortable - Setup
Smart UI for Angular supports both standalone components (bootstrapApplication) and NgModule-based apps (bootstrapModule(AppModule)). Steps 1-5 show the standalone path; the section below shows the NgModule path with the same package and styles.
Demo source (Smart UI repo): angular/src/sortable/overview
1 NPM Install
Install the smart-webcomponents-angular package:
npm install smart-webcomponents-angular
2 Register styles
Add the default Smart UI stylesheet to angular.json -> projects -> <your-project> -> architect -> build -> options -> styles (merge with existing entries):
"styles": [ "node_modules/smart-webcomponents-angular/source/styles/smart.default.css" ]
Add optional theme CSS from the same package after smart.default.css if you use Bootstrap, Fluent, or other bundled themes.
3 Import the Angular module
Import SortableModule from smart-webcomponents-angular/sortable: use @Component.imports for standalone, or add it to your AppModule (or feature module) imports array for NgModule apps.
import { SortableModule } from 'smart-webcomponents-angular/sortable';
4 Root component (standalone)
Add SortableModule to your root standalone component (src/app/app.ts). Snippet from Smart UI demos (paths normalized to app.html / App where applicable):
import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
import { CheckBoxComponent } from 'smart-webcomponents-angular/checkbox';
import { SortableComponent } from 'smart-webcomponents-angular/sortable';
import { CheckBoxModule } from 'smart-webcomponents-angular/checkbox';import { SortableModule } from 'smart-webcomponents-angular/sortable';
@Component({
selector: 'app-root',
standalone: true,
imports: [ CheckBoxModule, SortableModule ],
templateUrl: './app.html',
styleUrl: './app.css'
})
export class App implements AfterViewInit, OnInit {
@ViewChild('checkbox', { read: CheckBoxComponent, static: false }) checkbox!: CheckBoxComponent;
@ViewChild('sortable', { read: SortableComponent, static: false }) sortable!: SortableComponent;
ngOnInit(): void {
// onInit code.
}
ngAfterViewInit(): void {
// afterViewInit code.
this.init();
}
init(): void {
// init code.
const that = this;
document.getElementById('handle')?.addEventListener('change', function (event: CustomEvent) {
if (event.detail.value) {
that.sortable.dragMode = 'handle';
that.sortable.handleVisibility = 'visible';
}
else {
that.sortable.dragMode = 'item';
}
} as EventListener);
}
}
Boot the app with bootstrapApplication from src/main.ts and an ApplicationConfig in src/app/app.config.ts as generated by the CLI.
5 Template (standalone)
Use your markup in src/app/app.html (or inline template). Bind properties and events on smart-sortable as needed:
<em>Drag and drop to change list order</em>
<smart-sortable #sortable id="sortable"
items="li">
<ol>
<li>Strawberries</li>
<li>Mango</li>
<li>Watermelon</li>
<li>Apples</li>
<li>Bananas</li>
<li>Grapes</li>
<li>Pineapples</li>
<li>Oranges</li>
<li>Raspberries</li>
<li>Peaches</li>
<li>Cherries</li>
<li>Kiwi</li>
<li>Blueberries</li>
<li>Pomegranate</li>
<li>Lemons</li>
</ol>
</smart-sortable>
<div class="options">
<smart-check-box #checkbox id="handle"><code>drag-mode="handle"</code>
</smart-check-box>
</div>
6 NgModule bootstrap (also supported)
Same npm package and angular.json styles as steps 1-2. Put SortableModule on your NgModule.imports instead of @Component.imports, and bootstrap with bootstrapModule(AppModule).
The demo sources bundled for this widget use standalone only (there is no app.module.ts in that folder). NgModule is fully supported: put SortableModule from smart-webcomponents-angular/sortable on NgModule.imports, make your root component non-standalone (remove standalone: true and move widget modules from @Component.imports to the module), and bootstrap with platformBrowserDynamic().bootstrapModule(AppModule).
Minimal main.ts + app.module.ts pairing (adjust paths to match your CLI layout):
src/main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
platformBrowserDynamic().bootstrapModule(AppModule).catch((err) => console.error(err));
src/app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { SortableModule } from 'smart-webcomponents-angular/sortable';
@NgModule({
declarations: [ AppComponent ],
imports: [ BrowserModule, SortableModule ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
Reuse the template and class logic from steps 4-5 in AppComponent, configured for declarations + NgModule.imports instead of a standalone @Component.
Run
ng serve or npm start - then open http://localhost:4200/.
Smart UI for Angular - full documentation
Accessibility
The Sortable component follows WAI-ARIA best practices:
- Keyboard navigation - Tab, Arrow keys, Enter, and Escape are supported
- ARIA roles - Appropriate roles and labels are applied automatically
- Focus management - Visible focus indicators for keyboard users
- Screen readers - State changes are announced to assistive technology
- High contrast - Supports Windows High Contrast Mode and forced colors
For custom labeling, set aria-label or aria-labelledby attributes on the component.
Supported stacks: Smart UI targets Angular 17+, React 18+, Vue 3+, Node 18 LTS, and evergreen browsers; pin exact package versions to your org policy.
