Getting Started with ButtonGroup Web Component

Smart UI Web Components work with current evergreen browsers and Node 18+ for local tooling; pin package versions to match your project policy.

Smart UI is distributed as the smart-webcomponents NPM package. You can also use the full download from the Download page.

Quick start

  1. Install the package:

    npm install smart-webcomponents

  2. Load the ButtonGroup module (ES module script):

    <script type="module" src="node_modules/smart-webcomponents/source/modules/smart.buttongroup.js"></script>

  3. Add the default stylesheet (prefer angular.json / bundler entry in app codebases; for plain HTML use a link):

    <link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

  4. Add markup in one of two ways - semantic custom element (the component tag is in your HTML) or a host div (you mount programmatically with appendTo):

    Semantic element (id matches the selector in Smart()):

    <smart-button-group id="buttongroup"></smart-button-group>

    Host container (id matches appendTo on Smart.ButtonGroup):

    <div id="buttongroupContainer"></div>

  5. Initialize after the module loads: define a const buttongroupOptions object, then either bind with Smart('#buttongroup', ...) on the semantic tag or use new Smart.ButtonGroup({ ...buttongroupOptions, appendTo: '#buttongroupContainer' }) on the host div:

    <script type="module">
	import 'node_modules/smart-webcomponents/source/modules/smart.buttongroup.js';

	const buttongroupOptions = {};

	// Option A - semantic <smart-button-group> with id="buttongroup"
	Smart('#buttongroup', class {
		get properties() {
			return buttongroupOptions;
		}
	});

	// Option B - host div id="buttongroupContainer"
	// const buttongroupInstance = new Smart.ButtonGroup({
	// 	...buttongroupOptions,
	// 	appendTo: '#buttongroupContainer'
	// });

	// Option C - constructor(selector, options), then append the returned element yourself
	// const myButtonGroup = new Smart.ButtonGroup('#buttongroup', buttongroupOptions);
	// document.body.appendChild(myButtonGroup);
</script>

    Uncomment Option B when you use the host div; use Option A when you use the semantic element. The Runtime cookbook also documents new Smart.ButtonGroup('#buttongroup', buttongroupOptions) with appendChild, and document.createElement('smart-button-group') with .props or Object.assign (all are valid patterns; do not combine overlapping patterns for the same instance unless you intend multiple components).

  6. Serve the folder over HTTP (or use your bundler dev server) and open the page.

Runtime cookbook

Alternative creation patterns and imperative APIs. These are all valid ways to create Smart UI components: semantic markup + Smart(); new Smart.ButtonGroup({ ...options, appendTo: '#...' }); new Smart.ButtonGroup('#buttongroup', buttongroupOptions) plus appendChild on the returned element; and document.createElement('smart-button-group') then assigning options via .props or Object.assign on the element.

Constructor with a selector string and options, then append the returned element (for example const myButtonGroup = new Smart.ButtonGroup('#buttongroup', buttongroupOptions)):

	const buttongroupOptions = {};
	const myButtonGroup = new Smart.ButtonGroup('#buttongroup', buttongroupOptions);
	document.body.appendChild(myButtonGroup);

Create with document.createElement('smart-button-group'), assign properties (same as any custom element), then append:

	const buttongroupOptions = {};
	const buttongroup = document.createElement('smart-button-group');
	Object.assign(buttongroup, buttongroupOptions);
	document.body.appendChild(buttongroup);

Host on a div with appendTo (import the module, then instantiate when the document is ready; the container id must match appendTo):

	import "../../source/modules/smart.buttongroup.js";

	document.readyState === 'complete' ? init() : window.addEventListener('load', init);

	function init() {
		const buttongroupOptions = {};
		const buttongroup = new Smart.ButtonGroup({
			...buttongroupOptions,
			appendTo: '#buttongroupContainer'
		});
	}

Append to the DOM:

const container = document.getElementById('buttongroup-container');
container.appendChild(buttongroup);

Remove from the DOM:

buttongroup.remove();

Set a property:

buttongroup.disabled = true;
buttongroup.theme = 'dark';

Get a property value:

const isDisabled = buttongroup.disabled;
const currentTheme = buttongroup.theme;

Invoke a method:

buttongroup.refresh();
buttongroup.focus();

Add event listener:

buttongroup.addEventListener('change', (event) => {
    console.log('change triggered:', event.detail);
});

Remove event listener:

const handleButtonGroupEvent = (event) => {
    console.log('change triggered:', event.detail);
};

buttongroup.addEventListener('change', handleButtonGroupEvent);
buttongroup.removeEventListener('change', handleButtonGroupEvent);

Accessibility

The ButtonGroup component follows WAI-ARIA best practices:

For custom labeling, set aria-label or aria-labelledby attributes on the component.
