Getting Started

CDN

Use the built files from npm from https://unpkg.com/progress-steps-webcomponent@latest

<!-- For example, use a CDN and replace 'latest' with your intended version -->
<link rel="stylesheet" href="https://unpkg.com/progress-steps-webcomponent@latest/dist/progress-steps.min.css"/>
<script src="https://unpkg.com/progress-steps-webcomponent@latest/dist/progress-steps.min.js"></script>

Manual

To build yourself, clone the repo, and run

npm i
npm run build

And use the dist/progress-steps.min.js and dist/progress-steps.min.css files

Configuration

View the example above for a complete working example. Add the component anywhere in your html:

<progress-steps id="my-steps"></progress-steps>

Then initialize the control

// Find the control
let myStepper = document.querySelector('#my-steps');

// And initialize it
myStepper.init({
	steps: [{ name: 'Step 1' }, { name: 'Step 2' }, { name: 'Step 3' }],
});

Step configuration

You can disable steps by setting disabled to true. You can attach any custom property to a step that you wish. When programmatically fetching the step later, those values can be retrieved and used. For example, you might attach custom IDs/GUIDs to them, so that when a step is changed, you can act upon the ID of that step:

myStepper.init({
	steps: [
		{ name: 'Step 1', myCustomId: 1 },
		{ name: 'Step 2', myCustomId: 2 },
		{ name: 'Step 3', myCustomId: 3 },
		{ name: 'Step 4', myCustomId: 4 },
		{ name: 'Step 5', myCustomId: 5, disabled: true },
		{ name: 'Step 6', myCustomId: 6, disabled: true },
	],
	events: {
		onStepChanged: function (stepNumber, stepObj) {
			console.log(`Step changed to ${stepNumber}!`);
			let newId = stepObj.myCustomId;
			// [Act upon newId here]
		},
	},
});
