@m3e/chips

The @m3e/chips package provides expressive, accessible chip components for actions, input, filtering, and suggestions, each supporting two appearance variants—outlined and elevated. Use outlined for lightweight, unobtrusive chips such as tags or filters, and elevated for chips that require stronger visual affordance, like assist actions or selected states. These variants help convey interaction weight, visual hierarchy, and contextual emphasis across static and interactive use cases.

> This package is part of M3E monorepo, a unified suite of Material 3 web components. Explore the docs to see them in action.

📦 Installation

``bash
npm install @m3e/chips
`

💻 Editor Integration

This package includes a Custom Elements Manifest to support enhanced editor tooling and developer experience.

$3

To enable autocomplete and hover documentation for @m3e/chips, install the Custom Elements Manifest Language Server extension. It will automatically detect the manifest bundled with this package and surface tag names, attributes, slots, and events in supported files.

Alternately, you can explicitly reference the html-custom-data.json and css-custom-data.json in your workspace settings:

`json
{
"html.customData": ["./node_modules/@m3e/chips/dist/html-custom-data.json"],
"css.customData": ["./node_modules/@m3e/chips/dist/css-custom-data.json"]
}
`

🚀 Native Module Support

This package uses JavaScript Modules. To use it directly in a browser without a bundler, use a module script similar to the following.

`html

`

You also need a module script for @m3e/icon-button and m3e/form-field due to being a dependency.

`html


`

In addition, you must use an import map to include additional dependencies.

`html

`

> For production, use index.min.js, a11y.min.js, and bidi.min.js for faster load times.
