IMPORTANT: The Material Web Components are a work in progress and subject to major changes until 1.0 release.

Radio buttons allow the user to select one option from a set. Use radio buttons when the user needs to see all available options.

Installation

npm install @material/mwc-radio

NOTE: The Material Web Components are distributed as ES2017 JavaScript Modules, and use the Custom Elements API. They are compatible with all modern browsers including Chrome, Firefox, Safari, Edge, and IE11, but an additional tooling step is required to resolve bare module specifiers, as well as transpilation and polyfills for Edge and IE11. See here for detailed instructions.
