Add Radio Button Component

[jainambarbhaya1509]

Feature request: Radio button component

Is your feature request related to a problem?
Oat UI currently lacks a native radio button component. Developers need to either style raw <input type="radio"> elements manually or reach for external solutions, which breaks the consistency of the design system.

Describe the feature
Add a styled radio button component that fits Oat UI's semantic, classless philosophy. It should cover common usage patterns out of the box:

• Default stacked list
• With supporting description text
• Inline / horizontal layout
• Card-style radio (bordered tile that activates on click)
• Disabled state

Expected behavior

• Styled via Oat's existing CSS variables and tokens — no extra classes needed
• Works with native <input type="radio"> semantics
• Accessible: keyboard navigable, correct ARIA roles
• Consistent with existing form elements (checkbox, switch, etc.)

Additional context
This would round out the form elements section and make Oat UI a more complete solution for form-heavy UIs.

Developers need to either style raw

Hi @jainambarbhaya1509. Oat styles the native radio input. Looks like this:

This covers the significant majority of radio button usage. Anything beyond that (card-like-look etc.), if someone needs, can be easily custom-styled. It doesn't make sense to ship that in the core.

Please do share visual samples of what you've in mind and maybe we could document those in the Recipes docs page.

What would something like this look like?

[knadh]

• Inline horizontal is already in the demo (.hstack)
• Vertical/list is similar (.vstack)

These aren't components, just compositions/presentations. Card will require some custom styling, but we can just document that on the recipes page. Feel free to send a PR for that.

Noted, will send a PR.
