Radio Group

Groups radio items and provides keyboard navigation for a single selection.

Like every gpui-base primitive, Radio Group supplies behavior and semantic structure without imposing a product visual language. Apply GPUI styles and compose the exported parts to match your design system.

Example

The single native Cargo entrypoint selects this primitive from the shared showcase implementation. The same showcase is compiled once for the WASM preview above.

cargo run -p gpui-base --example components -- radio-group

Import

use gpui_base::{Radio, RadioGroup};

Anatomy and API

The example composes Radio, RadioGroup. GPUI's standard styling and event traits provide presentation; these base types provide the interaction structure.

The authoritative module is components/radio_group.rs. Native and browser previews compile this same file.

State and events

The group coordinates one selected value and keyboard movement; Radio renders each option.

Keep controlled state on the parent render type or in a GPUI entity. Update it in callbacks and call cx.notify(); do not recreate persistent entities during every render.

Complete Rust example

The complete implementation used by the runnable showcase is embedded directly from Rust source:

use gpui::{
    Context, IntoElement, ParentElement as _, Styled as _, div, prelude::FluentBuilder as _, px,
};
use gpui_base::{Radio, RadioGroup};

use super::super::BaseShowcase;

impl BaseShowcase {
    pub(in super::super) fn radio_group(&self, cx: &mut Context<Self>) -> impl IntoElement {
        let entity = cx.entity().downgrade();
        RadioGroup::new("example-radio-group")
            .w_56()
            .text_xs()
            .flex()
            .flex_col()
            .gap_2()
            .child(self.radio(cx))
            .child(
                Radio::new("express-radio")
                    .checked(self.radio_selected == 1)
                    .on_change(move |next, _, _, cx| {
                        if next {
                            _ = entity.update(cx, |this, cx| {
                                this.radio_selected = 1;
                                cx.notify();
                            });
                        }
                    })
                    .flex()
                    .items_start()
                    .gap_2()
                    .child(
                        div()
                            .mt(px(2.))
                            .flex()
                            .items_center()
                            .justify_center()
                            .size(px(14.))
                            .border_1()
                            .border_color(super::example_rgb(0x171717))
                            .when(self.radio_selected == 1, |this| {
                                this.child(div().size(px(6.)).bg(super::example_rgb(0x171717)))
                            }),
                    )
                    .child(
                        div().child("Express").child(
                            div()
                                .text_xs()
                                .text_color(super::example_rgb(0x737373))
                                .child("Next business day"),
                        ),
                    ),
            )
            .child(
                Radio::new("pickup-radio")
                    .disabled(true)
                    .flex()
                    .items_start()
                    .gap_2()
                    .opacity(0.45)
                    .child(
                        div()
                            .mt(px(2.))
                            .size(px(14.))
                            .border_1()
                            .border_color(super::example_rgb(0x171717)),
                    )
                    .child(
                        div()
                            .child("Local pickup")
                            .child(div().text_xs().child("Currently unavailable")),
                    ),
            )
    }
}

The command above supplies application initialization, window creation, and shared BaseShowcase state.

Accessibility

Label the group, expose one checked item, and support arrow keys among enabled choices.

Notes

Use stable element IDs where accepted. Verify focus, hover, active, selected, disabled, reduced-motion, and high-contrast appearances in the consuming design system.
