Tabs

A tab list and accessible tab controls with controlled selection.

Like every gpui-base primitive, Tabs 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 -- tabs

Import

use gpui_base::{Tab, Tabs};

Anatomy and API

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

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

State and events

The parent owns selected index/value; each tab reflects it and click handlers update the parent.

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 super::*;

impl BaseShowcase {
    pub(in super::super) fn tabs(&self, cx: &mut Context<Self>) -> impl IntoElement {
        let selected = self.selected_tab;
        div()
            .w_72()
            .text_xs()
            .border_1()
            .border_color(super::example_rgb(0xd4d4d4))
            .child(
                Tabs::new("example-tabs")
                    .flex()
                    .px_2()
                    .pt_1()
                    .border_b_1()
                    .border_color(super::example_rgb(0xd4d4d4))
                    .children(
                        ["Overview", "Activity", "Settings"]
                            .into_iter()
                            .enumerate()
                            .map(|(index, label)| {
                                let entity = cx.entity().downgrade();
                                Tab::new(index)
                                    .selected(self.selected_tab == index)
                                    .px_2()
                                    .h_7()
                                    .flex()
                                    .items_center()
                                    .border_b_2()
                                    .border_color(if self.selected_tab == index {
                                        super::example_rgb(0x171717)
                                    } else {
                                        super::example_rgb(0xffffff)
                                    })
                                    .when(self.selected_tab == index, |this| {
                                        this.font_weight(gpui::FontWeight::SEMIBOLD)
                                    })
                                    .on_click(move |_, _, cx| {
                                        _ = entity.update(cx, |this, cx| {
                                            this.selected_tab = index;
                                            cx.notify();
                                        });
                                    })
                                    .child(label)
                            }),
                    ),
            )
            .child(
                div().min_h_20().p_3().child(match selected {
                    0 => div().child("Workspace overview").child(
                        div()
                            .mt_1()
                            .text_color(super::example_rgb(0x737373))
                            .child("12 components · 4 contributors · updated today"),
                    ),
                    1 => div().child("Recent activity").child(
                        div()
                            .mt_1()
                            .text_color(super::example_rgb(0x737373))
                            .child("Button example was updated 8 minutes ago."),
                    ),
                    _ => div().child("Project settings").child(
                        div()
                            .mt_1()
                            .text_color(super::example_rgb(0x737373))
                            .child("Manage notifications and member access."),
                    ),
                }),
            )
    }
}

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

Accessibility

Associate tabs with panels, expose selection, and support keyboard traversal.

Notes

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