OTP Input

A multi-cell one-time-code input driven by a shared text state.

Like every gpui-base primitive, OTP Input 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 -- otp-input

Import

use gpui_base::{OtpInput, OtpState};

Anatomy and API

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

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

State and events

OtpState owns the complete code and active cell; visual cells share that state.

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};
use gpui_base::OtpInput;

use super::super::BaseShowcase;

impl BaseShowcase {
    pub(in super::super) fn otp_input(&self, cx: &mut Context<Self>) -> impl IntoElement {
        let value: Vec<char> = self.otp.read(cx).value().chars().collect();
        let active = value.len().min(5);

        div()
            .w_56()
            .flex()
            .flex_col()
            .gap_1()
            .text_xs()
            .child(div().text_xs().child("Verification code"))
            .child(
                div().child(
                    OtpInput::new(&self.otp)
                        .flex()
                        .gap_1()
                        .children((0..6).map(|ix| {
                            div()
                                .size_7()
                                .flex()
                                .items_center()
                                .justify_center()
                                .border_1()
                                .border_color(if ix == active {
                                    super::example_rgb(0x171717)
                                } else {
                                    super::example_rgb(0xd4d4d4)
                                })
                                .child(value.get(ix).copied().unwrap_or(' ').to_string())
                        })),
                ),
            )
            .child(
                div()
                    .text_xs()
                    .text_color(super::example_rgb(0x737373))
                    .child("Enter the 6-digit code."),
            )
    }
}

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

Accessibility

Label the whole code, announce length/errors, and support paste.

Notes

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