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_kit::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.
