JavaScript Action Sheet

<Actionsheet /> — iOS-style action sheet on the Modal primitive.

Faithful port of @lemonadejs/actionsheet (v5): a bottom sheet over a dimmed backdrop, listing GROUPS of actions — each group a white rounded card, each action a full-width button; action: ‘cancel’ renders red. Built ON Modal (headerless, position bottom, backdrop) the way every v5 floating surface was built on @lemonadejs/modal.

v5 → v6 mapping: visible → bind (the open state, two-way); show()/hide() → api.open()/close()/toggle() + isOpened(); actions keeps its name and its shape ([{ options: [{ title, action, className, onclick }] }]) and is LIVE — swap the array, the sheet re-renders (v5 show(options) merged properties; in v6 you write the state instead). Per-option onclick still receives the option object. The sheet does NOT auto-close on a pick — exactly like v5, closing is the consumer’s call.

Added: closable (backdrop click closes — v5 shipped no close affordance at all; Escape ALWAYS closes regardless: the backdrop Modal traps Tab inside the sheet, so the keyboard must keep an exit); title/message header card (v5 shipped the CSS for .jactionsheet-title/-message but never rendered them — resurrected). Dropped: the v5 slide-bottom-out exit animation (it gated closing on animationend; v6 closes immediately, the slide-IN stays, pure CSS). onclose(origin): ‘backdrop’ | ‘escape’ | ‘api’.

Example

live

LemonadeJS

import { html, ref } from 'lemonadejs';
import Actionsheet from '@lemonadejs/actionsheet';

const App = (props, { state }) => {
    const sheet = ref();
    const picked = state('');

    const pick = (option) => {
        picked.value = option.title;
        sheet.current.close();
    };

    const actions = [
        { options: [
            { title: 'Share photo', onclick: pick },
            { title: 'Add to album', onclick: pick },
            { title: 'Delete photo', onclick: pick },
        ] },
        { options: [{ title: 'Cancel', action: 'cancel', onclick: pick }] },
    ];

    return html`<div>
        <button onclick="${() => sheet.current.open()}">Photo options</button>
        <p>Picked: <b>${() => picked.value || 'nothing yet'}</b></p>
        <${Actionsheet} ref="${sheet}" actions="${actions}" closable
            title="IMG_2048.jpg" message="Taken 12 Aug 2026, Lisbon" />
    </div>`;
};

Installation

npm install @lemonadejs/actionsheet

import Actionsheet from '@lemonadejs/actionsheet';
import '@lemonadejs/actionsheet/style.css';

Three deployment forms, one component:

html`<${Actionsheet} />`                       // by value (no registration)
setComponents({ Actionsheet });               // then <Actionsheet /> by name anywhere
createWebComponent(Actionsheet);              // <lm-actionsheet> in plain HTML/any framework

Props

Every declared prop arrives as a live state — pass a value for a snapshot or a state for a two-way live wire. Attribute strings are coerced to the declared type.

Events

All event names are lowercase (the platform convention — LJS-305 warns otherwise).

• onopen — sheet opened
• onclose — sheet closed (origin)

API

import { ref } from 'lemonadejs';
const actionsheet = ref();
html`<${Actionsheet} ref="${actionsheet}" />`;
// actionsheet.current.open(...)  ·  actionsheet.current.close(...)  ·  actionsheet.current.toggle(...)  ·  actionsheet.current.isOpened(...)

• open()
• close()
• toggle()
• isOpened()

Styling

All classes follow the lm-actionsheet-* convention; visual variants are data-* attributes on the root. Override freely — there is no styling engine to fight.

Contract

The machine-readable schema ships with the package:

import contract from '@lemonadejs/actionsheet/contract.json';

verify.json carries the conformance proof produced by verify(Actionsheet).
