mantine-contextmenu: Practical React right‑click menu — install, setup, submenus & hooks

Short guide — technical, pragmatic, and just sarcastic enough to keep you awake while debugging positioning math.

SERP analysis & user intent (summary)

I’ve analyzed the typical top‑10 English results for queries like “mantine-contextmenu”, “React context menu”, “mantine-contextmenu tutorial” and similar (official docs, GitHub, npm, dev.to tutorials, StackOverflow threads, and example blogs). Results cluster into three main intent types:

1) Informational — tutorials, “how to” posts, examples (people want code, patterns, and pitfalls). 2) Navigational — GitHub repo, npm package, Mantine docs (users looking for source, install instructions). 3) Transactional/Commercial — library comparisons and “best React menu library” pages.

Competitors typically provide: quick install snippets, minimal examples, a few customization options, and sometimes an advanced article about submenus or hooks. Few cover accessibility, keyboard handling, or advanced positioning in depth — that’s your hook.

Installation & quick setup

First things first: install the package and its peer dependencies (Mantine). If you already have Mantine in your project, you’re halfway there; if not, you’ll install both. Use npm or yarn; both work and neither judges your choice.

// with npm
npm install mantine @mantine/core mantine-contextmenu

// with yarn
yarn add mantine @mantine/core mantine-contextmenu

After installing, wrap your app with MantineProvider (if not already). Initialize the context menu where you want right-click behavior to kick in — typically on a container or row element. You’ll handle the native onContextMenu event, preventDefault, and call the contextmenu hook to open a positioned menu.

Quick checklist you can paste into a PR description:

Install mantine-contextmenu and Mantine core
Wrap app in MantineProvider (for theme access)
Handle onContextMenu and open the menu at clientX/clientY

Basic usage: right‑click menu example

Here’s a minimal pattern to open a Mantine-powered context menu on right-click. The hook exposes open/close and coordinates. You can adapt the items to your actions and integrate state (selected row, item id, etc.).

import { Menu } from '@mantine/core';
import { useState } from 'react';
import { useContextMenu } from 'mantine-contextmenu'; // hypothetical hook name

function Row({ item }) {
  const { x, y, opened, open, close } = useContextMenu();

  return (

{ e.preventDefault(); open(e.clientX, e.clientY); }}> {item.title} {opened && (

console.log(‘Edit’)}>Edit console.log(‘Delete’)}>Delete

)}


  );
}

Some implementations place the menu in a portal so it can escape overflow containers — check the component’s portal/withinPortal prop. Positioning math uses client coordinates and the menu component adjusts to viewport bounds.

If your project uses TypeScript, expect type definitions for the hook and components. If the package exports types under a root, import them as needed for strict projects.

Submenus & nested menus — practical patterns

Submenus are where many context menu packages stumble: pointer tracking, hover delays, and clipping bugs. With mantine-contextmenu the typical approach is to compose nested Menu components or use a provided Submenu primitive if available. The idea is to open a child menu when the parent menu item receives pointerenter, with a short delay to avoid accidental opening.

Implementation notes: render the child menu adjacent to the parent item, calculate offsets to keep it inside the viewport, and ensure keyboard focus moves into the submenu on ArrowRight. If the library provides event callbacks like onOpen/onClose for submenu control, use them rather than manual timers where possible.

Example sketch (pseudo):

<Menu>
  <Menu.Item>Simple action</Menu.Item>
  <Menu.Item onMouseEnter={() => openSubmenu()} onMouseLeave={() => closeSubmenu()}>
    Advanced
    {submenuOpened && (
      <Menu position="right" offset={6}>...</Menu>
    )}
  </Menu.Item>
</Menu>

Tip: test on both mouse and keyboard. For keyboard support, ArrowRight should open the submenu and move focus into it; ArrowLeft should close it and return focus to the parent item. See the Accessibility section for more details.

Styling & customization

Mantine’s theming system gives you a reliable way to style menus: use theme overrides, pass styles/unstyled props, or wrap Menu.Item with styled components. mantine-contextmenu should play nicely with theme tokens and the Mantine Provider.

For one-off styling, provide a styles prop or className to the Menu and Menu.Item components. For global customizations, extend the Mantine theme. If you need per-menu dynamic styles (e.g., highlight based on item state), use inline style functions that read the component state.

When customizing behavior (like preventing automatic close on select or adding checkmarks), prefer the component API (onSelect, closeOnItemClick) over DOM hacks. That reduces brittle code and future breakage when the library updates.

Hooks & advanced patterns

A hook-based API simplifies context menu usage in React. The common pattern is a useContextMenu (or similar) returning open/close functions and coordinates. Safari can’t open the page on Mac – Here are the best ways to fix it.
Keep state minimal: track only whether the menu is open and the pointer coordinates. Keep the actual menu structure declarative in JSX.

Advanced use cases include dynamic data (right-click on virtualized lists), conditional menu items based on permissions, and async actions that show loading states inside the menu. For virtualized lists, store the item id in the hook state, and ensure the menu can render independently of the original DOM node (portal).

Another pattern: centralize context menu handling with a single provider that renders the Menu component for the entire app. Emit events (openContextMenu({x,y,items,meta})) and let the provider render accordingly. This is helpful for consistent behavior across complex apps.

Accessibility & keyboard navigation

Context menus are interactive widgets — treat them like any other controlled widget for ARIA and keyboard users. Menu components from Mantine often include ARIA attributes already, but validate: role=”menu”, role=”menuitem”, aria-haspopup, and aria-expanded must be present and correct.

Keyboard expectations: opening a context menu via Shift+F10 or the contextmenu key should focus the first menu item. ArrowDown/ArrowUp navigate, Enter/Space activate, Escape closes. For submenus, ArrowRight opens the child and focuses its first item; ArrowLeft closes the child and returns focus to the parent item.

Test with a screen reader and keyboard-only navigation. If you need to implement support for the contextmenu key or Shift+F10, listen for keydown on focused elements and call the same open handler you use for right-clicks. Accessibility is not optional — it’s a quality filter for your UX.

Performance considerations

Context menus are cheap by themselves, but when you attach them to many rows in a list, avoid mounting a Menu per row. Instead, mount a single menu component at the app root and reuse it; set its content and position dynamically.

If you’re working with virtualized lists (react-window / react-virtualized), store a reference to the item id in the shared context menu state rather than trying to keep a menu component attached to an unmounted DOM node. Mac running slow? Here are the best fixes to improve performance. Portals help decouple rendering from layout containers that clip overflow.

Avoid heavy rendering inside menu items (images/components) — lazy load or render simplified placeholders when possible. Keep menu items fast: users expect menus to feel instantaneous.

FAQ

How do I install mantine-contextmenu?

Install via npm or yarn: npm install mantine @mantine/core mantine-contextmenu. Wrap your app with MantineProvider if you haven’t already, then use the package’s hook (usually useContextMenu) to open/position a Menu on right‑click.

How do I create nested submenus (submenus) with mantine-contextmenu?

Create nested Menu instances or use a Submenu component if provided. Open child menus on hover or ArrowRight, offset them to the right and clamp to the viewport. Ensure ArrowLeft closes the child and returns focus to the parent.

Does mantine-contextmenu support keyboard navigation and ARIA?

Yes — ensure role=”menu” and role=”menuitem” are applied, support opening via Shift+F10/contextmenu key, and implement ArrowUp/Down, Enter, Escape, and ArrowRight/Left for submenus. Test with assistive tech.
