Multi Level Menu

This document is related to how to create a multi-level menu for refine applications.

What is Multi-level Menu?

The multi-level menu is a great way to organize your sider menu items. You can create groups and sub menus to keep your menu items organized. This makes it easy to find the menu items you are looking for.

Usage

To do this, it is necessary to create an object array with the following resources properties:

src/App.tsx

        <Refine
           ...
            resources={[
                {
                    name: "CMS",
                },
                {
                    name: "posts",
                    parentName: "CMS",
                    list: PostList,
                    create: PostCreate,
                    edit: PostEdit,
                    show: PostShow,
                },
                {
                    name: "category",
                    parentName: "CMS",
                    list: CategoryList,
                    create: CategoryCreate,
                    edit: CategoryEdit,
                    canDelete: true,
                },
            ]}
        />

tip

The parentName you give in the resource objects must be strictly equal to the resource name you want to group under.
A resource given as a group can only have a name and a parentName. They should not have other props such as list, edit, create, etc.

caution

Since your Next.js applications are routing file-based, you need to manage the nested routes yourself. If you use Nested resources only for grouping Menu items in Sider and you don't need nested routes, you can give route option as a single level routing when defining your resource.

pages/_app.tsx

        <Refine
           ...
            resources={[
                {
                    name: "CMS",
                },
                {
                    name: "posts",
                    parentName: "CMS",
                    options: { route: "posts" },
                    list: PostList,
                    create: PostCreate,
                    edit: PostEdit,
                    show: PostShow,
                },
                {
                    name: "category",
                    parentName: "CMS",
                    options: { route: "category" },
                    list: CategoryList,
                    create: CategoryCreate,
                    edit: CategoryEdit,
                    canDelete: true,
                },
            ]}
        />

Headless

If you want to create your multi-level menu without any UI framework integration, useMenu hook gives your resources. The createTreeView helper from refine core allows you to create a tree for your headless sider.

src/components/layout/sider/index.tsx

import { useMenu } from "@pankod/refine-core";

export const Sider: React.FC = () => {
    const { menuItems, selectedKey, defaultOpenKeys } = useMenu();

    // Here create your Sider to your UI choice
};

example output

// console.log(menuItems);
[
    {
        name: "CMS",
        route: "CMS",
        ...
        children: [
            {
                name: "posts",
                route: "CMS/posts",
                ...
                children: [],
            },
            {
                name: "category",
                route: "CMS/category",
                ...
                children: [],
            },
        ],
    },
];

Ant Design

The Sider component allows you to create the groups you want in the sider menu. By default, the sider will group menu items by their top-level heading. However, you can also add sub menu items to each group via parentName.

This gives you more control over the side menu and allows you to customize it to better suit your needs.

Example
