Theming

The Menu component is a multipart component. The styling needs to be applied to each part specifically.

To learn more about styling multipart components, visit the Component Style page.

Anatomy

• A: button
• B: list
• C: item
• D: groupTitle
• E: command
• F: divider

Theming properties

The properties that affect the theming of the Menu component are:

• variant: The visual variant of the component. There is no default applied.
• size: The size of the component. There is no default applied.

Theming utilities

• createMultiStyleConfigHelpers: a function that returns a set of utilities for creating style configs for a multipart component (definePartsStyle and defineMultiStyleConfig).
• definePartsStyle: a function used to create multipart style objects.
• defineMultiStyleConfig: a function used to define the style configuration for a multipart component.

import { menuAnatomy } from "@chakra-ui/anatomy";
import { createMultiStyleConfigHelpers, defineStyle } from "@chakra-ui/react";

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(menuAnatomy.keys);

Customizing the default theme

import { menuAnatomy } from "@chakra-ui/anatomy";
import { createMultiStyleConfigHelpers, defineStyle } from "@chakra-ui/react";

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(menuAnatomy.keys);

// define the base component styles
const baseStyle = definePartsStyle({
  // define the part you're going to style
  button: {
    // this will style the MenuButton component
    fontWeight: "medium",
    bg: "teal.500",
    color: "gray.200",
    _hover: {
      bg: "teal.600",
      color: "white",
    },
  },
  list: {
    // this will style the MenuList component
    py: "4",
    borderRadius: "xl",
    border: "none",
    bg: "teal.500",
  },
  item: {
    // this will style the MenuItem and MenuItemOption components
    color: "gray.200",
    _hover: {
      bg: "teal.600",
    },
    _focus: {
      bg: "teal.600",
    },
  },
  groupTitle: {
    // this will style the text defined by the title prop
    // in the MenuGroup and MenuOptionGroup components
    textTransform: "uppercase",
    color: "white",
    textAlign: "center",
    letterSpacing: "wider",
    opacity: "0.7",
  },
  command: {
    // this will style the text defined by the command
    // prop in the MenuItem and MenuItemOption components
    opacity: "0.8",
    fontFamily: "mono",
    fontSize: "sm",
    letterSpacing: "tighter",
    pl: "4",
  },
  divider: {
    // this will style the MenuDivider component
    my: "4",
    borderColor: "white",
    borderBottom: "2px dotted",
  },
});
// export the base styles in the component theme
export const menuTheme = defineMultiStyleConfig({ baseStyle });

After customizing the input theme, we can import it into our theme file and add it in the components property:

import { extendTheme } from "@chakra-ui/react";
import { menuTheme } from "./components/Menu";

const theme = extendTheme({
  components: {
    Menu: menuTheme,
  },
});

export default theme;

This is a crucial step to make sure that any changes we make to the menu theme are applied.

Adding a custom size

Let's assume we want to include an extra large menu size. Here's how we can do that:

import { menuAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers, defineStyle } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(menuAnatomy.keys)

// define custom styles
const lg = defineStyle({
  fontSize: 'md',
  my: '1',
})

const xl = defineStyle({
  fontSize: 'lg',
  px: '4',
  py: '2',
})

// define custom sizes
const sizes = {
  // apply custom styles to parts
  xl: definePartsStyle({ button: xl, item: xl, groupTitle: lg, command: xl }),
}

// export the sizes in the component theme
export const menuTheme = defineMultiStyleConfig({ sizes })

// now we can use the new `xl` size
<Menu size="xl" ... />

Every time you add anything new to the theme, you need to run the CLI command to get proper autocomplete in your IDE. You can learn more about the CLI tool here.

Adding a custom variant

Let's assume we want to include some custom variants to create a pill-shaped menu bar. Here's how we can do that:

import { menuAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers, defineStyle } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(menuAnatomy.keys)

// define custom variants
const variants = {
  roundLeft: {
    button: {
      borderLeftRadius: 'full',
      pl: '6',
    },
  },
  roundRight: {
    button: {
      borderRightRadius: 'full',
      pr: '6',
    },
  },
}

// export the custom variants in the component theme
export const menuTheme = defineMultiStyleConfig({ variants })

// now we can use the new `roundLeft` and `roundRight` variants
<Menu variant="roundLeft" ... />
<Menu variant="roundRight" ... />

Changing the default properties

Let's assume we want to change the default size and variant of every menu in our app. Here's how we can do that:

import { menuAnatomy } from "@chakra-ui/anatomy";
import { createMultiStyleConfigHelpers, defineStyle } from "@chakra-ui/react";

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(menuAnatomy.keys);

// define which sizes and variants are applied by default
const defaultProps = {
  // in this example, we will only set a default size
  size: "xl",
};

// export the default properties in the component theme
export const menuTheme = defineMultiStyleConfig({ defaultProps });

Showcase

import { ChakraProvider, extendTheme } from "@chakra-ui/react";
import Menu from "./menu";
import { menuTheme } from "./menu-theme";

const theme = extendTheme({
  components: {
    Menu: menuTheme,
  }
});

const App = () => {
  return (
    <ChakraProvider theme={theme}>
      <Menu />
    </ChakraProvider>
  );
}

export default App;
