The Menu component in Chakra UI serves as a wrapper, providing essential context, state, and focus management for your menus. It acts as a central hub, facilitating the smooth operation of various menu-related elements. But the power of Chakra UI extends beyond the Menu component alone. Let's explore the components that complement and enhance its functionality:
MenuList: This component serves as a container for your menu items. It ensures proper structuring and organization of your menu content. Remember, the MenuList should always be a direct child of the Menu component.
MenuButton: Acting as the trigger for the menu list, the MenuButton handles the opening and closing of the menu when interacted with. It simplifies the user experience by providing a clear way to access the menu items.
MenuItem: As a direct child of the MenuList, the MenuItem component handles the selection logic for your menu. It allows users to interact with the menu items effortlessly, making their navigation more intuitive.
MenuGroup: If you have related menu items that need to be grouped together, the MenuGroup component comes in handy. It enables you to organize and categorize your menu options, improving the overall user experience.
MenuDivider: Visual separators play a crucial role in menu design, enhancing clarity and structure. The MenuDivider component allows you to create visually appealing menus by adding clear distinctions between items and groups.
MenuOptionGroup: For menus with checkable items like radio buttons or checkboxes, the MenuOptionGroup component simplifies the process. It provides a wrapper to group and manage these selectable options, making it easier for users to make their choices.
MenuItemOption: This component works in conjunction with the MenuOptionGroup, providing the checkable menu item functionality. It allows users to make selections within the menu, creating a cohesive and interactive experience.
Chakra UI's Menu component, along with its complementary components, offers a comprehensive set of tools to elevate your website's menu design. Furthermore, Chakra UI's theming capabilities ensure that your menus seamlessly integrate with your overall design aesthetic.
These components can be imported as follows:
The MenuList component represents the container for the menu items. It is where you define and render individual MenuItem components. In this example, we have four menu items: "Get Coffee," "Take a Walk," "Pet a Dog," and "Meditate."
Accessing Internal State
In this example, instead of directly placing child components within the Menu component, we provide a render prop function as the children. This function receives an object with the isOpen property, which indicates whether the menu is currently open or closed.
Using this isOpen property, we can dynamically update the appearance of the MenuButton component by setting the isActive prop based on the isOpen value. This allows us to style the button differently depending on the menu state.
The render prop function also enables us to customize the content of the MenuButton. In this case, we display "Close" or "Open" text based on the current state. This text is rendered dynamically by utilizing a ternary operator to conditionally display the appropriate label.
Within the render prop function, we continue defining the MenuListcomponent and its child MenuItem components. These represent the dropdown menu items that will be displayed when the menu is open. In this example, we have two menu items: "Do Something" and "Do Something Better," with the latter having a click event handler that triggers an alert when clicked.
By leveraging the render prop function in the Menu component, you can gain more control over the internal state and behavior of the menu, allowing for dynamic rendering and seamless interaction within your application.
Customizing the Menu Button
By utilizing the custom button component with the Menu component, we can create a customized menu trigger with the desired visual appearance and behavior. The menu will now open and close as expected without any type errors.
Letter Navigation Menu
To use the letter navigation functionality, follow these steps. You will notice that the focus automatically moves to the first MenuItem that begins with the letter you typed.
This image menu example is a unique menu component that showcases different images of the renowned actor, Keanu Reeves. Each menu item features a custom image of Keanu Reeves along with a corresponding label.
Inside the MenuList, we have three MenuItem components, each showcasing a different image of Keanu Reeves. The images are fetched from the "placekeanu.com" website with varying URLs to display unique images. Alongside each image, there is a label denoting the specific Keanu Reeves version.
Icon and Command Enhancement
In this customized example, we utilize the Chakra UI Menu component to create a menu with enhanced functionality. The MenuButton, rendered as an IconButton, features the HamburgerIcon and serves as the trigger for the menu. Within the MenuList, we define several MenuItem components. Each MenuItem includes an icon representing the action associated with it, such as AddIcon, ExternalLinkIcon, RepeatIcon, and EditIcon.
Additionally, a command or hotkey is specified for each menu item using the command prop, which provides a convenient way to communicate keyboard shortcuts or commands to the user. By incorporating icons and commands, this menu provides clear visual cues and helps users quickly identify and access specific actions. This approach can be adapted for a variety of use cases, such as productivity tools, text editors, or any application where efficient menu navigation and command execution are essential.
Within the MenuList, we utilize the MenuGroup component to create two distinct groups: Likes and Dislikes. Each group is defined by a title passed as a prop to MenuGroup. Under the Likes group, we have menu items like "Coffee" and "Dark Chocolate." After a MenuDivider, the Dislikes group includes menu items such as "Chicken Liver" and "Mean People."
By employing the MenuGroup component, you can structure your menus in a logical manner, making it easier for users to locate and select the desired options. This approach is particularly useful when organizing complex menus with multiple categories or sections. The MenuGroup component ensures a cohesive and intuitive user experience when navigating through various menu items.
MenuItem as a Link
By incorporating this approach, users can click on the menu items and navigate to the specified URLs or anchor targets. This is particularly useful when building navigation menus or dropdowns that require clickable links as menu options.
Lazy Mounting of Menu Items: YBy default, the Menu component in Chakra UI renders all children of the MenuList to the DOM, even if they are not visible. However, there might be situations where you want to defer the rendering of each menu item until the menu is actually opened. To achieve this, you can utilize the isLazy prop. This feature is particularly useful if you aim to optimize the performance of your Menu or if you need to make network calls or perform certain actions on mount that should only occur when the menu is displayed to the user.
Rendering Menu in a Portal: To achieve greater flexibility and control over the placement and behavior of menus, Chakra UI provides the option to render menus in a portal. This is accomplished by importing the Portal component and wrapping the MenuList within it. Let's explore the benefits and use cases of rendering menus in a portal.
By utilizing a portal, you gain the ability to render the menu outside of its parent component's DOM hierarchy. This allows you to control the menu's positioning and ensure it appears exactly where desired, even in complex layouts or nested components. It provides greater control over z-index stacking and avoids potential overflow or clipping issues that may occur within parent components.
This can be implemented simply by wrapping the MenuList component inside of a Portal component.
Sorting and Filtering with Menu Option Groups: In Chakra UI, you have the ability to compose a menu for table headers that facilitates sorting and filtering operations. This can be achieved by utilizing the MenuOptionGroup and MenuItemOption components. Let's explore how to leverage these components to create dynamic and interactive menu option groups.
The MenuOptionGroup component allows you to group related menu options together. It acts as a wrapper for the MenuItemOption components, which represent individual options within the group. This approach is particularly useful when dealing with table headers that require sorting or filtering capabilities.
