Creating a Smooth Animated Menu with React and Framer Motion

Creating a Smooth Animated Menu with React and Framer Motion

Introduction

Building an intuitive and engaging user experience often involves adding motion to UI elements, making the interface feel more dynamic. In this post, I’ll guide you through how I built a menu with smooth, staggered animations using React and Framer Motion. By leveraging these technologies, I achieved a polished interaction flow, enhancing the menu’s functionality and visual appeal.

Here’s how I approached the task.

Tools and Libraries

For this project, I used:

• React: To structure and manage the UI components using custom hooks paradigm.
• Framer Motion: A powerful library for animations in React, enabling declarative and complex animations with ease.
• TypeScript: For adding type safety to the components.

Setting up the Component

The main component, AnimatedMenuButtons is responsible for rendering the menu items and handling their animation states. Here’s a breakdown of the key parts of the code:

1. Component Props

The component takes in three main props:

• menuItems: An array of menu items.
• MenuButton: A custom React component for rendering the menu buttons.

Code snippet:

interface Props {
  menuItems: any[];
  MenuButton: React.FC<any>;
}

2. Animation Setup

Using Framer Motion’s motion and stagger features, I set up a staggered animation to display the menu items sequentially, creating a smooth transition. The staggerMenuItems function delays the appearance of each list item by 0.24 seconds.

Code snippet:

const staggerMenuItems = stagger(0.24, { startDelay: 0.05 });

This creates a clean, staggered animation where each button slides into view after a short delay and disappear the same way upon click.

3. Handling Animations

I used the useAnimate hook from Framer Motion to control the animation. The animate function handles the transitions for the menu items. Initially, each menu item (li) starts with zero opacity and is translated 200px to the right, which then animates to full opacity and its original position.

animate(
  "li",
  { opacity: 1, translateX: 0 },
  {
    duration: 0.8,
    delay: staggerMenuItems,
  }
);

4. Click Animation

When a menu item is clicked, the clickHandler triggers an animation where the item fades out and slides back to the right. This animation runs before triggering the onClick event provided by the menu item.

const clickHandler = (onClick: () => void) => {
  animate(
    "li",
    { opacity: 0, translateX: 200 },
    {
      duration: 0.8,
      delay: staggerMenuItems,
      onComplete: () => {
        onClick && onClick();
      },
    }
  );
};

This approach ensures the button clicks are animated smoothly, providing a more immersive experience for the user.

Rendering the Menu Items

Each menu item is rendered inside a motion.li component, where the initial animation state is defined. The onClick event is passed down to trigger the clickHandler, which runs the animation before executing the item's click logic.

Code snippet:

<motion.li
  key={index}
  initial={{
    opacity: 0,
    translateX: 200,
  }}
  onClick={() => clickHandler(item.onClick)}
>
  <MenuButton {...item} />
</motion.li>

Conclusion

Using Framer Motion in React made it straightforward to build an interactive menu with smooth animations. The ability to easily control animation sequences, such as staggered entrances and exits, adds a layer of sophistication to the UI.

If you’re looking to enhance your next project with modern animations, I highly recommend giving Framer Motion a try. It’s incredibly versatile, and with just a few lines of code, you can transform a static interface into something dynamic and engaging.
