In the fast-evolving world of mobile app development, user experience is paramount. One such interaction enhancing the experience is the expandable card. These cards are commonly seen in popular applications like Instagram and YouTube, providing seamless transitions between different views. In this guide, we’ll explore how to create expandable cards using Ionic React coupled with Framer Motion—a powerful library for animations in React applications.

Understanding Expandable Cards and Shared Element Transitions

What Are Expandable Cards?

Expandable cards are UI components that allow users to view additional information without leaving the current screen. When tapped, they expand to reveal more content, providing a smooth visual transition. This not only keeps users engaged but also helps in maintaining contextual relevance.

Importance of Shared Element Transitions

Shared element transitions help in creating an association between two views, enhancing user awareness of the navigation state. For example, when a user taps on a photo in a grid layout, the photo expands smoothly into a full-screen view, signaling a direct relationship between the two states. This approach significantly improves the user experience and adds a layer of sophistication to your application.

Setting Up Your Ionic React Application

To begin our journey of creating expandable cards, we need to set up an Ionic React application and install Framer Motion.

Step 1: Create a New Ionic React App

Start by creating a new Ionic React application. You can do this via the command line with the following command:

ionic start myExpandableCardApp tabs --type=react

Step 2: Install Framer Motion

After the application is created, navigate into the project directory and install Framer Motion:

npm install framer-motion

Step 3: Removing Unnecessary Code

Once your app is set up, remove unused imports and set up your home component. For simplicity, we will use IonHeader to create a consistent styling between Android and iOS.

Building the Expandable Card Component

Creating the Layout

We’ll now create a layout that will host our list of cards. Each card will expand into a pop-up view when selected. Begin by structuring your components:

1. Container Setup: Create a container div for your list and a separate one for the pop-up layer.
2. CSS Grid: Use CSS Grid to stack the content layers. Set the display to grid for managing layouts effectively.

Adding Content to the List

Fill your list with example data to ensure you have content to work with. Here’s an outline of the code structure:

const posts = [
  { id: 1, image: 'image1.jpg', name: 'Post Title 1' },
  { id: 2, image: 'image2.jpg', name: 'Post Title 2' },
];

return (
  <IonList>
    {posts.map(post => (
      <IonCard key={post.id} onClick={() => setSelectedPost(post)}>
        <IonImage src={post.image} />
        <IonText>{post.name}</IonText>
      </IonCard>
    ))}
  </IonList>
);

This will give you a series of cards to interact with.

Styling the Cards

Essential CSS styling is crucial for making your cards visually appealing. Add styling for the IonCard, IonText, and other elements to achieve the desired look:

ion-card {
  margin: 10px;
  width: 100%;
}

ion-text {
  font-size: 1.5rem;
  font-weight: 600;
}

Implementing Animations with Framer Motion

Transition Effects

To create the shared element transition, we will use Framer Motion’s motion components. Begin by wrapping our card components with motion.div, which allows Framer Motion to handle the animations.

Code Examples:

<motion.div layoutId={`card-${post.id}`}>  
  {/* Card Content Here */}
</motion.div>

Similarly, wrap your pop-up component:

{selectedPost && (
  <motion.div layoutId={`card-${selectedPost.id}`}>  
    <IonImage src={selectedPost.image} />
    <IonText>{selectedPost.name}</IonText>
  </motion.div>
)}

These layout IDs will enable Framer Motion to animate between states seamlessly.

Adding Fade-In and Slide Effects

To enhance the transition effect, apply fade-in and slide animations:

1. Set initial properties for your components:

<motion.div
  initial={{ opacity: 0, y: 20 }}
  animate={{ opacity: 1, y: 0 }}
  exit={{ opacity: 0, y: 20 }}
>

2. Manage these transitions for both the card and the pop-up layer. Use variants to define animations easily and coherently.

Final Touches and Conclusion

After you’ve integrated all the components and animations outlined, test your application. Ensure that the expandable cards behave as expected, transitioning smoothly into full-screen views with attractive animations.

Summary

In this article, we’ve explored how to create expandable cards using Ionic React and Framer Motion. Incorporating shared element transitions can significantly enhance user engagement and maintain contextual relevance within your app. With the setup and code provided, you’re now equipped to implement this feature effectively in your projects.
