Easy Accordion Component with VUE JS – Part 3

In the previous parts of this tutorial series, we learned how to create a basic accordion component using VUE JS. In this part, we will add some additional features to our accordion component to make it even more user-friendly and customizable.

Adding Toggle Functionality

One of the most common features of an accordion component is the ability to toggle the open and close state of the accordion item. We can easily achieve this by adding a simple click event to the accordion header.

    
        <div id="app">
            <accordion-item v-for="(item, index) in items" v-bind:key="index">
                <template v-slot:header>
                    <h3 @click="toggleItem(index)">{{ item.title }}</h3>
                </template>
                <template v-slot:content>
                    <p>{{ item.content }}</p>
                </template>
            </accordion-item>
        </div>
    
    

In the above code, we added a click event to the title of each accordion item, which calls the toggleItem method passing the index of the item as an argument. Inside the toggleItem method, we can then toggle the open state of the accordion item based on its index.

Customizing Accordion Styles

Another important aspect of a good accordion component is the ability to customize its styles to fit the design of the website or application. We can achieve this by utilizing the power of VUE JS dynamic CSS classes and inline styles.

    
        <style>
            .accordion {
                border: 1px solid #ccc;
                border-radius: 5px;
            }
            .accordion-item {
                border-bottom: 1px solid #ccc;
                overflow: hidden;
                max-height: 0;
                transition: max-height 0.3s ease;
            }
            .accordion-item.open {
                max-height: 1000px;
                transition: max-height 0.3s ease;
            }
        </style>
    
    

In the above code, we added some basic styles for the accordion container and each accordion item. We also added a special .open class to the accordion item, which increases its max-height to reveal the content when the item is open. We can then dynamically toggle the .open class based on the open state of the accordion item using VUE JS.

Conclusion

By adding toggle functionality and customizing the styles of our accordion component, we have created a more user-friendly and customizable solution for displaying content in a collapsible manner. VUE JS makes it easy to add these features and customize the behavior and appearance of our accordion component based on our specific needs.
