In this post I am going to share awesome Animated Accordion Component for VueJS and GSAP. This Accordion component, written in VueJS. The animations are done with GSAP. You can use this accordion to display multiple content in single block with some cool effect. I personally liked this accordion it makes your vue app more dynamic.
Animated Accordion Component for VueJS and GSAP


app.js

In template just looped the passed props from the VM to the component, to display the template or the design of the accordion.

Vue.component('zz-accordion', {
    props: ['contents'],
    data: function() {
        return {
        }
    },
    methods: {
        expand: function(e, i) {
            e.preventDefault();
 
            let el = this.$refs['accordion-body-' + i][0];
 
            if (this.contents[i].active === false) {
                this.contents[i].active = true;
 
                TweenLite.to(el, 1, {
                    height: el.scrollHeight,
                    ease: Elastic.easeOut.config(1, 0.3)
                });
            } else {
                this.contents[i].active = false;
 
                TweenLite.to(el, 0.5, {
                    height: 0,
                    ease: Bounce.easeOut
                });
            }
        }
    },
    template: `
<div class="accordion">
    <div
        class="accordion-item"
        v-for="content, i in contents"
        v-bind:class="{ 'accordion-active': content.active }"
    >
        <div class="accordion-header">
            <a href="#" v-on:click="expand(event, i)">
                <div class="accordion-header-div">{{ content.title }}</div>
                <div class="accordion-header-div">
                    <div class="accordion-caret"></div>
                </div>

        </div>
        <div class="accordion-body" v-bind:ref="'accordion-body-' + i">
            <div class="accordion-content">{{ content.description }}</div>
        </div>
    </div>
</div>
`
});
