v-show-slide

A Vue.js directive for animating an element to and from height: auto.

There is no pure CSS way to animate an element to or from height: auto. This Vue.js directive solves this. It works the same way as v-show but will show the element with a sliding animation. Duration and easing can be defined on the directive.

Installation

Yarn

yarn add v-show-slide

NPM

npm install v-show-slide --save

Install the Vue plugin

In your main JS file first import this plugin

import VShowSlide from 'v-show-slide'

Install the plugin

Vue.use(VShowSlide)

Usage

Once the plugin is installed the v-show-slide directive can be used in any of your components. This directive works the same way as v-show. If the value is true the element will slide open, if the value is false the element will slide closed.

Example:

<template>
  <div id="app" class="app">
    <ul v-show-slide="featuresOpen" class="features">
      <li>Aliquam lorem</li>
      <li>Praesent porttitor nulla vitae posuere</li>
      <li>Suspendisse nisl elit rhoncus</li>
      <li>Donec mi odio faucibus</li>
      <li>Curabitur suscipit suscipit</li>
    </ul>
    <button @click="toggleFeatures" class="toggle-features">{{ featuresOpen ? 'Hide Features' : 'View Features' }}</button>
  </div>
</template>
<script>
export default {
  name: 'App',
  data () {
    return {
      featuresOpen: false
    }
  },
  methods: {
    toggleFeatures () {
      this.featuresOpen = !this.featuresOpen
    }
  }
}
</script>

Defining duration and easing

By default duration is set to 300ms and easing is set to ease.

To override this duration and easing can be defined directly on the directive. Duration should be defined in milliseconds. Built in easing options are: linear, ease, ease-in, ease-out, ease-in-out

Duration and easing can be set in this format v-show-slide:duration:easing

Example:

<ul v-show-slide:400:ease-in="featuresOpen" class="features">
  <li>Aliquam lorem</li>
  <li>Praesent porttitor nulla vitae posuere</li>
  <li>Suspendisse nisl elit rhoncus</li>
  <li>Donec mi odio faucibus</li>
  <li>Curabitur suscipit suscipit</li>
</ul>

Custom easing

If you want to define custom easing using cubic-bezier this can be done when installing the plugin. Pass an options object as the second parameter in Vue.use.

Example:

Vue.use(VShowSlide, {
  customEasing: {
    exampleEasing: 'cubic-bezier(0.68, -0.55, 0.265, 1.55)'
  }
})

Your custom easing can then be used like so (make sure to convert easing name to kebab-case):

v-show-slide:400:example-easing
