vue-slide-up-down

Like jQuery's slideUp / slideDown, but for Vue!

Demo: https://codepen.io/danieldiekmeier/pen/YapGWq

Installation

npm i vue-slide-up-down

Usage with Webpack or other module bundlers:

import SlideUpDown from 'vue-slide-up-down'
// or
const SlideUpDown = require('vue-slide-up-down')

Vue.component('vue-slide-up-down', VueSlideUpDown)

Or use the UMD build directly in your browser:

<script type="text/javascript" src="node_modules/vuejs/dist/vue.min.js"></script>
<script type="text/javascript" src="node_modules/vue-slide-up-down/dist/vue-slide-up-down.umd.js"></script>
<script type="text/javascript">
  Vue.component('vue-slide-up-down', VueSlideUpDown);
</script>

Usage

The component takes two props:

• active (Boolean): Whether to show the component (true) or not (false)
• duration (Number): How long the animation is supposed to be, in milliseconds. Defaults to 500.
• timing-function (String): What transition-timing-function should be used. Defaults to ease.
• appear (Boolean): Wether the initial appear of component should be animated. Defaults to true.

Example

<div class="MyContent">
  <h1>Always show this</h1>
  <vue-slide-up-down :active="active" :duration="1000">
    Only show this if "active” is true
  </vue-slide-up-down>
</div>

Also

This currently works by showing the element, measuring the height, setting the height back to 0, and then CSS-transitioning to the target height. This works okay, but is not very performant. If you have other ideas how to make this extremely smooth and good looking, feel free to send issues or pull requests.
