Installation

Usage with Vue 3

<template>
  <div>
    <Toggle v-model="value" />
  </div>
</template>

<script>
  import Toggle from '@vueform/toggle'

  export default {
    components: {
      Toggle,
    },
    data() {
      return {
        value: true
      }
    }
  }
</script>

<style src="@vueform/toggle/themes/default.css"></style>

Using with Vue 2

When using Vue 2 install @vue/composition-api via npm/yarn first:

npm i @vue/composition-api --save-dev

Then install the plugin for Vue:

import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'

Vue.use(VueCompositionAPI)

After that make sure to change the imported Toggle module to:

import Toggle from '@vueform/toggle/dist/toggle.vue2.js'

Using with Nuxt.js

First you need install @nuxtjs/composition-api:

npm i @nuxtjs/composition-api --save

Then you need to enable it as a module in nuxt.config.js:

{
  buildModules: [
    '@nuxtjs/composition-api/module'
  ]
}

After that make sure to change the imported module to Vue 2 version of Toggle:

import Toggle from '@vueform/toggle/dist/toggle.vue2'

For more information on using @nuxtjs/composition-api read their documentation.

Slot	Attributes	Description

Styling with CSS vars

The following CSS variables can be used to customize toggle when using default.css:

--toggle-width: 3rem;
--toggle-height: 1.25rem;
--toggle-border: 0.125rem;
--toggle-font-size: 0.75rem;
--toggle-duration: 150ms;
--toggle-bg-on: #10b981;
--toggle-bg-off: #e5e7eb;
--toggle-bg-on-disabled: #d1d5db;
--toggle-bg-off-disabled: #e5e7eb;
--toggle-border-on: #10b981;
--toggle-border-off: #e5e7eb;
--toggle-border-on-disabled: #d1d5db;
--toggle-border-off-disabled: #e5e7eb;
--toggle-ring-width: 3px;
--toggle-ring-color: #10B98130;
--toggle-text-on: #ffffff;
--toggle-text-off: #374151;
--toggle-text-on-disabled: #9ca3af;
--toggle-text-off-disabled: #9ca3af;
--toggle-handle-enabled: #ffffff;
--toggle-handle-disabled: #f3f4f6;

Override them globally:

:root {
  --toggle-bg-on: red;
  --toggle-border-on: red;
}

Or on an instance level:

<Toggle v-model="value" class="toggle-red" />
<Toggle v-model="value" class="toggle-blue" />

.toggle-red {
  --toggle-bg-on: red;
  --toggle-border-on: red;
}

.toggle-blue {
  --toggle-bg-on: blue;
  --toggle-border-on: blue;
}

Styling with Tailwind CSS

The Toggle component accepts a classes property which allows to override default class names. When using utility classes you don't need to import default.css. Here's a default styling for Tailwind CSS:

<Toggle v-model="value" :classes="{
  container: 'inline-block rounded-full outline-none focus:ring focus:ring-green-500 focus:ring-opacity-30',
  toggle: 'flex w-12 h-5 rounded-full relative cursor-pointer transition items-center box-content border-2 text-xs leading-none',
  toggleOn: 'bg-green-500 border-green-500 justify-start text-white',
  toggleOff: 'bg-gray-200 border-gray-200 justify-end text-gray-700',
  toggleOnDisabled: 'bg-gray-300 border-gray-300 justify-start text-gray-400 cursor-not-allowed',
  toggleOffDisabled: 'bg-gray-200 border-gray-200 justify-end text-gray-400 cursor-not-allowed',
  handle: 'inline-block bg-white w-5 h-5 top-0 rounded-full absolute transition-all',
  handleOn: 'left-full transform -translate-x-full',
  handleOff: 'left-0',
  handleOnDisabled: 'bg-gray-100 left-full transform -translate-x-full',
  handleOffDisabled: 'bg-gray-100 left-0',
  label: 'text-center w-8 border-box whitespace-nowrap select-none',
}" />

Certain classes has different states which are merged to the base class when the state is active. For example handle will be merged with handleOn when the toggle is on and not disabled resulting in the following classes: inline-block bg-white w-5 h-5 top-0 rounded-full absolute transition-all left-full transform -translate-x-full

The same is true for toggle.

In case you need to override the same type of utility you might use @neojp/tailwind-important-variant and use eg. bg-green-500!.

Accessibility

By default the on and off labels are being read by the screenreaders. If you provide the labelledby property that will be read instead of the labels. You might also add a describedby property to provide further description.

<div>
  <label id="toggle-label">Turn on notifications</label>
  <Toggle v-model="value" labelledby="toggle-label" describedby="toggle-description" />
</div>
<small id="toggle-description">Turn this on if you'd like to receive in-app notifications.</small>
