Getting started

This package offers two different usages: directive or component. You can use them to create tooltips, popovers or all kinds of dropdowns.

  1. Install the plugin:
npm install --save v-tooltip
  1. Add the plugin into your app:
import Vue from 'vue'
import VTooltip from 'v-tooltip'

Vue.use(VTooltip)

More info on installation

  1. Add some style to your liking.

  2. Use the v-tooltip directive:

<button v-tooltip="'You have ' + count + ' new messages.'">

More info on the directive

  1. Use the v-popover component:
<v-popover>
  <!-- This will be the popover target (for the events and position) -->
  <button>Click me</button>
  <!-- This will be the content of the popover -->
  <MyAwesomeComponent slot="popover"/>
</v-popover>

More info on the component


Installation

Npm

npm install --save v-tooltip

Install the plugin into Vue:

import Vue from 'vue'
import VTooltip from 'v-tooltip'

Vue.use(VTooltip)

Or use the directives and components directly:

import Vue from 'vue'
import { VTooltip, VPopover, VClosePopover } from 'v-tooltip'

Vue.directive('tooltip', VTooltip)
Vue.directive('close-popover', VClosePopover)
Vue.component('v-popover', VPopover)

Browser

Include v-tooltip in the page.

<script src="https://unpkg.com/v-tooltip@^2.0.0"></script>

If Vue is detected in the Page, the plugin is installed automatically.

Manually install the plugin into Vue:

Vue.use(VTooltip)

Or use the directives and components directly:

Vue.directive('tooltip', VTooltip.VTooltip)
Vue.directive('close-popover', VTooltip.VClosePopover)
Vue.component('v-popover', VTooltip.VPopover)

Usage

Directive

In the template, use the v-tooltip directive:

<button v-tooltip="'You have ' + count + ' new messages.'">

Of course, you can use a reactive property:

<button v-tooltip="tooltipContent">

⚠️ HTML is enabled in the tooltip by default. If you plan on using content coming from the users, please disable HTML parsing with the html global option to prevent XSS attacks:

import VTooltip from 'v-tooltip'
Vue.use(VTooltip, {
  defaultHtml: false,
})

Or directly on package:

import VTooltip from 'v-tooltip'
VTooltip.options.defaultHtml = false

You can then specify html: true on each tooltip you want to render HTML in. See below for more info on the tooltip options.

You can specify the tooltip position as a modifier:

<button v-tooltip.bottom-start="'You have ' + count + ' new messages.'">

The available positions are:

  • 'auto'
  • 'auto-start'
  • 'auto-end'
  • 'top'
  • 'top-start'
  • 'top-end'
  • 'right'
  • 'right-start'
  • 'right-end'
  • 'bottom'
  • 'bottom-start'
  • 'bottom-end'
  • 'left'
  • 'left-start'
  • 'left-end'

:warning: You need to add style to the tooltips: examples.

Object notation

You can use an object instead of a simple string:

<button v-tooltip="{ content: 'You have ' + count + ' new messages.' }">

Dynamic CSS classes

You can set the tooltip css classes dynamically with the object notation:

<button v-tooltip="{ content: 'You have ' + count + ' new messages.', classes: ['a', 'b'] }">

This will replace the default CSS classe with 'a b' on the tooltip element.

You can also use the standard class notation:

<button v-tooltip="{ content: 'You have ' + count + ' new messages.', classes: 'a b' }">

Or a reactive property:

<button v-tooltip="{ content: 'You have ' + count + ' new messages.', classes: tooltipClasses }">

Other options

<button v-tooltip="options">
  • content - HTML text to be displayed in the tooltip. Can also be a function that returns the content or a Promise.
  • classes - (see above)
  • targetClasses - CSS classes added to the target element of the tooltip.
  • html - Boolean: allow HTML tooltip content.
  • delay - Show/Hide delay, or object: { show: 500, hide: 100 } (ms).
  • placement - (see above)
  • trigger - Events triggering the tooltip separated with spaces: 'hover', 'click', 'focus' or 'manual' ('manual' can't be combined with any other event).
  • show - Boolean to manually open or hide the tooltip.
  • offset - Offset of the position (px).
  • container - Selector: Container where the tooltip will be appended (e.g. 'body'). Set it to false to append popover on target parent node.
  • boundariesElement - DOM element for the tooltip boundaries.
  • template - HTML template of the tooltip.
  • arrowSelector - CSS selector to get the arrow element in the tooltip template.
  • innerSelector - CSS selector to get the inner content element in the tooltip template.
  • autoHide - Boolean: automatically close the tooltip on mouseover.
  • hideOnTargetClick - Boolean: automatically close the tooltip on target click.
  • loadingClass - CSS classes added to the tooltip when content is loading.
  • loadingContent - Same as content, used when the actual tooltip content is loading.
  • popperOptions - Other Popper.js options.

You can change the default values in the Global options.

Async content example

The content option accepts a promise:

<button
  v-tooltip="{
    content: asyncMethod(),
    loadingContent: 'Please wait...',
    loadingClass: 'content-is-loading',
  }"
>Hover me!</button>

Manual trigger example

Use the trigger and show options:

<button
  v-tooltip="{
    content: 'Tooltip content here',
    show: isOpen,
    trigger: 'manual',
  }"
>A button</button>

Tooltip auto-hiding

By default, if trigger contains 'hover', the tooltip is automatically hidden on hover or click. To disable this, set the autoHide option to false:

VTooltip.options.autoHide = false

Disabling tooltips

On mobile, you can disable the tooltips with the VTooltip.enabled property:

VTooltip.enabled = window.innerWidth > 768

Component

If you need to display components inside the tooltip (or popover/dropdown, technically it's the same :smile:), use the v-popover component:

<v-popover
  offset="16"
>
  <!-- This will be the popover target (for the events and position) -->
  <button class="tooltip-target b3">Click me</button>

  <!-- This will be the content of the popover -->
  <template slot="popover">
    <input class="tooltip-content" v-model="msg" placeholder="Tooltip content" />
    <p>
      {{ msg }}
    </p>

    <!-- You can put other components too -->
    <ExampleComponent char="=" />
  </template>
</v-popover>

By default, the popover will have the tooltip and popover classes, so you can easily override the style:

.tooltip {
  // ...

  &.popover {
    $color: #f9f9f9;

    .popover-inner {
      background: $color;
      color: black;
      padding: 24px;
      border-radius: 5px;
      box-shadow: 0 5px 30px rgba(black, .1);
    }

    .popover-arrow {
      border-color: $color;
    }
  }
}

⚠️ Set the arrow element z-index CSS property:

.tooltip-arrow {
  z-index: 1;
}

Popover Component Reference

  • open - Boolean that shows or hide the popover.
  • disabled - Boolean that disables the popover. If it was already open, it will be closed.

  • offset - (see above)
  • container - (see above)

Disable popover

<v-popover :disabled="isDisabled"></v-popover>
data () {
  return {
    isDisabled: true,
  }
}

Close directive

Use the v-close-popover directive on an element inside the popover to close it when the element is clicked (or touched on mobile):

<v-popover>
  <button>Click me</button>

  <template slot="popover">
    <a v-close-popover>Close</a>
  </template>
</v-popover>

You can also set it to true or false to enable or disable the directive (enabled by default):

<a v-close-popover="false">Close</a>
<a v-close-popover="true">Close</a>

You can also use a property:

<a v-close-popover="myBooleanProp">Close</a>
data () {
  return {
    myBooleanProp: true,
  }
}

Close all the popovers in the page with the all modifier:

<a v-close-popover.all>Close All</a>
