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"></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">

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'

⚠️ 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').
  • 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 😄), 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

Props:

  • open - Boolean that shows or hide the popover.
  • disabled - Boolean that disables the popover. If it was already open, it will be closed.
  • placement - (see above)
  • delay - (see above)
  • trigger - (see above)
  • offset - (see above)
  • container - (see above)
  • boundariesElement - (see above)
  • popperOptions - (see above)
  • popoverClass - Classes applied to the popover element. Use this to apply different themes to the popover.

  • popoverArrowClass - Class of the arrow element.
  • popoverInnerClass - Class of the inner content element.
  • autoHide - Hide the popover if clicked outside.
  • handleResize - Automatically update the popover position if its size changes.
  • open-group - If set, will close all the open popovers that have a different open-group value or unset.

You can change the default values in the Global options.

Events:

  • update:open(Boolean) - This allow you to use the .sync modifier on the open prop.
  • show
  • apply-show - Emitted after the show delay
  • hide
  • apply-hide - Emitted after the hide delay
  • dispose
  • auto-hide - Emitted when the popover is closed if clicked outside.
  • close-directive - Emitted when the popover is closed with the Close directive.
  • close-group - Emitted when the popover is closed because a popover of another open-group was shown.
  • resize - Emitted when the content size changes. You must set the handleResize prop to true.

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>
