Tooltip

A popup that displays information related to an element when the element receives keyboard focus or the mouse hovers over it.

Features

  • Provider to control display delay globally.
  • Opens when the trigger is focused or hovered.
  • Closes when the trigger is activated or when pressing escape.
  • Supports custom timings.

Anatomy

Import all parts and piece them together.

import { TooltipArrow, TooltipContent, TooltipPortal, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipProvider>
    <TooltipRoot>
      <TooltipTrigger />
      <TooltipPortal>
        <TooltipContent>
          <TooltipArrow />
        </TooltipContent>
      </TooltipPortal>
    </TooltipRoot>

API Reference

Provider

Wraps your app to provide global functionality to your tooltips.

PropDefaultType
delayDuration
700
number

The duration from when the pointer enters the trigger until the tooltip gets opened.

disableClosingTrigger
boolean

When true, clicking on trigger will not close the content.

disabled
boolean

When true, disable tooltip

disableHoverableContent
false
boolean

When true, trying to hover the content will result in the tooltip closing as the pointer leaves the trigger.

ignoreNonKeyboardFocus
false
boolean

Prevent the tooltip from opening if the focus did not come from the keyboard by matching against the :focus-visible selector. This is useful if you want to avoid opening it when switching browser tabs or closing a dialog.

skipDelayDuration
300
number

How much time a user has to enter another trigger without incurring a delay again.

Root

Contains all the parts of a tooltip.

PropDefaultType
defaultOpen
false
boolean

The open state of the tooltip when it is initially rendered. Use when you do not need to control its open state.

delayDuration
number

Override the duration given to the Provider to customise the open delay for a specific tooltip.

disableClosingTrigger
boolean

When true, clicking on trigger will not close the content.

disabled
boolean

When true, disable tooltip

disableHoverableContent
boolean

Prevents Tooltip.Content from remaining open when hovering. Disabling this has accessibility consequences. Inherits from Tooltip.Provider.

ignoreNonKeyboardFocus
boolean

Prevent the tooltip from opening if the focus did not come from the keyboard by matching against the :focus-visible selector. This is useful if you want to avoid opening it when switching browser tabs or closing a dialog.

open
boolean

The controlled open state of the tooltip.

EmitPayload
update:open
[value: boolean]

Event handler called when the open state of the tooltip changes.

Slots (default)Payload
open
boolean

Current open state

Trigger

The button that toggles the tooltip. By default, the TooltipContent will position itself against the trigger.

PropDefaultType
as
'button'
AsTag | Component

The element or component this component should render as. Can be overwrite by asChild

asChild
boolean

Change the default rendered element for the one passed as a child, merging their props and behavior.

Read our Composition guide for more details.

reference
ReferenceElement

The reference (or anchor) element that is being referred to for positioning.

If not provided will use the current component as anchor.

Data AttributeValue
[data-state]"closed" | "delayed-open" | "instant-open"

Portal

When used, portals the content part into the body.

PropDefaultType
disabled
boolean

Disable teleport and render the component inline

reference

forceMount
boolean

Used to force mounting when more control is needed. Useful when controlling animation with Vue animation libraries.

to
string | HTMLElement

Vue native teleport component prop :to

reference

Content

The component that pops out when the tooltip is open.

PropDefaultType
align
'start' | 'center' | 'end'

The preferred alignment against the trigger. May change when collisions occur.

alignOffset
number

An offset in pixels from the start or end alignment options.

ariaLabel
string

By default, screenreaders will announce the content inside the component. If this is not descriptive enough, or you have content that cannot be announced, use aria-label as a more descriptive label.

arrowPadding
number

The padding between the arrow and the edges of the content. If your content has border-radius, this will prevent it from overflowing the corners.

as
'div'
AsTag | Component

The element or component this component should render as. Can be overwrite by asChild

asChild
boolean

Change the default rendered element for the one passed as a child, merging their props and behavior.

Read our Composition guide for more details.

avoidCollisions
boolean

When true, overrides the side and align preferences to prevent collisions with boundary edges.

collisionBoundary
Element | (Element | null)[] | null

The element used as the collision boundary. By default this is the viewport, though you can provide additional element(s) to be included in this check.

collisionPadding
number | Partial<Record<'top' | 'right' | 'bottom' | 'left', number>>

The distance in pixels from the boundary edges where collision detection should occur. Accepts a number (same for all sides), or a partial padding object, for example: { top: 20, left: 20 }.

forceMount
boolean

Used to force mounting when more control is needed. Useful when controlling animation with Vue animation libraries.

hideWhenDetached
boolean

Whether to hide the content when the trigger becomes fully occluded.

side
'top'
'top' | 'right' | 'bottom' | 'left'

The preferred side of the trigger to render against when open. Will be reversed when collisions occur and avoidCollisions is enabled.

sideOffset
number

The distance in pixels from the trigger.

sticky
'partial' | 'always'

The sticky behavior on the align axis. partial will keep the content in the boundary as long as the trigger is at least partially in the boundary whilst "always" will keep the content in the boundary regardless.

EmitPayload
escapeKeyDown
[event: KeyboardEvent]

Event handler called when focus moves to the destructive action after opening. It can be prevented by calling event.preventDefault

pointerDownOutside
[event: Event]

Event handler called when a pointer event occurs outside the bounds of the component. It can be prevented by calling event.preventDefault.

Data AttributeValue

Examples

Configure globally

Use the Provider to control delayDuration and skipDelayDuration globally.

vue
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipProvider
    :delay-duration="800"
    :skip-delay-duration="500"
  >
    <TooltipRoot>
      <TooltipTrigger>…</TooltipTrigger>
      <TooltipContent>…</TooltipContent>
    </TooltipRoot>
    <TooltipRoot>
      <TooltipTrigger>…</TooltipTrigger>
      <TooltipContent>…</TooltipContent>
    </TooltipRoot>
  </TooltipProvider>
</template>

Show instantly

Use the delayDuration prop to control the time it takes for the tooltip to open.

vue
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipRoot :delay-duration="0">
    <TooltipTrigger>…</TooltipTrigger>
    <TooltipContent>…</TooltipContent>
  </TooltipRoot>
</template>

Displaying a tooltip from a disabled button

Since disabled buttons don't fire events, you need to:

  • Render the Trigger as span.
  • Ensure the button has no pointerEvents.
vue
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipRoot>
    <TooltipTrigger as-child>
      <span tabindex="0">
        <button
          disabled
          style="{ pointerEvents: 'none' }"
        >…</button>
      </span>
    </TooltipTrigger>
    <TooltipContent>…</TooltipContent>
  </TooltipRoot>
</template>

Constrain the content size

You may want to constrain the width of the content so that it matches the trigger width. You may also want to constrain its height to not exceed the viewport.

We expose several CSS custom properties such as --reka-tooltip-trigger-width and --reka-tooltip-content-available-height to support this. Use them to constrain the content dimensions.

vue
 <!-- index.vue -->
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipRoot>
    <TooltipTrigger>…</TooltipTrigger>
    <TooltipPortal>
      <TooltipContent
        class="TooltipContent"
        :side-offset="5"
      >

      </TooltipContent>
    </TooltipPortal>
  </TooltipRoot>
</template>
css
/* styles.css */
.TooltipContent {
  width: var(--reka-tooltip-trigger-width);
  max-height: var(--reka-tooltip-content-available-height);
}

Origin-aware animations

We expose a CSS custom property --reka-tooltip-content-transform-origin. Use it to animate the content from its computed origin based on side, sideOffset, align, alignOffset and any collisions.

vue
 <!-- index.vue -->
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipRoot>
    <TooltipTrigger>…</TooltipTrigger>
    <TooltipContent class="TooltipContent">

    </TooltipContent>
  </TooltipRoot>
</template>
css
/* styles.css */
.TooltipContent {
  transform-origin: var(--reka-tooltip-content-transform-origin);
  animation: scaleIn 0.5s ease-out;
}

@keyframes scaleIn {
  from {
    opacity: 0;
    transform: scale(0);
  }
  to {
    opacity: 1;
    transform: scale(1);
  }
}

Collision-aware animations

We expose data-side and data-align attributes. Their values will change at runtime to reflect collisions. Use them to create collision and direction-aware animations.

vue
 <!-- index.vue -->
<script setup>
import { TooltipContent, TooltipProvider, TooltipRoot, TooltipTrigger } from 'reka-ui'
</script>

<template>
  <TooltipRoot>
    <TooltipTrigger>…</TooltipTrigger>
    <TooltipContent class="TooltipContent">

    </TooltipContent>
  </TooltipRoot>
</template>
css
/* styles.css */
.TooltipContent {
  animation-duration: 0.6s;
  animation-timing-function: cubic-bezier(0.16, 1, 0.3, 1);
}
.TooltipContent[data-side="top"] {
  animation-name: slideUp;
}
.TooltipContent[data-side="bottom"] {
  animation-name: slideDown;
}

@keyframes slideDown {
  from {
    opacity: 0;
    transform: translateY(-10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

@keyframes slideUp {
  from {
    opacity: 0;
    transform: translateY(10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

Custom APIs

Create your own API by abstracting the primitive parts into your own component.

Abstract parts and introduce a content prop

This example abstracts all of the Tooltip parts and introduces a new content prop.

Usage

vue
<script setup lang="ts">
import { Tooltip } from './your-tooltip'
</script>

<template>
  <Tooltip content="Tooltip content">
    <button>Tooltip trigger</button>
  </Tooltip>
</template>

Implementation

Use the asChild prop to convert the trigger part into a slottable area. It will replace the trigger with the child that gets passed to it.

vue
<!-- your-tooltip.vue  -->
<script setup lang="ts">
import { TooltipArrow, TooltipContent, TooltipRoot, type TooltipRootEmits, type TooltipRootProps, TooltipTrigger, useForwardPropsEmits } from 'reka-ui'

const props = defineProps<TooltipRootProps & { content?: string }>()
const emits = defineEmits<TooltipRootEmits>()

const forward = useForwardPropsEmits(props, emits)
</script>

<template>
  <TooltipRoot v-bind="forward">
    <TooltipTrigger as-child>
      <slot />
    </TooltipTrigger>
    <TooltipContent
      side="top"
      align="center"
    >
      {{ content }}
      <TooltipArrow
        :width="11"
        :height="5"
      />
    </TooltipContent>
  </TooltipRoot>
</template>
