Features

Built-in state machine to control display delay.
Opens when the trigger is focused or hovered.
Closes when the trigger is activated or when pressing escape.
Supports custom timings.

Installation

Install the component from your command line.

npm install @radix-ui/react-tooltip

Anatomy

Import all parts and piece them together.

import * as Tooltip from '@radix-ui/react-tooltip';

export default () => (
  <Tooltip.Root>
    <Tooltip.Trigger />
    <Tooltip.Content>
      <Tooltip.Arrow />
    </Tooltip.Content>
  </Tooltip.Root>
);

API Reference

Root

Contains all the parts of a tooltip.

Prop	Type	Default
`defaultOpen`	`boolean`	No default value
`open`	`boolean`	No default value
`onOpenChange`	`function`	No default value
`delayDuration`	`number`	`700`
`skipDelayDuration`	`number`	`300`

Trigger

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

Prop	Type	Default
`as`	`enum`	`button`

Content

The component that pops out when the tooltip is open.

Prop	Type	Default
`as`	`enum`	`div`
`aria-label`	`string`	No default value
`portalled`	`boolean`	`true`
`side`	`enum`	`"bottom"`
`sideOffset`	`number`	`0`
`align`	`enum`	`"center"`
`alignOffset`	`number`	`0`
`avoidCollisions`	`boolean`	`true`
`collisionTolerance`	`boolean`	`0`

Arrow

An optional arrow element to render alongside the tooltip. This can be used to help visually link the trigger with the Tooltip.Content. Must be rendered inside Tooltip.Content.

Prop	Type	Default
`as`	`enum`	`svg`
`width`	`number`	`10`
`height`	`number`	`5`
`offset`	`number`	No default value

Examples

Show instantly

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

import * as Tooltip from '@radix-ui/react-tooltip';

export default () => (
  <Tooltip.Root delayDuration={0}>
    <Tooltip.Trigger>…</Tooltip.Trigger>
    <Tooltip.Content>…</Tooltip.Content>
  </Tooltip.Root>
);

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

Render the Trigger as span.
Ensure the button has no pointerEvents.

import * as Tooltip from '@radix-ui/react-tooltip';

export default () => (
  <Tooltip.Root>
    <Tooltip.Trigger as="span">
      <button disabled style={{ pointerEvents: 'none' }}>
        …
      </button>
    </Tooltip.Trigger>
    <Tooltip.Content>…</Tooltip.Content>
  </Tooltip.Root>
);

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

import { styled, keyframes } from '@stitches/react';
import * as Tooltip from '@radix-ui/react-tooltip';

const scaleIn = keyframes({
  '0%': { opacity: 0, transform: 'scale(0)' },
  '100%': { opacity: 1, transform: 'scale(1)' },
});

const TooltipContent = styled(Tooltip.Content, {
  transformOrigin: 'var(--radix-tooltip-content-transform-origin)',
  animation: `${scaleIn} 0.5s ease-out`,
});

export default () => (
  <Tooltip.Root>
    <Tooltip.Trigger>…</Tooltip.Trigger>
    <TooltipContent>…</TooltipContent>
  </Tooltip.Root>
);

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.

import { styled, keyframes } from '@stitches/react';
import * as Tooltip from '@radix-ui/react-tooltip';

const slideDown = keyframes({
  '0%': { opacity: 0, transform: 'translateY(-10px)' },
  '100%': { opacity: 1, transform: 'translateY(0)' },
});

const slideUp = keyframes({
  '0%': { opacity: 0, transform: 'translateY(10px)' },
  '100%': { opacity: 1, transform: 'translateY(0)' },
});

const TooltipContent = styled(Tooltip.Content, {
  '&[data-side="top"]': { animationName: slideUp },
  '&[data-side="bottom"]': { animationName: slideDown },
  animationDuration: '0.6s',
  animationTimingFunction: 'cubic-bezier(0.16, 1, 0.3, 1)',
});

export default () => (
  <Tooltip.Root>
    <Tooltip.Trigger>…</Tooltip.Trigger>
    <TooltipContent>…</TooltipContent>
  </Tooltip.Root>
);

Keyboard Interactions

Key	Description
`Tab`	Opens/closes the tooltip without delay.
`Space`	If open, closes the tooltip without delay.
`Enter`	If open, closes the tooltip without delay.
`Escape`	If open, closes the tooltip without delay.

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

import { Tooltip } from './your-tooltip';

export default () => (
  <Tooltip content="Tooltip content">
    <button>Tooltip trigger</button>
  </Tooltip>
);

Implementation

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

// your-tooltip.jsx
import React from 'react';
import * as TooltipPrimitive from '@radix-ui/react-tooltip';
import { Slot } from '@radix-ui/react-slot';

export function Tooltip({
  children,
  content,
  open,
  defaultOpen,
  onOpenChange,
  ...props
}) {
  return (
    <TooltipPrimitive.Root
      open={open}
      defaultOpen={defaultOpen}
      onOpenChange={onOpenChange}
    >
      <TooltipPrimitive.Trigger as={Slot}>{children}</TooltipPrimitive.Trigger>
      <TooltipPrimitive.Content side="top" align="center" {...props}>
        {content}
        <TooltipPrimitive.Arrow offset={5} width={11} height={5} />
      </TooltipPrimitive.Content>
    </TooltipPrimitive.Root>
  );
}
