Tooltip

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

import React from 'react';
import * as Tooltip from '@radix-ui/react-tooltip';
import { PlusIcon } from '@radix-ui/react-icons';
import './styles.css';

const TooltipDemo = () => {
  return (
    <Tooltip.Provider>
      <Tooltip.Root>
        <Tooltip.Trigger asChild>
          <button className="IconButton">
            <PlusIcon />
          </button>
        </Tooltip.Trigger>
        <Tooltip.Portal>
          <Tooltip.Content className="TooltipContent" sideOffset={5}>
            Add to library
            <Tooltip.Arrow className="TooltipArrow" />
          </Tooltip.Content>
        </Tooltip.Portal>
      </Tooltip.Root>
    </Tooltip.Provider>
  );
};

export default TooltipDemo;

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.

Installation

Install the component from your command line.

npm install @radix-ui/react-tooltip

Anatomy

    <Tooltip.Root>
      <Tooltip.Trigger />
      <Tooltip.Portal>
        <Tooltip.Content>
          <Tooltip.Arrow />
        </Tooltip.Content>
      </Tooltip.Portal>

CSS Variable	Description
`--radix-tooltip-content-transform-origin`	The `transform-origin` computed from the content and arrow positions/offsets
`--radix-tooltip-content-available-width`	The remaining width between the trigger and the boundary edge

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.

Examples

Configure globally

Use the Provider to control delayDuration and skipDelayDuration globally.

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

export default () => (
  <Tooltip.Provider delayDuration={800} skipDelayDuration={500}>
    <Tooltip.Root>
      <Tooltip.Trigger>…</Tooltip.Trigger>
      <Tooltip.Content>…</Tooltip.Content>
    </Tooltip.Root>
    <Tooltip.Root>
      <Tooltip.Trigger>…</Tooltip.Trigger>
      <Tooltip.Content>…</Tooltip.Content>
    </Tooltip.Root>
  </Tooltip.Provider>
);

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 asChild>
      <span tabIndex={0}>
        <button disabled style={{ pointerEvents: 'none' }}>
          …
        </button>
      </span>
    </Tooltip.Trigger>
    <Tooltip.Content>…</Tooltip.Content>
  </Tooltip.Root>
);

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 --radix-tooltip-trigger-width and --radix-tooltip-content-available-height to support this. Use them to constrain the content dimensions.

// index.jsx
import * as Tooltip from '@radix-ui/react-tooltip';
import './styles.css';

export default () => (
  <Tooltip.Root>
    <Tooltip.Trigger>…</Tooltip.Trigger>
    <Tooltip.Portal>
      <Tooltip.Content className="TooltipContent" sideOffset={5}>
        …
      </Tooltip.Content>
    </Tooltip.Portal>
  </Tooltip.Root>
);

/* styles.css */
.TooltipContent {
  width: var(--radix-tooltip-trigger-width);
  max-height: var(--radix-tooltip-content-available-height);
}

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.

// index.jsx
import * as Tooltip from '@radix-ui/react-tooltip';
import './styles.css';

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

/* styles.css */
.TooltipContent {
  transform-origin: var(--radix-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.

// index.jsx
import * as Tooltip from '@radix-ui/react-tooltip';
import './styles.css';

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

/* 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);
  }
}

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 asChild prop 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';

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