# Tooltip

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

## Import

```
Copyts
import { Tooltip } from "@kobalte/core/tooltip";
// or
import { Root, Trigger, ... } from "@kobalte/core/tooltip";
// or (deprecated)
import { Tooltip } from "@kobalte/core";
```

```
Copyts
import { Tooltip } from "@kobalte/core/tooltip";
// or
import { Root, Trigger, ... } from "@kobalte/core/tooltip";
// or (deprecated)
import { Tooltip } from "@kobalte/core";
```

## Features

- Exposed as a tooltip to assistive technology via ARIA.
- Opens when the trigger is focused or hovered.
- Closes when the trigger is activated or when pressing escape.
- Only one tooltip shows at a time.
- Labeling support for screen readers via `aria-describedby`.
- Custom show and hide delay support.
- Matches native tooltip behavior with delay on hover of first tooltip and no delay on subsequent tooltips.

## Anatomy

The tooltip consists of:

- **Tooltip:** The root container for a tooltip.
- **Tooltip.Trigger:** The button that toggles the tooltip.
- **Tooltip.Portal:** Portals its children into the `body` when the tooltip is open.
- **Tooltip.Content:** Contains the content to be rendered when the tooltip is open.
- **Tooltip.Arrow:** An optional arrow element to render alongside the tooltip.

```
Copytsx
<Tooltip>
	<Tooltip.Trigger />
	<Tooltip.Portal>
		<Tooltip.Content>
			<Tooltip.Arrow />
		</Tooltip.Content>
	</Tooltip.Portal>
</Tooltip>
```

```
Copytsx
<Tooltip>
	<Tooltip.Trigger />
	<Tooltip.Portal>
		<Tooltip.Content>
			<Tooltip.Arrow />
		</Tooltip.Content>
	</Tooltip.Portal>
</Tooltip>
```

## Example

Trigger

index.tsxstyle.css

```
Copytsx
import { Tooltip } from "@kobalte/core/tooltip";
import "./style.css";

function App() {
  return (
    <Tooltip>
      <Tooltip.Trigger class="tooltip__trigger">Trigger</Tooltip.Trigger>
      <Tooltip.Portal>
        <Tooltip.Content class="tooltip__content">
          <Tooltip.Arrow />
          <p>Tooltip content</p>
        </Tooltip.Content>
      </Tooltip.Portal>
    </Tooltip>
  );
}
```

```
Copytsx
import { Tooltip } from "@kobalte/core/tooltip";
import "./style.css";

function App() {
  return (
    <Tooltip>
      <Tooltip.Trigger class="tooltip__trigger">Trigger</Tooltip.Trigger>
      <Tooltip.Portal>
        <Tooltip.Content class="tooltip__content">
          <Tooltip.Arrow />
          <p>Tooltip content</p>
        </Tooltip.Content>
      </Tooltip.Portal>
    </Tooltip>
  );
}
```

## Usage

### Default open

An initial, uncontrolled open value can be provided using the `defaultOpen` prop.

```
Copytsx
<Tooltip defaultOpen>...</Tooltip>
```

```
Copytsx
<Tooltip defaultOpen>...</Tooltip>
```

### Controlled open

The `open` prop can be used to make the open state controlled. The `onOpenChange` event is fired when the user presses the trigger, close button or interact outside, and receives the new value.

Tooltip is not showing.

Trigger

```
Copytsx
import { createSignal } from "solid-js";

function ControlledExample() {
	const [open, setOpen] = createSignal(false);

	return (
		<>
			<p>Tooltip is {open() ? "showing" : "not showing"}.</p>
			<Tooltip open={open()} onOpenChange={setOpen}>
				<Tooltip.Trigger>Trigger</Tooltip.Trigger>
				<Tooltip.Portal>
					<Tooltip.Content>
						<Tooltip.Arrow />
						<p>Tooltip content</p>
					</Tooltip.Content>
				</Tooltip.Portal>
			</Tooltip>
		</>
	);
}
```

```
Copytsx
import { createSignal } from "solid-js";

function ControlledExample() {
	const [open, setOpen] = createSignal(false);

	return (
		<>
			<p>Tooltip is {open() ? "showing" : "not showing"}.</p>
			<Tooltip open={open()} onOpenChange={setOpen}>
				<Tooltip.Trigger>Trigger</Tooltip.Trigger>
				<Tooltip.Portal>
					<Tooltip.Content>
						<Tooltip.Arrow />
						<p>Tooltip content</p>
					</Tooltip.Content>
				</Tooltip.Portal>
			</Tooltip>
		</>
	);
}
```

### Origin-aware animations

We expose a CSS custom property `--kb-tooltip-content-transform-origin` which can be used to animate the content from its computed origin.

```
Copycss
/* style.css */
.tooltip__content {
	transform-origin: var(--kb-tooltip-content-transform-origin);
	animation: contentHide 250ms ease-in forwards;
}

.tooltip__content[data-expanded] {
	animation: contentShow 250ms ease-out;
}

@keyframes contentShow {
	from {
		opacity: 0;
		transform: scale(0.96);
	}
	to {
		opacity: 1;
		transform: scale(1);
	}
}

@keyframes contentHide {
	from {
		opacity: 1;
		transform: scale(1);
	}
	to {
		opacity: 0;
		transform: scale(0.96);
	}
}
```

```
Copycss
/* style.css */
.tooltip__content {
	transform-origin: var(--kb-tooltip-content-transform-origin);
	animation: contentHide 250ms ease-in forwards;
}

.tooltip__content[data-expanded] {
	animation: contentShow 250ms ease-out;
}

@keyframes contentShow {
	from {
		opacity: 0;
		transform: scale(0.96);
	}
	to {
		opacity: 1;
		transform: scale(1);
	}
}

@keyframes contentHide {
	from {
		opacity: 1;
		transform: scale(1);
	}
	to {
		opacity: 0;
		transform: scale(0.96);
	}
}
```

## API Reference

### Tooltip

`Tooltip` is equivalent to the `Root` import from `@kobalte/core/tooltip` (and deprecated `Tooltip.Root`).

| Prop | Description |
| --- | --- |
| open | `boolean`<br> The controlled open state of the tooltip. |
| defaultOpen | `boolean`<br> The default open state when initially rendered. Useful when you do not need to control the open state. |
| onOpenChange | `(open: boolean) => void`<br> Event handler called when the open state of the tooltip changes. |
| triggerOnFocusOnly | `boolean`<br> Whether to open the tooltip only when the trigger is focused. By default, opens for both focus and hover. |
| openDelay | `number`<br> The duration from when the mouse enters the trigger until the tooltip opens. |
| skipDelayDuration | `number`<br> The duration from when the mouse leaves the trigger or content and moves to another tooltip trigger or content without incurring another openDelay |
| closeDelay | `number`<br> The duration from when the mouse leaves the trigger or content until the tooltip closes. |
| ignoreSafeArea | `boolean`<br> Whether to close the tooltip even if the user cursor is inside the safe area between the trigger and tooltip. |
| id | `string`<br> A unique identifier for the component. The id is used to generate id attributes for nested components. If no id prop is provided, a generated id will be used. |
| forceMount | `boolean`<br> Used to force mounting the tooltip (portal and content) when more control is needed. Useful when controlling animation with SolidJS animation libraries. |

`Tooltip` also accepts the following props to customize the placement of the `Tooltip.Content`.

| Prop | Description |
| --- | --- |
| getAnchorRect | `(anchor?: HTMLElement) => AnchorRect  | undefined`<br> Function that returns the anchor element's DOMRect. |
| placement | `Placement`<br> The placement of the tooltip. |
| gutter | `number`<br> The distance between the tooltip and the trigger/anchor element. By default, it's 0 plus half of the arrow offset, if it exists. |
| shift | `number`<br> The skidding of the tooltip along the anchor element. |
| flip | `boolean | string`<br> Controls the behavior of the tooltip when it overflows the viewport:<br> \- If a `boolean`, specifies whether the tooltip should flip to the opposite side when it overflows.<br> \- If a `string`, indicates the preferred fallback placements when it overflows.<br>The placements must be spaced-delimited, e.g. "top left". |
| slide | `boolean`<br> Whether the tooltip should slide when it overflows. |
| overlap | `boolean`<br> Whether the tooltip can overlap the anchor element when it overflows. |
| sameWidth | `boolean`<br> Whether the tooltip should have the same width as the anchor element. This will be exposed to CSS as `--kb-popper-anchor-width`. |
| fitViewport | `boolean`<br> Whether the tooltip should fit the viewport. If this is set to true, the tooltip content will have `maxWidth` and `maxHeight` set to the viewport size. This will be exposed to CSS as `--kb-popper-available-width` and `--kb-popper-available-height`. |
| hideWhenDetached | `boolean`<br> Whether to hide the tooltip when the anchor element becomes occluded. |
| detachedPadding | `number`<br> The minimum padding in order to consider the anchor element occluded. |
| arrowPadding | `number`<br> The minimum padding between the arrow and the tooltip corner. |
| overflowPadding | `number`<br> The minimum padding between the tooltip and the viewport edge. This will be exposed to CSS as `--kb-popper-overflow-padding`. |

### Tooltip.Trigger

| Data attribute | Description |
| --- | --- |
| data-expanded | Present when the tooltip is open. |
| data-closed | Present when the tooltip is close. |

`Tooltip.Content` and `Tooltip.Arrow` share the same data-attributes.

### Tooltip.Content

The popper positioner will copy the same `z-index` as the `Tooltip.Content`.

| Prop | Description |
| --- | --- |
| onEscapeKeyDown | `(event: KeyboardEvent) => void`<br> Event handler called when the escape key is down. It can be prevented by calling `event.preventDefault`. |
| onPointerDownOutside | `(event: PointerDownOutsideEvent) => void`<br> Event handler called when a pointer event occurs outside the bounds of the component. It can be prevented by calling `event.preventDefault`. |

### Tooltip.Arrow

| Prop | Description |
