Props

Props of the native component are also available.

Name	Type	Default	Description
children*	element	-	Tooltip reference element.
arrow	bool	false	If `true`, adds an arrow to the tooltip.
color	'danger' \| 'neutral' \| 'primary' \| 'success' \| 'warning'	'neutral'	The color of the component. It supports those theme colors that make sense for this component. To learn how to add your own colors, check out Themed components—Extend colors.
component	elementType	-	The component used for the root node. Either a string to use a HTML element or a component.
describeChild	bool	false	Set to `true` if the `title` acts as an accessible description. By default the `title` acts as an accessible label for the child.
direction	'ltr' \| 'rtl'	'ltr'	Direction of the text.
disableFocusListener	bool	false	Do not respond to focus-visible events.
disableHoverListener	bool	false	Do not respond to hover events.
disableInteractive	bool	false	Makes a tooltip not interactive, i.e. it will close when the user hovers over the tooltip before the `leaveDelay` is expired.
disablePortal	bool	false	The `children` will be under the DOM hierarchy of the parent component.
disableTouchListener	bool	false	Do not respond to long press touch events.
enterDelay	number	100	The number of milliseconds to wait before showing the tooltip. This prop won't impact the enter touch delay (`enterTouchDelay`).
enterNextDelay	number	0	The number of milliseconds to wait before showing the tooltip when one was already recently opened.
enterTouchDelay	number	700	The number of milliseconds a user must touch the element before showing the tooltip.
followCursor	bool	false	If `true`, the tooltip follow the cursor over the wrapped element.
id	string	-	This prop is used to help implement the accessibility logic. If you don't provide this prop. It falls back to a randomly generated id.
keepMounted	bool	false	Always keep the children in the DOM. This prop can be useful in SEO situation or when you want to maximize the responsiveness of the Popper.
leaveDelay	number	0	The number of milliseconds to wait before hiding the tooltip. This prop won't impact the leave touch delay (`leaveTouchDelay`).
leaveTouchDelay	number	1500	The number of milliseconds after the user stops touching an element before hiding the tooltip.
modifiers	Array<{ data?: object, effect?: func, enabled?: bool, fn?: func, name?: any, options?: object, phase?: 'afterMain' \| 'afterRead' \| 'afterWrite' \| 'beforeMain' \| 'beforeRead' \| 'beforeWrite' \| 'main' \| 'read' \| 'write', requires?: Array<string>, requiresIfExists?: Array<string> }>	-	Popper.js is based on a "plugin-like" architecture, most of its features are fully encapsulated "modifiers". A modifier is a function that is called each time Popper.js needs to compute the position of the popper. For this reason, modifiers should be very performant to avoid bottlenecks. To learn how to create a modifier, read the modifiers documentation.
onClose	func	-	Callback fired when the component requests to be closed. Signature:`function(event: React.SyntheticEvent) => void` `event` The event source of the callback.
onOpen	func	-	Callback fired when the component requests to be open. Signature:`function(event: React.SyntheticEvent) => void` `event` The event source of the callback.
open	bool	-	If `true`, the component is shown.
placement	'bottom-end' \| 'bottom-start' \| 'bottom' \| 'left-end' \| 'left-start' \| 'left' \| 'right-end' \| 'right-start' \| 'right' \| 'top-end' \| 'top-start' \| 'top'	'bottom'	Tooltip placement.
size	'sm' \| 'md' \| 'lg'	'md'	The size of the component. To learn how to add custom sizes to the component, check out Themed components—Extend sizes.
slotProps	{ arrow?: func \| object, root?: func \| object }	{}	The props used for each slot inside.
slots	{ arrow?: elementType, root?: elementType }	{}	The components used for each slot inside. See Slots API below for more details.
sx	Array<func \| object \| bool> \| func \| object	-	The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
title	node	-	Tooltip title. Zero-length titles string, undefined, null and false are never displayed.
variant	'outlined' \| 'plain' \| 'soft' \| 'solid'	'solid'	The global variant to use. To learn how to add your own variants, check out Themed components—Extend variants.

The ref is forwarded to the root element.
