Hovercard

Indicates whether the element should be focusable even when it is disabled.

This is important when discoverability is a concern. For example:

Determines whether the content element should remain visible even when the open state is false. If this prop is set to true, the hidden prop and the display: none style will not be applied, unless explicitly set otherwise.

This prop is particularly useful when using third-party animation libraries such as Framer Motion or React Spring, where the element needs to be visible for exit animations to work.

The minimum padding between the arrow and the popover corner.

Automatically focuses the element upon mounting, similar to the native autoFocus prop. This addresses an issue where the element with the native autoFocus attribute might receive focus before React effects are executed.

The autoFocus prop can also be used with Focusable elements within a Dialog component, establishing the initial focus as the dialog opens.

Note: For this prop to work, the focusable prop must be set to true, if it's not set by default.

Determines whether an element outside of the dialog will be focused when the dialog is hidden if another element hasn't been focused in the action of hiding the dialog (for example, by clicking or tabbing into another tabbable element outside of the dialog).

By default, this is usually the disclosure element. The finalFocus prop can be used to define a different element to be focused.

Determines whether an element inside the dialog will receive focus when the dialog is shown. By default, this is usually the first tabbable element in the dialog or the dialog itself. The initialFocus prop can be used to set a different element to receive focus.

Determines whether there will be a backdrop behind the dialog. On modal dialogs, this is true by default. Besides a boolean, this prop can also be a React component or JSX element that will be rendered as the backdrop.

Note: If a custom component is used, it must accept ref and spread all props to its underlying DOM element, the same way a native element would.

Determines if the element is disabled. This sets the aria-disabled attribute accordingly, enabling support for all elements, including those that don't support the native disabled attribute.

This feature can be combined with the accessibleWhenDisabled prop to make disabled elements still accessible via keyboard.

Note: For this prop to work, the focusable prop must be set to true, if it's not set by default.

Determines if the pointer events outside of the popover and its anchor element should be disabled during hover intent, that is, when the mouse is moving toward the popover.

This is required as these external events may trigger focus on other elements and close the popover while the user is attempting to hover over it.

This can be either a boolean or a callback receiving the mouse event happening during hover intent. The callback should return a boolean.

Determines the element that will receive focus once the dialog is closed, provided that no other element has been focused while the dialog was being hidden (e.g., by clicking or tabbing into another tabbable element outside of the dialog).

• If autoFocusOnHide is set to false, this prop will have no effect.

• If left unset, the element that was focused before the dialog was opened will be focused again.

Whether the popover should fit the viewport. If this is set to true, the popover wrapper will have maxWidth and maxHeight set to the viewport size. This will be exposed to CSS as --popover-available-width and --popover-available-height.

Whether the popover has position: fixed or not.

Controls the behavior of the popover when it overflows the viewport:

• If a boolean, specifies whether the popover should flip to the opposite side when it overflows.

• If a string, indicates the preferred fallback placements when it overflows. The placements must be spaced-delimited, e.g. "top left".

Determines if Focusable features should be active on non-native focusable elements.

Note: This prop only turns off the additional features provided by the Focusable component. Non-native focusable elements will lose their focusability entirely. However, native focusable elements will retain their inherent focusability, but without added features such as improved autoFocus, accessibleWhenDisabled, onFocusVisible, etc.

Function that returns the anchor element's DOMRect. If this is explicitly passed, it will override the anchor getBoundingClientRect method.

When a dialog is open, the elements outside of it are disabled to prevent interaction if the dialog is modal. For non-modal dialogs, interacting with elements outside the dialog prompts it to close.

This function allows you to return an iterable collection of elements that will be considered as part of the dialog, thus excluding them from this behavior.

Note: The elements returned by this function must exist in the DOM when the dialog opens.

The distance between the popover and the anchor element.

Determines if the dialog will hide when the user presses the Escape key.

This prop can be either a boolean or a function that accepts an event as an argument and returns a boolean. The event object represents the keydown event that initiated the hide action, which could be either a native keyboard event or a React synthetic event.

Note: When placing Ariakit dialogs inside third-party dialogs, using event.stopPropagation() within this function will stop the event from reaching the third-party dialog, closing only the Ariakit dialog.

Determines whether the popover should hide when the mouse leaves the popover or the anchor element and there's no hover intent, meaning, the mouse isn't moving toward the popover.

This can be either a boolean or a callback receiving the mouse move event that initiated the behavior. The callback should return a boolean.

Note: This behavior won't be triggered when the popover or any of its descendants are in focus.

Determines if the dialog should hide when the user clicks or focuses on an element outside the dialog.

This prop can be either a boolean or a function that takes an event as an argument and returns a boolean. The event object represents the event that triggered the action, which could be a native event or a React synthetic event of various types.

Specifies the element that will receive focus when the dialog is first opened. It can be an HTMLElement or a React.RefObject with an HTMLElement.

If autoFocusOnShow is set to false, this prop will have no effect. If left unset, the dialog will attempt to determine the initial focus element in the following order:

1. 1

   A Focusable element with an autoFocus prop.

2. 2

   The first tabbable element inside the dialog.

3. 3

   The first focusable element inside the dialog.

4. 4

   The dialog element itself.

Determines whether the dialog is modal. Modal dialogs have distinct states and behaviors:

• The portal and preventBodyScroll props are set to true. They can still be manually set to false.

• When using the Heading or DialogHeading components within the dialog, their level will be reset so they start with h1.

• A visually hidden dismiss button will be rendered if the DialogDismiss component hasn't been used. This allows screen reader users to close the dialog.

• When the dialog is open, element tree outside it will be inert.

This is an event handler prop triggered when the dialog's close event is dispatched. The close event is similar to the native dialog close⁠ event. The only difference is that this event can be canceled with event.preventDefault(), which will prevent the dialog from hiding.

It's important to note that this event only fires when the dialog store's open state is set to false. If the controlled open prop value changes, or if the dialog's visibility is altered in any other way (such as unmounting the dialog without adjusting the open state), this event won't be triggered.

Custom event handler invoked when the element gains focus through keyboard interaction or a key press occurs while the element is in focus. This is the programmatic equivalent of the data-focus-visible attribute.

Note: For this prop to work, the focusable prop must be set to true, if it's not set by default.

Controls the open state of the dialog. This is similar to the open⁠ attribute on native dialog elements.

The minimum padding between the popover and the viewport edge. This will be exposed to CSS as --popover-overflow-padding.

Whether the popover can overlap the anchor element when it overflows.

Determines whether the element should be rendered as a React Portal.

An HTML element or a memoized callback function that returns an HTML element to be used as the portal element. By default, the portal element will be a div element appended to the document.body.

portalRef is similar to ref but is scoped to the portal node. It's useful when you need to be informed when the portal element is appended to the DOM or removed from the DOM.

When enabled, preserveTabOrder will keep the DOM element's tab order the same as the order in which the underlying Portal component was mounted in the React tree.

If the preserveTabOrderAnchor prop is provided, the tab order will be preserved relative to that element.

An anchor element for maintaining the tab order when preserveTabOrder prop is enabled. The tab order will be kept relative to this element.

By default, the tab order is kept relative to the original location in the React tree where the underlying Portal component was mounted.

Determines whether the body scrolling will be prevented when the dialog is shown. This is automatically set to true when the dialog is modal. You can disable this prop if you want to implement your own logic.

Allows the component to be rendered as a different HTML element or React component. The value can be a React element or a function that takes in the original component props and gives back a React element with the props merged.

Check out the Composition guide for more details.

Whether the popover should have the same width as the anchor element. This will be exposed to CSS as --popover-anchor-width.

The skidding of the popover along the anchor element. Can be set to negative values to make the popover shift to the opposite side.

Whether the popover should slide when it overflows.

Object returned by the useHovercardStore hook. If not provided, the closest HovercardProvider component's context will be used.

When set to true, the content element will be unmounted and removed from the DOM when it's hidden.

A callback that will be called when the popover needs to calculate its position. This will override the internal updatePosition function. The original updatePosition function will be passed as an argument, so it can be called inside the callback to apply the default behavior.

Props that will be passed to the popover wrapper element. This element will be used to position the popover.
