API#

usePopover(
  (props: AriaPopoverProps,
  , state: OverlayTriggerState
)): PopoverAria

Features#

There is no built in way to create popovers in HTML. usePopover, helps achieve accessible popovers that can be styled as needed.

Accessible – The trigger and popover are automatically associated semantically via ARIA. Content outside the popover is hidden from assistive technologies while it is open. The popover closes when interacting outside, or pressing the Escape key.
Focus management – Focus is moved into the popover on mount, and restored to the trigger element on unmount.
Positioning – The popover is positioned relative to the trigger element, and automatically flips and adjusts to avoid overlapping with the edge of the browser window. Scrolling is prevented outside the popover to avoid unintentionally repositioning or closing it.

Note: usePopover only handles the overlay itself. It should be combined with useDialog to create fully accessible popovers. Other overlays such as menus may also be placed in a popover.

Anatomy#

A popover consists of a trigger element (e.g. button) and an overlay, which is positioned relative to the trigger. The overlay may contain a dialog, or another element such as a menu or listbox when used within a component such as a select or combobox.

usePopover returns props that you should spread onto the appropriate elements, as well as the computed placement of the popover relative to the trigger:

Name	Type	Description
`popoverProps`	`DOMAttributes`	Props for the popover element.
`arrowProps`	`DOMAttributes`	Props for the popover tip arrow if any.
`underlayProps`	`DOMAttributes`	Props to apply to the underlay element, if any.
`placement`	`PlacementAxis`	Placement of the popover with respect to the trigger.

State is managed by the useOverlayTriggerState hook in @react-stately/overlays. The state object should be passed as an argument to usePopover.

Example#

This example shows how to build a typical popover overlay that is positioned relative to a trigger button. The content of the popover is a dialog, built with useDialog. The Dialog component used in this example can also be reused within a modal or other types of overlays. The implementation is available below.

The Popover component uses an <Overlay> to render its contents in a React Portal at the end of the document body, which ensures it is not clipped by other elements. It also acts as a focus scope, containing focus within the popover and restoring it to the trigger when it unmounts. usePopover handles positioning the popover relative to the trigger element, and closing it when the user interacts outside or presses the Escape key.

usePopover also hides content outside the popover from screen readers, which is important since the surrounding content won't be in context of the original trigger due to the portal. To allow screen reader users to dismiss the popover without a keyboard (e.g. on mobile), visually hidden <DismissButton> elements are added at the start and end of the popover. An underlay is also used to prevent scrolling and interacting with elements outside the popover with a pointer, to avoid unintentially repositioning or closing it.

import {DismissButton, Overlay, usePopover} from 'react-aria';
import type {AriaPopoverProps} from 'react-aria';
import type {OverlayTriggerState} from 'react-stately';

interface PopoverProps extends Omit<AriaPopoverProps, 'popoverRef'> {

import {

} from 'react-aria';
import type {AriaPopoverProps} from 'react-aria';
import type {OverlayTriggerState} from 'react-stately';

interface PopoverProps

    Omit<
      AriaPopoverProps,

      </div>

The above Popover component can be used as part of many different patterns, such as ComboBox, Select, and DatePicker. To use it standalone, we need a trigger element. The below PopoverTrigger component uses the useOverlayTrigger hook to trigger the popover when a button is pressed. This hook also ensures that the button and popover are semantically connected via ARIA.

import {useOverlayTrigger} from 'react-aria';
import {useOverlayTriggerState} from 'react-stately';

// Reuse the Button from your component library. See below for details.
import {Button} from 'your-component-library';

function PopoverTrigger({ label, children, ...props }) {
  let ref = React.useRef(null);
  let state = useOverlayTriggerState(props);
  let { triggerProps, overlayProps } = useOverlayTrigger(
    { type: 'dialog' },
    state,
    ref
  );

  return (
    <>
      <Button {...triggerProps} buttonRef={ref}>{label}</Button>
      {state.isOpen &&
        (
          <Popover {...props} triggerRef={ref} state={state}>
            {React.cloneElement(children, overlayProps)}
          </Popover>
        )}
    </>
  );
}

import {useOverlayTrigger} from 'react-aria';
import {useOverlayTriggerState} from 'react-stately';

// Reuse the Button from your component library. See below for details.
import {Button} from 'your-component-library';

function PopoverTrigger({ label, children, ...props }) {
  let ref = React.useRef(null);
  let state = useOverlayTriggerState(props);
  let { triggerProps, overlayProps } = useOverlayTrigger(
    { type: 'dialog' },
    state,
    ref
  );

  return (
    <>
      <Button {...triggerProps} buttonRef={ref}>
        {label}
      </Button>
      {state.isOpen &&
        (
          <Popover
            {...props}
            triggerRef={ref}
            state={state}
          >
            {React.cloneElement(children, overlayProps)}
          </Popover>
        )}
    </>
  );
}

import {useOverlayTrigger} from 'react-aria';
import {useOverlayTriggerState} from 'react-stately';

// Reuse the Button from your component library. See below for details.
import {Button} from 'your-component-library';

function PopoverTrigger(
  {
    label,
    children,
    ...props
  }
) {
  let ref = React.useRef(
    null
  );
  let state =
    useOverlayTriggerState(
      props
    );
  let {
    triggerProps,
    overlayProps
  } = useOverlayTrigger(
    { type: 'dialog' },
    state,
    ref
  );

  return (
    <>
      <Button
        {...triggerProps}
        buttonRef={ref}
      >
        {label}
      </Button>
      {state.isOpen &&
        (
          <Popover
            {...props}
            triggerRef={ref}
            state={state}
          >
            {React
              .cloneElement(
                children,
                overlayProps
              )}
          </Popover>
        )}
    </>
  );
}

Now, we can render an example popover containing a dialog.

// Reuse the Dialog from your component library. See below for details.
import {Dialog} from 'your-component-library';

<PopoverTrigger label="Open Popover">
  <Dialog title="Popover title">
    This is the content of the popover.
  </Dialog>
</PopoverTrigger>

// Reuse the Dialog from your component library. See below for details.
import {Dialog} from 'your-component-library';

<PopoverTrigger label="Open Popover">
  <Dialog title="Popover title">
    This is the content of the popover.
  </Dialog>
</PopoverTrigger>

// Reuse the Dialog from your component library. See below for details.
import {Dialog} from 'your-component-library';

<PopoverTrigger label="Open Popover">
  <Dialog title="Popover title">
    This is the content
    of the popover.
  </Dialog>
</PopoverTrigger>

Dialog#

The Dialog component is rendered within the Popover component. It is built using the useDialog hook, and can also be used in other overlay containers such as modals.

function Button(props) {
  let ref = props.buttonRef;
  let { buttonProps } = useButton(props, ref);
  return (
    <button {...buttonProps} ref={ref} style={props.style}>
      {props.children}
    </button>
  );

Usage#

The following examples show how to use the Popover and PopoverTrigger components created in the above example.

Placement#

The popover's placement with respect to its anchor element can be adjusted using the placement prop. See Placement for a full list of available placement combinations.

<div style={{ display: 'flex', gap: 8 }}>
  <PopoverTrigger placement="start" label="⬅️">
    <Dialog>
      In left-to-right, this is on the left. In right-to-left, this is on the
      right.
    </Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="top" label="⬆️">
    <Dialog>This popover is above the button.</Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="bottom" label="⬇️">
    <Dialog>This popover is below the button.</Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="end" label="➡️">
    <Dialog>
      In left-to-right, this is on the right. In right-to-left, this is on the
      left.
    </Dialog>
  </PopoverTrigger>
</div>

<div style={{ display: 'flex', gap: 8 }}>
  <PopoverTrigger placement="start" label="⬅️">
    <Dialog>
      In left-to-right, this is on the left. In
      right-to-left, this is on the right.
    </Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="top" label="⬆️">
    <Dialog>This popover is above the button.</Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="bottom" label="⬇️">
    <Dialog>This popover is below the button.</Dialog>
  </PopoverTrigger>
  <PopoverTrigger placement="end" label="➡️">
    <Dialog>
      In left-to-right, this is on the right. In
      right-to-left, this is on the left.
    </Dialog>
  </PopoverTrigger>
</div>

<div
  style={{
    display: 'flex',
    gap: 8
  }}
>
  <PopoverTrigger
    placement="start"
    label="⬅️"
  >
    <Dialog>
      In left-to-right,
      this is on the
      left. In
      right-to-left,
      this is on the
      right.
    </Dialog>
  </PopoverTrigger>
  <PopoverTrigger
    placement="top"
    label="⬆️"
  >
    <Dialog>
      This popover is
      above the button.
    </Dialog>
  </PopoverTrigger>
  <PopoverTrigger
    placement="bottom"
    label="⬇️"
  >
    <Dialog>
      This popover is
      below the button.
    </Dialog>
  </PopoverTrigger>
  <PopoverTrigger
    placement="end"
    label="➡️"
  >
    <Dialog>
      In left-to-right,
      this is on the
      right. In
      right-to-left,
      this is on the
      left.
    </Dialog>
  </PopoverTrigger>
</div>

Offset and cross offset#

The popover's offset with respect to its anchor element can be adjusted using the offset and crossOffset props. The offset prop controls the spacing applied along the main axis between the element and its anchor element whereas the crossOffset prop handles the spacing applied along the cross axis.

Below is a popover offset by an additional 50px above the trigger.

<PopoverTrigger placement="top" offset={50} label="Trigger">
  <Dialog>
    Offset by an additional 50px.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger placement="top" offset={50} label="Trigger">
  <Dialog>
    Offset by an additional 50px.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger
  placement="top"
  offset={50}
  label="Trigger"
>
  <Dialog>
    Offset by an
    additional 50px.
  </Dialog>
</PopoverTrigger>

Below is a popover cross offset by an additional 100px to the right of the trigger.

<PopoverTrigger placement="top" crossOffset={100} label="Trigger">
  <Dialog>
    Offset by an additional 100px.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger
  placement="top"
  crossOffset={100}
  label="Trigger"
>
  <Dialog>
    Offset by an additional 100px.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger
  placement="top"
  crossOffset={100}
  label="Trigger"
>
  <Dialog>
    Offset by an
    additional 100px.
  </Dialog>
</PopoverTrigger>

Flipping#

By default, usePopover attempts to flip popovers on the main axis in situations where the original placement would cause it to render out of view. This can be overridden by setting shouldFlip={false}. To see the difference between the two options, scroll this page so that the example below is near the bottom of the window.

<PopoverTrigger placement="bottom" label="Default">
  <Dialog>
    This is a popover that will flip if it can't fully render below the button.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger placement="bottom" shouldFlip={false} label="shouldFlip=false">

Container padding#

You can control the minimum padding required between the popover and the surrounding container via the containerPadding prop. This affects the positioning breakpoints that determine when it will attempt to flip.

The example below will maintain at least 50px between the popover and the edge of the browser window.

<PopoverTrigger placement="top" containerPadding={50} label="Trigger">
  <Dialog>
    This is a popover.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger
  placement="top"
  containerPadding={50}
  label="Trigger"
>
  <Dialog>
    This is a popover.
  </Dialog>
</PopoverTrigger>

<PopoverTrigger
  placement="top"
  containerPadding={50}
  label="Trigger"
>
  <Dialog>
    This is a popover.
  </Dialog>
</PopoverTrigger>

`triggerRef`	`RefObject<Element \| null>`	—	The ref for the element which the popover positions itself with respect to.
`popoverRef`	`RefObject<Element \| null>`	—	The ref for the popover element.
`isNonModal`	`boolean`	—	Whether the popover is non-modal, i.e. elements outside the popover may be interacted with by assistive technologies. Most popovers should not use this option as it may negatively impact the screen reader experience. Only use with components such as combobox, which are designed to handle this situation carefully.
`isKeyboardDismissDisabled`	`boolean`	`false`	Whether pressing the escape key to close the popover should be disabled. Most popovers should not use this option. When set to true, an alternative way to close the popover with a keyboard must be provided.
`shouldCloseOnInteractOutside`	`( (element: Element )) => boolean`	—	When user interacts with the argument element outside of the popover ref, return true if onClose should be called. This gives you a chance to filter out interaction with elements that should not dismiss the popover. By default, onClose will always be called on interaction outside the popover ref.
`arrowSize`	`number`	`0`	Cross size of the overlay arrow in pixels.
`boundaryElement`	`Element`	`document.body`	Element that that serves as the positioning boundary.

`containerPadding`	`number`	`12`	The placement padding that should be applied between the element and its surrounding container.
`offset`	`number`	`0`	The additional offset applied along the main axis between the element and its anchor element.
`crossOffset`	`number`	`0`	The additional offset applied along the cross axis between the element and its anchor element.
`shouldFlip`	`boolean`	`true`	Whether the element should flip its orientation (e.g. top to bottom or left to right) when there is insufficient room for it to render completely.
