Popover

Popover is a non-modal dialog that floats around a trigger.

    SourceTheme source@chakra-ui/popover

Popover is built on top of the Popper.js library.

Import#

  • Popover: The wrapper that provides props, state, and context to its children.
  • PopoverTrigger: Used to wrap the reference (or trigger) element.
  • PopoverContent: The popover itself.
  • PopoverHeader: The header of the popover.
  • PopoverBody: The body of the popover.
  • PopoverArrow: A visual arrow that points to the reference (or trigger).
  • PopoverCloseButton: A button to close the popover.
  • PopoverAnchor: Used to wrap the position-reference element.
import {
Popover,
PopoverTrigger,
PopoverContent,
PopoverHeader,
PopoverBody,
PopoverFooter,
PopoverArrow,
PopoverCloseButton,
PopoverAnchor,
} from '@chakra-ui/react'

Basic Usage#

It is used to display contextual information to the user, and should be paired with a clickable trigger element.

When Popover opens, focus is sent to PopoverContent. When it closes, focus is returned to the trigger.

Tip: When using this component, ensure the children passed to PopoverTrigger is focusable and has a forwarded ref.

<Popover>
<PopoverTrigger>
<Button>Trigger</Button>
</PopoverTrigger>
<PopoverContent>
<PopoverArrow />
<PopoverCloseButton />
<PopoverHeader>Confirmation!</PopoverHeader>
<PopoverBody>Are you sure you want to have that milkshake?</PopoverBody>
</PopoverContent>
</Popover>

Rendering the Popover in a Portal#

By default, the Popover doesn't render in a Portal. To make them display in a portal, wrap the PopoverContent in a Portal

You might need to Inspect Element to see this in action. Notice that PopoverContent is rendered as a child of <body>

<Popover>
<PopoverTrigger>
<Button>Trigger</Button>
</PopoverTrigger>
<Portal>
<PopoverContent>
<PopoverArrow />
<PopoverHeader>Header</PopoverHeader>
<PopoverCloseButton />
<PopoverBody>
<Button colorScheme='blue'>Button</Button>
</PopoverBody>
<PopoverFooter>This is the footer</PopoverFooter>
</PopoverContent>
</Portal>
</Popover>

Focus an element when Popover opens#

By default, focus is to sent to PopoverContent when it opens. Pass the initialFocusRef prop to send focus to a specific element instead.

Focusing a child element only works for popovers with a click trigger, not hover.

function WalkthroughPopover() {
const initialFocusRef = React.useRef()
return (
<Popover
initialFocusRef={initialFocusRef}
placement='bottom'
closeOnBlur={false}
>
<PopoverTrigger>
<Button>Trigger</Button>
</PopoverTrigger>
<PopoverContent color='white' bg='blue.800' borderColor='blue.800'>
<PopoverHeader pt={4} fontWeight='bold' border='0'>
Manage Your Channels
</PopoverHeader>
<PopoverArrow />
<PopoverCloseButton />
<PopoverBody>
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod tempor incididunt ut labore et dolore.
</PopoverBody>
<PopoverFooter
border='0'
display='flex'
alignItems='center'
justifyContent='space-between'
pb={4}
>
<Box fontSize='sm'>Step 2 of 4</Box>
<ButtonGroup size='sm'>
<Button colorScheme='green'>Setup Email</Button>
<Button colorScheme='blue' ref={initialFocusRef}>
Next
</Button>
</ButtonGroup>
</PopoverFooter>
</PopoverContent>
</Popover>
)
}

Trapping Focus within Popover#

If the popover contains a form, you might need to trap focus within the popover and close it when the user fills the form and hits "save".

You can leverage react-focus-lock to trap focus within the PopoverContent.

// import FocusLock from "react-focus-lock"
// 1. Create a text input component
const TextInput = React.forwardRef((props, ref) => {
return (
<FormControl>
<FormLabel htmlFor={props.id}>{props.label}</FormLabel>
<Input ref={ref} id={props.id} {...props} />
</FormControl>
)
})
// 2. Create the form
const Form = ({ firstFieldRef, onCancel }) => {
return (
<Stack spacing={4}>
<TextInput
label='First name'
id='first-name'
ref={firstFieldRef}
defaultValue='John'
/>
<TextInput label='Last name' id='last-name' defaultValue='Smith' />
<ButtonGroup display='flex' justifyContent='flex-end'>
<Button variant='outline' onClick={onCancel}>
Cancel
</Button>
<Button isDisabled colorScheme='teal'>
Save
</Button>
</ButtonGroup>
</Stack>
)
}
// 3. Create the Popover
// Ensure you set `closeOnBlur` prop to false so it doesn't close on outside click
const PopoverForm = () => {
const { onOpen, onClose, isOpen } = useDisclosure()
const firstFieldRef = React.useRef(null)
return (
<>
<Box display='inline-block' mr={3}>
John Smith
</Box>
<Popover
isOpen={isOpen}
initialFocusRef={firstFieldRef}
onOpen={onOpen}
onClose={onClose}
placement='right'
closeOnBlur={false}
>
<PopoverTrigger>
<IconButton size='sm' icon={<EditIcon />} />
</PopoverTrigger>
<PopoverContent p={5}>
<FocusLock returnFocus persistentFocus={false}>
<PopoverArrow />
<PopoverCloseButton />
<Form firstFieldRef={firstFieldRef} onCancel={onClose} />
</FocusLock>
</PopoverContent>
</Popover>
</>
)
}
render(<PopoverForm />)

Controlled Usage#

You can control the opening and closing of the popover by passing the isOpen, and onClose props.

Sometimes you might need to set the returnFocusOnClose prop to false to prevent popover from returning focus to PopoverTrigger's children.

function ControlledUsage() {
const { isOpen, onToggle, onClose } = useDisclosure()
return (
<>
<Button mr={5} onClick={onToggle}>
Trigger
</Button>
<Popover
returnFocusOnClose={false}
isOpen={isOpen}
onClose={onClose}
placement='right'
closeOnBlur={false}
>
<PopoverTrigger>
<Button colorScheme='pink'>Popover Target</Button>
</PopoverTrigger>
<PopoverContent>
<PopoverHeader fontWeight='semibold'>Confirmation</PopoverHeader>
<PopoverArrow />
<PopoverCloseButton />
<PopoverBody>
Are you sure you want to continue with your action?
</PopoverBody>
<PopoverFooter display='flex' justifyContent='flex-end'>
<ButtonGroup size='sm'>
<Button variant='outline'>Cancel</Button>
<Button colorScheme='red'>Apply</Button>
</ButtonGroup>
</PopoverFooter>
</PopoverContent>
</Popover>
</>
)
}

Popover Anchor#

You can wrap your component with PopoverAnchor to prevent trigger any action. The wrapped component will become a position reference. Actions will only be triggered by components inside PopoverTrigger.

In this case, you can only open and close the popover with Button. If you click on Input, it acts same as the original input and doesn't trigger any action about popover.

🚨 Note: As with PopoverTrigger, if you use a custom component inside PopoverAnchor ensure that it uses Chakra's forwardRef so the popover is triggered successfully.

function WithPopoverAnchor() {
const [isEditing, setIsEditing] = useBoolean()
const [color, setColor] = React.useState('red')
return (
<Popover
isOpen={isEditing}
onOpen={setIsEditing.on}
onClose={setIsEditing.off}
closeOnBlur={false}
isLazy
lazyBehavior='keepMounted'
>
<HStack>
<PopoverAnchor>
<Input
color={color}
w='auto'
display='inline-flex'
isDisabled={!isEditing}
defaultValue='Popover Anchor'
/>
</PopoverAnchor>
<PopoverTrigger>
<Button h='40px' colorScheme='pink'>
{isEditing ? 'Save' : 'Edit'}
</Button>
</PopoverTrigger>
</HStack>
<PopoverContent>
<PopoverBody>
Colors:
<RadioGroup value={color} onChange={(newColor) => setColor(newColor)}>
<Radio value='red'>red</Radio>
<Radio value='blue'>blue</Radio>
<Radio value='green'>green</Radio>
<Radio value='purple'>purple</Radio>
</RadioGroup>
</PopoverBody>
</PopoverContent>
</Popover>
)
}

Accessing Internal state#

Chakra provides access to two internal details: isOpen and onClose. Use the render prop pattern to gain access to them.

function InternalStateEx() {
const initRef = React.useRef()
return (
<Popover closeOnBlur={false} placement='left' initialFocusRef={initRef}>
{({ isOpen, onClose }) => (
<>
<PopoverTrigger>
<Button>Click to {isOpen ? 'close' : 'open'}</Button>
</PopoverTrigger>
<Portal>
<PopoverContent>
<PopoverHeader>This is the header</PopoverHeader>
<PopoverCloseButton />
<PopoverBody>
<Box>
Hello. Nice to meet you! This is the body of the popover
</Box>
<Button
mt={4}
colorScheme='blue'
onClick={onClose}
ref={initRef}
>
Close
</Button>
</PopoverBody>
<PopoverFooter>This is the footer</PopoverFooter>
</PopoverContent>
</Portal>
</>
)}
</Popover>
)
}

Customizing the Popover#

Chakra exports all the components you need to customize the look and feel of the popover. You can change the background, arrow size, box shadow and so on.

<Popover>
<PopoverTrigger>
<Box
tabIndex='0'
role='button'
aria-label='Some box'
p={5}
w='120px'
bg='gray.300'
children='Click'
/>
</PopoverTrigger>
<PopoverContent bg='tomato' color='white'>
<PopoverHeader fontWeight='semibold'>Customization</PopoverHeader>
<PopoverArrow bg='pink.500' />
<PopoverCloseButton bg='purple.500' />
<PopoverBody>
Tadaa!! The arrow color and background color is customized. Check the
props for each component.
</PopoverBody>
</PopoverContent>
</Popover>

Popover Placements#

Since popover is powered by PopperJS, you can change the placement of the popover by passing the placement prop. See the props for the possible placement values.

Even though you specified the placement, Popover will try to reposition itself in the event that available space at the specified placement isn't enough.

<Popover placement='top-start'>
<PopoverTrigger>
<Button>Click me</Button>
</PopoverTrigger>
<PopoverContent>
<PopoverHeader fontWeight='semibold'>Popover placement</PopoverHeader>
<PopoverArrow />
<PopoverCloseButton />
<PopoverBody>
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore.
</PopoverBody>
</PopoverContent>
</Popover>

Lazily mounting Popover#

By default, the Popover component renders children of PopoverContent to the DOM, meaning that invisible popover contents are still rendered but are hidden by styles.

If you want to defer rendering of popover content until that Popover is opened, you can use the isLazy prop. This is useful if your PopoverContent needs to be extra performant, or make network calls on mount that should only happen when the component is displayed.

<Popover isLazy>
<PopoverTrigger>
<Button>Click me</Button>
</PopoverTrigger>
<PopoverContent>
<PopoverHeader fontWeight='semibold'>Popover placement</PopoverHeader>
<PopoverArrow />
<PopoverCloseButton />
<PopoverBody>
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore.
</PopoverBody>
</PopoverContent>
</Popover>

Accessibility#

When you see the word "trigger", it is referring to the children of PopoverTrigger

Keyboard and Focus#

  • When the popover is opened, focus is moved to the PopoverContent. If the initialFocusRef is set, then focus moves to the element with that ref.
  • When the popover is closed, focus returns to the trigger. If you set returnFocusOnClose to false, focus will not return.
  • If trigger is set to hover:
    • Focusing on or mousing over the trigger will open the popover.
    • Blurring or mousing out of the trigger will close the popover. If you move your mouse into the PopoverContent, it'll remain visible.
  • If trigger is set to click:
    • Clicking the trigger or using the Space or Enter when focus is on the trigger will open the popover.
    • Clicking the trigger again will close the popover.
  • Hitting the Esc key while the popover is open and focus is within the PopoverContent, will close the popover. If you set closeOnEsc to false, it will not close.
  • Clicking outside or blurring out of the PopoverContent closes the popover. If you set closeOnBlur to false, it will not close.

ARIA Attributes#

  • If the trigger is set to click, the PopoverContent element has role set to dialog. If the trigger is set to hover, the PopoverContent has role set to tooltip.
  • The PopoverContent has aria-labelledby set to the id of the PopoverHeader.
  • The PopoverContent has aria-describedby set to the id of the PopoverBody.
  • The PopoverContent has aria-hidden set to true or false depending on the open/closed state of the popover.
  • The trigger has aria-haspopup set to true to denote that it triggers a popover.
  • The trigger has aria-controls set to the id of the PopoverContent to associate the popover and the trigger.
  • The trigger has aria-expanded set to true or false depending on the open/closed state of the popover.
