@bianic-ui/modal

A modal is a window overlaid on either the primary window or another dialog window. Contents behind a modal dialog are inert meaning that users cannot interact with content behind the dialog.

Installation

yarn add @bianic-ui/modal

# or

npm i @bianic-ui/modal

Import components

import {
  Modal,
  ModalOverlay,
  ModalContent,
  ModalHeader,
  ModalFooter,
  ModalBody,
  ModalCloseButton,
} from "@bianic-ui/core"

Usage

When the modal opens, focus is sent into the modal and set to the first tabbable element. If there are no tabbled element, focus is set on the ModalContent.

function BasicUsage() {
  const { isOpen, onOpen, onClose } = useDisclosure()
  return (
    <>
      <Button onClick={onOpen}>Open Modal</Button>

      <Modal isOpen={isOpen} onClose={onClose}>
        <ModalOverlay>
          <ModalContent>
            <ModalHeader>Modal Title</ModalHeader>
            <ModalCloseButton />

            <ModalBody>
              <Lorem count={2} />
            </ModalBody>

            <ModalFooter>
              <Button colorScheme="blue" mr={3} onClick={onClose}>
                Close
              </Button>
              <Button variant="ghost">Secondary Action</Button>
            </ModalFooter>
          </ModalContent>
        </ModalOverlay>
      </Modal>
    </>
  )
}

Control Focus when Modal closes

When the dialog closes, it returns focus to the element that triggered. Set finalFocusRef to element that should receive focus when the modal opens.

function ReturnFocus() {
  const { isOpen, onOpen, onClose } = useDisclosure()
  const finalRef = React.useRef()

  return (
    <>
      <Box ref={finalRef} tabIndex={-1} aria-label="Focus moved to this box">
        Some other content that'll receive focus on close.
      </Box>

      <Button mt={4} onClick={onOpen}>
        Open Modal
      </Button>

      <Modal finalFocusRef={finalRef} isOpen={isOpen} onClose={onClose}>
        <ModalOverlay>
          <ModalContent>
            <ModalHeader>Modal Title</ModalHeader>
            <ModalCloseButton />
            <ModalBody>
              <Lorem count={2} />
            </ModalBody>

            <ModalFooter>
              <Button colorScheme="blue" mr={3} onClick={onClose}>
                Close
              </Button>
              <Button variant="ghost">Secondary Action</Button>
            </ModalFooter>
          </ModalContent>
        </ModalOverlay>
      </Modal>
    </>

function AlertDialogExample() {
  const [isOpen, setIsOpen] = React.useState()
  const onClose = () => setIsOpen(false)
  const cancelRef = React.useRef()

  return (
    <>
      <Button colorScheme="red" onClick={() => setIsOpen(true)}>
        Delete Customer
      </Button>

      <AlertDialog
        isOpen={isOpen}
        leastDestructiveRef={cancelRef}
        onClose={onClose}
      >
        <AlertDialogOverlay>
          <AlertDialogContent>
            <AlertDialogHeader fontSize="lg" fontWeight="bold">
              Delete Customer
            </AlertDialogHeader>

            <AlertDialogBody>
              Are you sure? You can't undo this action afterwards.
            </AlertDialogBody>

            <AlertDialogFooter>
              <Button ref={cancelRef} onClick={onClose}>
                Cancel
              </Button>
              <Button colorScheme="red" onClick={onClose} ml={3}>
                Delete
              </Button>
            </AlertDialogFooter>
          </AlertDialogContent>
        </AlertDialogOverlay>
