Modal (Dialog)
A dialog 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.
Import#
Chakra exports 8 components to help you create any modal dialog.
Modal
: The wrapper that provides context for its childrenModalOverlay
: The dimmed overlay behind the modal dialogModalContent
: The container for the modal dialog's contentModalHeader
: The header that labels the modal dialogModalFooter
: The footer that houses the modal actionsModalBody
: The wrapper that houses the modal's main contentModalCloseButton
: The button that closes the modal.
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
.
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 closes.
Block Scrolling when Modal opens#
For accessibility, it's recommended to block scrolling on the main document
behind the modal. Chakra does this by default but you can set
blockScrollOnMount
to false
to allow scrolling behind modal.
Focus on specific element#
Chakra automatically sets focus on the first tabbable element in the modal. However, there might be scenarios where you need to manually control where focus goes.
Chakra provides 2 props for this use-case:
initialFocusRef
: Theref
of the component that receives focus when the modal opens.finalFocusRef
: Theref
of the component that receives focus when the modal closes.
If you set finalFocusRef
, internally we set returnFocusOnClose
to false
so it doesn't return focus to the element that triggered it.
Prevent Modal from closing on Overlay click#
By default, the modal closes when you click it's overlay. You can set
closeOnOverlayClick
to false
if you want the modal to stay visible.
Make modal vertically centered#
By default the modal has a vertical offset of 3.75rem
which you can change by
passing top
to the ModalContent
. If you need to vertically center the modal,
pass the isCentered
If the content within the modal overflows beyond the viewport, don't use this prop. Try setting the overflow behavior instead
Adding transition#
The modal doesn't come with any transition by default so you can manage this
yourself. Chakra exports two transition components SlideIn
and Scale
to
provide simple transitions.
For some reason, focus doesn't return back to the trigger after the transition
ends. As a walkaround, you might need to set finalFocusRef
to the trigger or
any other element, and set isOpen
to true
.
Modal overflow behavior#
If the content within the modal overflows beyond the viewport, you can use the
scrollBehavior
to control how scrolling should happen.
- If set to
inside
, scroll only occurs within theModalBody
. - If set to
outside
, the entireModalContent
will scroll within the viewport.
Modal Sizes#
Pass the size
prop if you need to adjust the size of the modal. Values can be
xs
, sm
, md
, lg
, xl
, or full
.
Preserving the scrollbar gap#
By default, scrolling is blocked when the modal opens. This can lead to unpleasant content shift.
To prevent this, pass the preserveScrollBarGap
prop. It applies a
padding-right
to the body element that's equal to the width of the browser's
scrollbar.
Making other elements Inert#
When the modal is open, it's rendered within a portal and all it's siblings have
aria-hidden
set to true
so the only thing screen readers see is the modal.
To disable this behavior, set useInert
to false
.
Accessibility#
Keyboard and Focus Management#
- When the modal opens, focus is trapped within it.
- When the dialog opens, focus is automatically set to the first enabled
element, or the element with the
initialFocusRef
. - When the modal closes, focus returns to the element that was focused just
before the modal activated, or the element with the
finalFocusRef
- Clicking on the overlay closes the Modal.
- Pressing Esc closes the Modal.
- Scrolling is blocked on the elements behind the modal.
- The modal is portalled to the end of
document.body
to break it out of the source order and make it easy to addaria-hidden
to its siblings.
ARIA#
- The
ModalContent
hasaria-modal
set totrue
. - The
ModalContent
hasaria-labelledby
set to theid
of theModalHeader
- The
ModalContent
hasaria-describedby
set to theid
of theModalBody
