Modal is a lower-level construct that is leveraged by the following components:

If you are creating a modal dialog, you probably want to use the Dialog component rather than directly using Modal.

Props

Props of the native component are also available.

NameTypeDefaultDescription
children*element
A single child content element.
⚠️ Needs to be able to hold a ref.
open*boolfalse
If true, the component is shown.
classesobject
Override or extend the styles applied to the component. See CSS API below for more details.

containerHTML element
| func
An HTML element or function that returns one. The container will have the portal children appended to it.
By default, it uses the body of the top-level document object, so it's simply document.body most of the time.
disableAutoFocusboolfalse
If true, the modal will not automatically shift focus to itself when it opens, and replace it to the last focused element when it closes. This also works correctly with any modal children that have the disableAutoFocus prop.
Generally this should never be set to true as it makes the modal less accessible to assistive technologies, like screen readers.
disableEnforceFocusboolfalse
If true, the modal will not prevent focus from leaving the modal while open.
Generally this should never be set to true as it makes the modal less accessible to assistive technologies, like screen readers.
disableEscapeKeyDownboolfalse
If true, hitting escape will not fire the onClose callback.
disablePortalboolfalse
The children will be under the DOM hierarchy of the parent component.
disableRestoreFocusboolfalse
If true, the modal will not restore focus to previously focused element once modal is hidden or unmounted.
disableScrollLockboolfalse
Disable the scroll lock behavior.
