Indicates whether assistive technologies will present all, or only parts of, the changed region based on the change notifications defined by the aria-relevant attribute.
Indicates whether inputting text could trigger display of one or more predictions of the user's intended value for an input and specifies how predictions would be presented if they are made.

The animation classNames
applied to the component as it enters or exits.
A single name can be provided and it will be suffixed for each stage: e.g.
classNames="fade"
applies fade-enter
, fade-enter-active
,
fade-exit
, fade-exit-active
, fade-appear
, and fade-appear-active
.
Each individual classNames can also be specified independently like:
classNames={{
appear: 'my-appear',
appearActive: 'my-appear-active',
appearDone: 'my-appear-done',
enter: 'my-enter',
enterActive: 'my-enter-active',
enterDone: 'my-enter-done',
exit: 'my-exit',
exitActive: 'my-exit-active',
exitDone: 'my-exit-done'
}}
The component to render the dialog as. This really shouldn't be used
outside of the @react-md/layout
and @react-md/sheet
packages to
conditionally render a navigation panel.
An optional className to apply to the dialog container when the type
is
set to "centered"
or when the forceContainer
prop is enabled. You
probably don't want to use this prop in most cases.
An optional style to apply to the dialog container when the type
is set
to "centered"
or when the forceContainer
prop is enabled. You probably
don't want to use this prop in most cases.
Either the "first" or "last" string to focus the first or last focusable element within the container or a query selector string to find a focusable element within the container.
Boolean if the ability to close the dialog via the escape key should be disabled. You should really not be using this as it breaks accessibility in most cases.
Note: When the modal
prop is enabled, this flag will be considered true
as well so that the escape keypress no longer closes the dialog.
By default, the focus container will try to maintain a cache of the focusable elements that is updated only when this component re-renders. If the children are extremely dynamic and focusable elements can be removed/added without this component updating, you should disable the cache so that the focusable elements are updated each time the tab key is pressed. Disabling the cache will be slightly slower for larger focusable areas, but it might not be too bad.
NOTE: The only important elements are the first and last elements in this list. So if your children aren't changing the first and last elements, there's no need to disable the cache.
Boolean if the dialog's focus container logic should be disabled. This
should normally be kept at the default of false
unless implementing a
custom dialog that does not require consistent user focus.
The default behavior for the focus container is to focus an element once it
is mounted and the disabled
prop is not enabled. This behavior can be
disabled if this is not wanted for some reason.
Boolean if the element that gets focused on mount should try to not scroll
the focused element into view which is the default behavior. This should
normally remain false
, but it is useful to set to true
if the
FocusContainer
is within a transition that appears offscreen.
The default behavior for the focus container is to attempt to focus the element that was focused before the focus container was mounted since it is generally used for temporary material. If there are cases where this behavior is not wanted, you can enable this prop.
The Dialog component will attempt to automatically fix nested dialogs
behind the scenes using the NestedDialogContextProvider
component. This
prop will disable that feature if it does not seem to be working as
expected.
Boolean if the dialog should no longer add scroll locking to the page when
visible. You normally want this prop to stay false
, but it is useful when
using custom dialogs that are more for popovers and don't require full user
attention.
Boolean if the focus behavior should be disabled. This should really be used if you are using nested focus containers for temporary material (such as dialogs or menus).
Boolean if the appear
, enter
, and exit
transitions should be disabled
for the dialog. This is just a shortcut so all three of those props don't
need to be disabled.
Enable or disable enter transitions.
Enable or disable exit transitions.
The size to use for sheets that have been positioned left or right. The default supported values are:
min-width
is set to be the entire viewport width minus a
touchable area and max-width
is set to 20rem
and is normally
recommended for mobile devices.16rem
and generally used for
landscape tablets and desktops.An id required for a11y for the dialog.
Show the component; triggers the enter or exit states
Hints at the type of data that might be entered by the user while editing the element or its contents
Specify that a standard HTML element should behave like a defined custom built-in element
By default the child component is mounted immediately along with the
parent Transition component. If you want to "lazy mount" the component on
the first in={true}
you can set mountOnEnter
. After the first enter
transition the component will stay mounted, even on "exited", unless you
also specify unmountOnExit
.
Callback fired before the "entering" status is applied. An extra
parameter isAppearing
is supplied to indicate if the enter stage is
occurring on the initial mount
Callback fired after the "entered" status is applied. An extra parameter isAppearing is supplied to indicate if the enter stage is occurring on the initial mount
Callback fired after the "entering" status is applied. An extra parameter isAppearing is supplied to indicate if the enter stage is occurring on the initial mount
Callback fired before the "exiting" status is applied.
Callback fired after the "exited" status is applied.
Callback fired after the "exiting" status is applied.
Boolean if there should be an overlay displayed with the sheet. This is recommended/required on mobile devices.
An optional className to apply to the overlay.
Boolean if the overlay should be "hidden" from the user once it's visible
be keeping the opacity set to 0
. This is really only used for custom
dialogs like the FixedDialog
.
An optional style to apply to the overlay.
Boolean if the portal should be used.
The location that the sheet should be located within the viewport.
The role that the sheet should be rendered as. You'll normally want to keep
this as the default of "dialog"
unless you are implementing a mobile
sheet menu.
Note: Setting this to "menu"
will not provide the menu keyboard
accessibility automatically.
The tab index for the sheet. This should normally stay at -1
.
When the focus container unmounts, it will attempt to re-focus the element
that was focused before the focus container was mounted unless the
disableFocusOnUnmount
prop is enabled. There might be cases where
unmounting the focus container causes the page to re-render and the
previous element no longer exists. When this happens keyboard users might
have a problem navigating through the page again depending on how the
browser implemented the native tab behavior so this prop allows you to
ensure that a specific element is focused in these cases.
This can either be a query selector string, a specific HTMLElement, or a function that finds a specific HTMLElement to focus.
By default the child component stays mounted after it reaches the
'exited' state. Set unmountOnExit
if you'd prefer to unmount the
component after it finishes exiting.
The size to use for sheets that have been positioned top or bottom. The supported sizes are:
Boolean if the dialog is currently visible.
A function used to close the dialog when the overlay is clicked or the
escape key is pressed when the modal
prop is not enabled.
Generated using TypeDoc
Normally a component is not transitioned if it is shown when the
<Transition>
component mounts. If you want to transition on the first mount set appear to true, and the component will transition in as soon as the<Transition>
mounts. Note: there are no specific "appear" states. appear only adds an additional enter transition.
