FormPush
Renders a button that will push items to an array value in the form store when clicked.
The name prop needs to be
provided to identify the array field. The
value prop is required to
define the value that will be added to the array.
By default, the newly added input will be automatically focused when the
button is clicked unless the
autoFocusOnClick
prop is set to false.

const values = form.useState("values");

Required Props
name
StringLike
Name of the array field. This can either be a string or a reference to a
field name from the
names object in the
store, for type safety.
value
unknown
Value that will initially be assigned to the array item when it's pushed.
Optional Props
accessibleWhenDisabled
boolean | undefined
Indicates whether the element should be focusable even when it is
disabled.
This is important when discoverability is a concern. For example:
A toolbar in an editor contains a set of special smart paste functions that are disabled when the clipboard is empty or when the function is not applicable to the current content of the clipboard. It could be helpful to keep the disabled buttons focusable if the ability to discover their functionality is primarily via their presence on the toolbar.

Live examples
autoFocus
boolean | undefined = false
Automatically focuses the element upon mounting, similar to the native
autoFocus prop. This addresses an issue where the element with the native
autoFocus attribute might receive focus before React effects are
executed.
The autoFocus prop can also be used with
Focusable elements within a
Dialog component, establishing the
initial focus as the dialog opens.
Note: For this prop to work, the
focusable prop must be
set to true, if it's not set by default.
Live examples
autoFocusOnClick
boolean | undefined = true
Whether the newly added input should be automatically focused when the button is clicked.
clickOnEnter
boolean | undefined = true
If set to true, pressing the enter key while this element is focused will
trigger a click on the element, regardless of whether it's a native button
or not. If this prop is set to false, pressing enter will not initiate a
click.
clickOnSpace
boolean | undefined = true
If set to true, pressing and releasing the space key while this element
is focused will trigger a click on the element, regardless of whether it's
a native button or not. If this prop is set to false, space will not
initiate a click.
disabled
boolean | undefined = false
Determines if the element is disabled. This sets the aria-disabled
attribute accordingly, enabling support for all elements, including those
that don't support the native disabled attribute.
This feature can be combined with the
accessibleWhenDisabled
prop to make disabled elements still accessible via keyboard.
Note: For this prop to work, the
focusable prop must be
set to true, if it's not set by default.
Live examples
focusable
boolean | undefined = true
Determines if Focusable features should be active on non-native focusable elements.
Note: This prop only turns off the additional features provided by the
Focusable component.
Non-native focusable elements will lose their focusability entirely.
However, native focusable elements will retain their inherent focusability,
but without added features such as improved
autoFocus,
accessibleWhenDisabled,
onFocusVisible,
etc.
getItem
((props: CollectionStoreItem) => CollectionStoreItem) | undefined
A memoized function that returns props to be passed with the item during its registration in the store.
Code examples
const getItem = useCallback((data) => ({ ...data, custom: true }), []);
id
string | undefined
The unique ID of the item. This will be used to register the item in the
store and for the element's id attribute. If not provided, a unique ID
will be automatically generated.
Live examples
onFocusVisible
BivariantCallback<(event: React.SyntheticEvent<HTMLElement, Event>) => void> | undefined
Custom event handler invoked when the element gains focus through keyboard
interaction or a key press occurs while the element is in focus. This is
the programmatic equivalent of the
data-focus-visible
attribute.
Note: For this prop to work, the
focusable prop must be
set to true, if it's not set by default.

render
RenderProp<React.HTMLAttributes<any> & { ref?: React.Ref<any> | undefined; }> | React.ReactElement<any, string | React.JSXElementConstructor<any>> | undefined
Allows the component to be rendered as a different HTML element or React component. The value can be a React element or a function that takes in the original component props and gives back a React element with the props merged.
Check out the Composition guide for more details.
shouldRegisterItem
boolean | undefined = true
Whether the item should be registered as part of the collection.
store
FormStore<FormStoreValues> | undefined
Object returned by the
useFormStore hook. If not
provided, the closest Form or
FormProvider components'
context will be used.
