Focusable
Renders a focusable element. When this element gains keyboard focus, it gets
a
data-focus-visible
attribute and triggers the
onFocusVisible
prop.
The Focusable component supports the
disabled prop for all
elements, even those not supporting the native disabled attribute. Disabled
elements using the Focusable component may be still accessible via keyboard
by using the the
accessibleWhenDisabled
prop.
Code examples
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
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.
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.
