This only applied when navigating "back" (to a lower index) to Panel. When navigating "forwards" (to a higher index), the Panel and its contained components will use their default state.

Sets the strategy used to automatically focus an element within the panel upon render.

• "none" - Automatic focus is disabled

• "last-focused" - The element last focused in the panel with be restored

• "default-element" - The first spottable component within the body will be focused

• Custom Selector - A custom CSS selector may also be provided which will be used to find the target within the Panel

When used within Panels, this prop may be set by Panels to "default-element" when navigating "forward" to a higher index. This behavior may be overridden by setting autoFocus on the Panel instance as a child of Panels or by wrapping Panel with a custom component and overriding the value passed by Panels.

// Panel within CustomPanel will always receive "last-focused"
const CustomPanel = (props) => <Panel {...props} autoFocus="last-focused" />;

// The first panel will always receive "last-focused". The second panel will receive
// "default-element" when navigating from the first panel but `autoFocus` will be unset
// when navigating from the third panel and as a result will default to "last-focused".
const MyPanels = () => (
  <Panels>
    <Panel autoFocus="last-focused" />
    <Panel />
    <Panel />
  </Panels>
);

The "aria-label" for the Panel.

By default, the panel will be labeled by its Header. When aria-label is set, it will be used instead to provide an accessibility label for the panel.

Obtains a reference to the root node.

Customizes the component by mapping the supplied collection of CSS class names to the corresponding internal elements and states of this component.

The following classes are supported:

• panel - The root class name

• body - The node containing the panel's children

Header for the panel.

This is usually passed by the Slottable API by using a Header component as a child of the Panel.

Hides the body components.

When a Panel is used within Panels this property will be set automatically to true on render and false after animating into view.

Prevents the component from restoring any framework shared state.

When false, the default, Panel will store state for some framework components in order to restore that state when returning to the Panel. Setting this prop to true will suppress that behavior and not store or retrieve any framework component state.
