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.

Defines the human readable text alternative of aria-valuenow for a range widget.
The component to render the item's content in. This should normally stay as
the default "span" element, but if you'd like to make a navigation tree,
this can be set as a Link component from a routing library.
Example:
<TreeItem href="#" contentComponent="a" />
<TreeItem to="/example-url" contentComponent={Link} exact />
The current depth that the tree item is being rendered at. This will be a
number starting from 1 since it should be directly mapped to
"aria-posinset".
Boolean if the tree item is disabled which will prevent it from being interactable. It will still be "keyboard focusable" while disabled, but clicking or selecting won't work.
Boolean if the tree item is expanded. When this is true, it should add
aria-expanded="true" to the tree item.
The icon to show within each item within the tree that helps show that there are child items.
NOTE: This will override the rightAddon prop if defined on each item by
default so they can't be used. If the expanderLeft prop is enabled, the
leftAddon will be overridden instead.
Boolean if the expander icon should appear to the left instead of the right.
Boolean if the tree item is the current keyboard focus.
Boolean if the left and/or right addons should be "forcefully" wrapped in a
<span> with the spacing class names applied instead of attempting to
clone it into the provided icon element.
The height to apply to the list item.
Conversions:
A DOM id for the tree item. This is required for a11y since this id should
reflect the aria-activedescendant value on the base Tree component to
show current keyboard focus.
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
Boolean if the TreeItem is a link component which changes up how the
accessibility attributes are applied to the DOM. The default behavior is to
check if the contentComponent is to consider it a link if it is not a
string (custom component) or the string: "a". Since this might cause some
false-positives, you can set this flag instead which will always be used
instead.
The current tree item's index within its list at the provided depth. This
will be a number starting from 1 since it should be directly mapped to
"aria-posinset".
An optional addon to display to the left of the primaryText or
children and should be used with the leftAddonType prop to adjust
spacing.
The vertical position the left icon, avatar, media, or large media should be placed.
The type of the addon that appears to the left of the primaryText or
children.
An optional className to apply to the surrounding <li> element for the
tree item. The className prop is actually passed to the
contentComponent element instead since you normally don't want to apply
styles to the surrounding element.
An optional ref to apply to the content of the tree item.
An optional style to apply to the surrounding <li> element for the tree
item. The style prop is actually passed to the contentComponent element
instead since you normally don't want to apply styles to the surrounding
element.
The current total list size for the tree item at the provided depth. This
should be mapped directly into "aria-setsize".
An optional element that should be rendered as the primaryText within the
list item. It is most likely easier to use the children prop instead, but
this allows you to create more complex components with the ListItem since
you can provided children and have the styles for the primaryText still
applied. By default, this will only allow one line of text and add ellipsis
for any text overflow.
Boolean if the tree item is read only. Not sure why this was added though
since <li> elements don't support readOnly.
An optional addon to display to the right of the primaryText or
children and should be used with the rightAddonType prop to adjust
spacing.
The vertical position the right icon, avatar, media, or large media should be placed.
The type of the addon that appears to the right of the primaryText or
children.
An optional element that should be rendered as the secondaryText within
the list item. By default, this will only span one line and add ellipsis
for overflow.
An optional className to apply to the <span> that surrounds the
secondaryText within the list item.
Boolean if the tree item is currently selected.
Boolean if the children should be treated as the primaryText prop. This
will wrap them in an additional class so that they have ellipsis for text
overflow.
If you want to have more "freedom" within the ListItem, you can disable
this prop so that the height will grow depending on content.
NOTE: If the secondaryText prop is provided, this will always be
considered true.
An optional className to apply to the <span> that surrounds the
primaryText and optionally secondaryText within the list item.
Boolean if the list item should be considered "three-lines" in height. This
will update the secondaryText to span 2 lines instead of one, but it will
not correctly applied the trailing ellipsis overflow due to browser
compatibility of line-clamp. If you would still like the ellipsis to
show, it is recommended to use javascript to add them yourself.
This function will only be provided when the tree item has child tree
items. This function should only be called within the exported TreeGroup
component or in a component that has the role="group" for accessibility.
