Tree View

Breaking changes

• The component used to animate the item children is now defined as a slot on the TreeItem component.

  If you were passing a TransitionComponent or TransitionProps to your TreeItem component, you need to use the new groupTransition slot on this component:

   <SimpleTreeView>
      <TreeItem
        nodeId="1"
        label="Node 1"
  -     TransitionComponent={Fade}
  +     slots={{ groupTransition: Fade }}
  -     TransitionProps={{ timeout: 600 }}
  +     slotProps={{ groupTransition: { timeout: 600 } }}
      />
    </SimpleTreeView>
  

• The group class of the TreeItem component has been renamed to groupTransition to match with its new slot name.

   const StyledTreeItem = styled(TreeItem)({
  -  [`& .${treeItemClasses.group}`]: {
  +  [`& .${treeItemClasses.groupTransition}`]: {
      marginLeft: 20,
    },
   });
