描述

Would it work if one was to set the hasCaret prop to whether or not children are available, display a spinner upon onExpand while fetching content from elsewhere, and then replace the spinner with the actual content upon completion?

If so, what would be an elegant way to display a spinner? At first glance, it seems like the only valid type of children are again tree nodes. Those could at least have a label "loading" and be disabled for the time being, however I would much rather prefer a spinner. Could the children prop be used for this?

Thanks for any hints.

研究方向
Explore the Tree component's source code in the Blueprint repository (likely in packages/core/src/components/tree/). Investigate how other Blueprint components like Button or Spinner implement loading states. Review any existing discussions in the issue comments for design preferences. Consider implementing a loading spinner that appears next to a tree node when its children are being fetched asynchronously.
