Hello ECharts team, We are currently using the ECharts tree chart component to visualize hierarchical data in a solution being developed for a major Oil & Gas company in Brazil.
One specific behavior requested by our client is the ability to **automatically collapse sibling nodes when a node is expanded**. The idea is that when a user opens a node, all other nodes at the same level should collapse, showing only the branch of the node that was clicked. This helps reduce visual clutter and allows for a more focused user experience, especially in large tree structures. This feature is of high importance because the tool is already being used by key stakeholders, including board-level executives and investors. We reviewed the documentation and examples (e.g., [https://echarts.apache.org/examples/en/editor.html?c=tree-basic](https://echarts.apache.org/examples/en/editor.html?c=tree-basic)) but did not find a built-in option or recommended workaround to achieve this behavior. Would it be possible to support this functionality in future versions of ECharts? Or is there a recommended approach to implement this behavior using current APIs? Thank you very much for your excellent work on this project. We look forward to hearing your thoughts.
