  This is a demo: https://stackblitz.com/edit/js-fbrjdf?file=index.js,data.js,style.css

  How do I specify not to collapse on any row that I want?
  
  I want to prevent collapse in Child2. The other rows still collapse normally
  
  I hope anyone helps me. Thank you very much.

  Hello,

  You may handle the isCollapsedChanging event of TreeView and cancel the node collapse when a specific node gets collapsed/expand. Please refer to the code snippet and sample link below demonstrating the same:

    isCollapsedChanging: (s, e) => {
      if (e.node.dataItem.header == 'Child2') {
        e.cancel = true;
      }
    },
