  Hi,
  
  You can handle dblclick event for the same. You can collapse/expand by setting isCollapsed property to false/true for selectedNode. You also need to set expandOnClick property to false.

  
  tree.expandOnClick=false;
  tree.hostElement.addEventListener("dblclick",function(e){
  	tree.selectedNode.isCollapsed=!tree.selectedNode.isCollapsed;
  });

  Hi,
  
  If you would like to expand node on click, you may set to expandOnClick property to true . For this, you need not to handle click event.

  If you set to expandOnClick or handle click event to expand node, node expand on double click would not be work properly. Since, double click event triggered when click action occurs within a time frame which will trigger click event.

  If the issue persists, please let us know.
