Dendogram collapse issue with many child nodes

[renjiie]

Hi I tried the vertical dendogram with antv g6 but for more children nodes the collapse is not working properly. On click of the node it is not getting collapsed. For the demo data it is working My code link is in : https://codesandbox.io/s/dendogram-antv-5v4y7?file=/src/treeGraph.js

The id of each node MUST be UNIQUE.

e.g. Following code assigns unique id for each node rather than name which might not unique.

let count = 0;
G6.Util.traverseTree(data1, subtree => {
  subtree.id = `node-${count}`;
  count++;
  return true;
});
