有没有办法在Cytoscape.js中显示从复合节点到子节点的连接

我正在探索Cytoscape.js的潜力,并想知道是否可以可视化从复合节点(父节点)到该节点内的子节点的连接。

在下面的例子中,我想展示父节点' b'和孩子们一起去和' c',但到目前为止,我没有成功。

下面给出了最小的工作示例,并在此处进行了编辑:http://jsbin.com/lelinaduko/3/edit

    elements: {
        nodes: [
          { data: { id: 'a', parent: 'b' } },
          { data: { id: 'c', parent: 'b' } },
          { data: { id: 'd' } },
          { data: { id: 'e' } },
          { data: { id: 'f', parent: 'e' } },
          { data: { id: 'b' } }
        ],
        edges: [
          { data: { id: 'bd', source: 'b', target: 'd' } },
          { data: { id: 'eb', source: 'e', target: 'b' } },
          { data: { id: 'ca', source: 'c', target: 'a' } },
          { data: { id: 'ab', source: 'a', target: 'b' } },
          { data: { id: 'bc', source: 'b', target: 'c' } }

        ]
      },

您似乎发现了一个错误:

如果您想在新版本之前解决问题,请使用干草堆边缘 - 因为这些边缘不受影响。
