如何在仍然在cytoscape.js中显示子节点时隐藏复合节点

问题描述 投票:2回答:1

我想创建一个图形,其中一些节点是“复合”节点,嵌入几个子节点,但不显示它们:应显示子节点,但应隐藏化合物。

作为布局,我使用了名为dagre-cytoscape的cytoscape.js扩展。

到目前为止,我创建了一个只有复合节点所具有的“复合”类,并且我尝试设置opacity:0或visibility:仅为此类隐藏,但是这些选项中的每个选项都变为不可见。

这是一个非工作示例的bin:

<body>
  <h1>cytoscape-dagre test</h1>
  <div id="cy"></div>

</body>

</html>

jsbin version

在此示例中,隐藏节点n1和n2以及父节点。我想保持父隐藏,但有n1和n2可见。

尝试将复合节点的background-opacityborder-width设置为0。
