如何使vis.js网络上的边不可选？

var edges = [
  {id: 1, from: 1, to: 2, selectionWidth: 0},
  {id: 2, from: 2, to: 3, selectionWidth: 0},
  // 其他边的定义
];

var nodes = [
  {id: 1, label: 'Node 1'},
  {id: 2, label: 'Node 2'},
  {id: 3, label: 'Node 3'},
  // 其他节点的定义
];

var data = {
  nodes: nodes,
  edges: edges,
};

var options = {};

var container = document.getElementById('network');

var network = new vis.Network(container, data, options);
