The options for the interaction module have to be contained in an object titled 'interaction'.

Click on the full options or shorthand options to show how these options are supposed to be used.

// these are all options in full.
var options = {
  interaction:{
    dragNodes:true,
    dragView: true,
    hideEdgesOnDrag: false,
    hideNodesOnDrag: false,
    hover: false,
    hoverConnectedEdges: true,
    keyboard: {
      enabled: false,
      speed: {x: 10, y: 10, zoom: 0.02},
      bindToWindow: true
    },
    multiselect: false,
    navigationButtons: false,
    selectable: true,
    selectConnectedEdges: true,
    tooltipDelay: 300,
    zoomView: true
  }
}

network.setOptions(options);

// only the options that have shorthand notations are shown.
var options = {
  interaction:{
    keyboard: false
  }
}

network.setOptions(options);
