Dragging node makes a node selected/highlighted on vis.js

Question

Dragging a network node in vis.js library highlights/selects that node, and when drag ends the node still appears has highlighted/selected. I would like to prevent that behavior so nodes are selected only on click and not on drag , or even better on drag end to clear that highlighting. I believe it is possible through dragEnd network event but I played with it a bit with no success. Any hints?

Example for the behavior: https://visjs.github.io/vis-network/examples/network/basic_usage/legacy.html

This can be achieved with a combination of the dragEnd event and the unselectAll method, like:

network.on('dragEnd', function(){
  network.unselectAll();
});

A working snippet is below:

 // create an array with nodes let nodes = new vis.DataSet([ { id: 1, label: "Node 1" }, { id: 2, label: "Node 2" }, { id: 3, label: "Node 3" }, { id: 4, label: "Node 4" }, { id: 5, label: "Node 5" }, ]); // create an array with edges let edges = new vis.DataSet([ { from: 1, to: 3 }, { from: 1, to: 2 }, { from: 2, to: 4 }, { from: 2, to: 5 }, { from: 3, to: 3 }, ]); // create a network const container = document.getElementById("mynetwork"); const data = { nodes: nodes, edges: edges, }; const options = {}; const network = new vis.Network(container, data, options); // When dragging ends clear selection network.on('dragEnd', function(){ network.unselectAll(); });

 #mynetwork { width: 600px; height: 160px; border: 1px solid lightgray; }

 <script src="https://visjs.github.io/vis-network/standalone/umd/vis-network.min.js"></script> <div id="mynetwork"></div>

Alternatively you could restore the previous selection when the drag ends, a sample of this can be seen at https://jsfiddle.net/ckx2apgs/ .
