Not delete a node

Hello,

I am trying the following example.

http://gojs.net/latest/samples/flowchart.html

But I need that one specific category (“start”) can not bve deleted.

So other nodes can be deleted, but the category ‘Start’ not. Is this possible?



Sure, just set deletable: false in the Node template:
myDiagram.nodeTemplateMap.add(“Start”,
$(go.Node, “Spot”, nodeStyle(),
{ deletable: false },
. . .

Wonderfull!
Thanks a lot!
