I'm looking at Node-RED docs/api/ui/treelist, but I don't know how to apply it.  
I want to see some basic example of treelist.  
Please help me!!

There is info and examples in the help: [TreeList Widget : Node-RED](https://nodered.org/docs/api/ui/treeList/)

Also, you can look at how existing nodes do it e.g. the link nodes: [node-red/60-link.html at master · node-red/node-red · GitHub](https://github.com/node-red/node-red/blob/master/packages/node_modules/@node-red/nodes/core/common/60-link.html#L150)

Thanks for the reply.  
But, I still can't apply it...  
So I asked question again at below link.
