This is my custom websocket node. As you see the msg it outputs is an object  
`{ name: datapointname, value: data }`  
Could i somehow create Select tag that has options based on how many msg.payload it recives. Options text would be the `datapointname` property and the value would be `data` property

```auto
module.exports = function(RED) {
    function wsListenerNode(config) {
        RED.nodes.createNode(this,config); 
        this.path = config.path;
        var node = this;
        node.on('input', function(msg) {  
            const WebSocket = require ("ws") // Require Websocket
            let path = node.path;
            let ws = new WebSocket(path); //Connect to the WebSocket //ws://192.168.1.41:22080/webevent/ 
        ws.onopen = (e) => {
              console.log(e);
                setTimeout(function () {
                  ws.send(
                    msg.payload
                  );
                }, 1000);
            };
        ws.onmessage = (e) => {
              msg.payload = e.data;
              var stripped = msg.payload.trim();
              var values = stripped.split("\n");
      
              var datapointname = values[0].substring(37, values[0].length - 14);
              data = Number(values[1]);
              msg.payload = {name:datapointname,value: data}
              node.send(msg)
                };
        });
    }
    RED.nodes.registerType("websocketListener",wsListenerNode);
}

```

I want to display the result when i open the node

I think you will find this question has been answered in the last few days. Yes, you can create a dropdown using a select tag. You need to use the `oneditprepare` function to set it up and manage it.
