Hello, everyone,  
I'd like to create a custom node, with dynamic editor, which changes it's form controls (like dropdown options) with ajax inside. Is it possible to implement within oneditprepare? Or should I use ui dashboard instead?

I go through google and find something very approximate [here](https://apiko.com/blog/node-red-pallets-development/), still unsure of the limit of node editor

Your `oneditprepare` function can contain whatever javascript you need in order to build the edit dialog. We include jQuery as the utility library of choice.

A lot of the core nodes are examples of building the edit dialogs dynamically - such as the Switch and Change nodes - although none use ajax.

Thanks for your quick response. Sorry if I didn't tell the question clearly.

What I want to implement is like a multi-select form control, which is more dynamic than config properties of subflow. Let's call it a configuable dataset.

- When editing the node, I could change some form control (let's say filter fields), and request data api to populate results for multiple selection.

- The selected results could be passed out on input msg.

This seems to be easy with website client. I don't know if it is suitable or possible to implement in a custom node.

After more searching, I found a [solution](https://discourse.nodered.org/t/show-apis-response-in-node-ui/3424/16) by you earlier which seems to be exactly I want..

Let's make it clear.. the editor dialog is just same with a running web client, and can do whatever I want with a remote server.. right?
