Select form with tree structure in custom node

Hi! I need to create a select form with tree structure for my custom node edit display. I'm wondering if it's possible to use this:
Can I use jqTree in the html file? or do I have to create a script in the js file and then use $.getScript() in the html?
Sorry if my cuestion is to basic, but I don't have much experience with HTML.
Thanks in advance!

You can use extra libraries - but it is non-trival - you can see an example of how it is done in the node-red-node-geofence -

An alternative if you know the depth of your tree would be a set of dropdowns - where a selection in the top level one populates the next etc... via a series of fetches from the server.

Hey Dave (@dceejay),
Could the new TreeList widget (from version 0.20.0) be of any use here??? I haven't seen it in action yet, so I might have misunderstood what it could be used for ...

Probably. As the page you link to says, it has pretty minimal functionality currently, so without more details of the actual requirements, I couldn't say if it's a complete fit.

And of course that would mean the node would only work on 0.20 or later.


I think it's exactly what a need! Is there any complete example?
Thank you very much!


But as already noted, this is only available in version 0.20 onwards

And just to repeat - it has very minimal functionality - just enough for what we use it for in 0.20. It may not do everything you want it to.

Does that include 20 beta4? Is it a UI Node for use by end users in Thier flows?

Sorry if this is a stupid question (I did have a quick look at the links)

No. It is a common element for use by nodes in their edit dialogs. It has nothing to do with Node-RED Dashboard.
