This is a simple folder tree UI component made with JS. 

I wanted a component easy to read and understand how it is creating the folders. 

Code isn't minified so anyone can download and change it however they want :)

Use the FolderTree block and wrapped it in an If conditional for Is Data Fetch from the data source aggregate.

If an orphan is find (one that isn't a root folder) a console.log message will popup, so keep an eye on that.

Actions you can use:

• TriggerEvent_Initialized non-mandatory event was added so the consumer can respond to the folder tree being initialized.
• SetFolderActive client action to set a folder active programatically.
