Hint text is not showing

Hi Team,
I created a doc picker compound like below. I have added hint text. But in cms i am not able to see hint text message. Please help me on this.

Looking at the code, the ExternalTreeItemFieldSelectorPlugin (and its super) doesn’t support hints like the default PropertyFieldPlugin does. It needs some Wicket coding for that.

This is an open source plugin on our GitHub Forge [1] where contributions are welcome so if you’re up to it, you can fork, do a pull request etc.
