Do you have a screenshot and more description of what you already has been implemented?
Unfortunately, that's impossible, there is no such thing exposed in the Mendix client. What you could try to do is make a view Entity which acts as your container. Then add an extra association from your Node to view and call this selection. When you click on a row, execute a microflow that sets this association. In your data view on the right you could do a retrieve to get this referenced Node.
It's complicated.
