I am trying to achieve 2 things.
How do I select the first item "root", before the first render. i.e. there must always be a selected item
The context menu allows renaming, adding and deleting nodes. The rename option can be accomplished by double clicking with the mouse, BUT, how do I invoke this functionality from the Rename option in the context menu, i.e. in the contextClickProcess method.
It looks like you're new here. If you want to get involved, click one of these buttons!
