dbFront does not have any treeview capability.
dbFront can show self referencing tables (where the table has a foreign key to itself) and it will show the parent and the immediate child, but there is no treeview option to allow you to quickly see more levels.
It is also possible to create a Stored Procedure that returns the treeview structure as HTML and then you can use dbFront to display that to the user with a RunProcedure button.
Thanks for this request.
