(treeview) auto collapse on certain folders only

[Khairul]

Hi,
I've been using treeview for a while now and was wondering, is there a
setting or modification that I can use to make only a certain folders
collapsed on load? Based on the options available that I read, it only
has collapse all, or none. What I want to do is just collapse the very
top folder without collapsing any subfolder beneath it.

Can this be done?

Thanks.
