Avoid expand sub-menu

[thomasbruchet]

Hello
I would like to know if is it possible to avoid to expand the sub-menu of the explorer ?
See on: https://i.imgur.com/T3em1KZ.png
When I click on [03.Script], I've all the submenu that expand and I think that is not necessary.
I want to expand only the submenu that I Click.

WHen I clic on [03.Script] I want only to have the 3 sub
01-AutoHotKey
02-Autoit
03-Python

Then When I clic on one on this submenu, I want that is the only one to expand.

How can I can do that ?
