I intend to use this wonderfull menu for a website and need some help. Is it possible to collapse only the second and following levels, but not the first one, when on small devices?
The reason is that the website has a sticky topbar with 3 icons: menu, search and language. They should remain align horizontally, on the same line, regardless of screen size. Here’s a scrrenshot:

And another question: is it possible to hide submenu indicators for the top level, of the same reason.
I really hope that it is possible, because I really love this menu.
Thank you very much!
