Make 2. level menue appear instantly?

Hey there,

I'm really a newbie to skinning, so I started out editing the current one. I'm starting to feel a wee comfortable, and I actually managed to get most of the sings changed, that I want to.

But one thing, I don't have a clue how that could be done:

This is how it is:
When you scroll the main menu, let's say to Music, and Music has a submenue with Albums, Songs, Artists,...., the submenue only shows up when you push down (or right, depending on the skin).

I understand that this is done by <ondown>GROUPID</ondown>.

What I'd like is:
that the submenu is shown, as soon as you're on Music.

Could anybody give me a hint how this could be done?

Any advice is greatly appreciated.

Never mind.
