One very small question regarding categories.

I have phpBB2

Hello all. I just have a tiny question regarding my forum. I made a category for my forum titled, "Lyrics". The problem is: I didn't want the sub-forums in the lyrics category to be popped out like that rather for them to be hidden. Is there a way that I can configure, my lyrics category so when guests click on "lyrics" the next page will show them the sub-categories/forums?

Thanks in advance for the help.

Here is my forum so you can further understand what I mean.

In admin panel,
Display>Structure and Hierarchy
Split categories on index :
Select None

See if that helps.
