how to occult CTree lines?

[mrl netbank com br]

Hi all,

I would like to know if there is a way to occult a CTree item or would do you
usually do to work-around this..
I need this for my mpg123 frontend, that searches the musics based on regex..
So I put all on the CTree and then I kindly "traverse" it comparing.. it's fast.! but I realy need to occult 
some lines..
I tried moving it to another column, setting it's cell contents to Empty, but nothing worked..
What do you think?
