W4rl0ck Without getting into total rewrites and preset lists the only filter you can do is by the file names
so you could have a link like
<a href="?cat=skandal">Skandal</a>
and in your filelist add
filter="*{_$cat|}*.*"
or in xtscript you just 'get' the variable and use it directly
filter="*$cat*.*"
* == any sequence of chars
so it looks for a match anywhere in the file name
.* at the end means it will reject any file without a extension (like index)
