Multiple categories w/ column layout?

Hi Tuan,
Is it possible to do a column layout with multiple categories/sub-categories displaying on the same page and their documents displaying under them?

At the moment, we don't support that layout. Do you have a sample example so that I can look at it and implement it into the extension ?

I believe it would be nice to have this kind of layout supported in the extension !

Regards,

Tuan
